Texto completoRecent years have witnessed a lack of momentum in equity markets that has driven a growing number of investors to turn to private markets, including private equity.This manuscript addresses research questions that characterize the changes that private equity is experiencing today: a search for relative liquidity, a quest for superior returns in new markets, and a stability in human capital, which remains an important vector of communication during fundraising.The first dissertation of this thesis examines the impact of the public listing of private equity vehicles on their performance and shows that exposure to liquidity induces significantly lower realized performances.The second dissertation examines the performance of private equity in emerging markets and shows that the success of these investments is related to the geographic distance and the cultural proximity between private equity firms and the investee companies.Finally, the last dissertation of this thesis examines the importance of human capital for private equity firms and shows that manager mobility deteriorates performance

Texto completoParking management is a key element in the sustainable mobility paradigm. In this research, starting from available information sources, whether quantitative or qualitative, mobility pattern in UAB and the way it is conditioned by parking policy, are diagnosed. Likewise, criteria and strategic lines are proposed to facilitate parking policy to establish appropriate conditions for a sustainable mobility pattern in the framework of an integral mobility policy. In UAB, a metropolitan knowledge node, mobility pattern is explained by captivity with respect to different means of transport, cost of the trip and social and economic personal characteristics of users. The high level of captivity in relation to public transport (53%), is one of the reasons of high demand (60%). However, this is not the only reason. In conditions of eligibility, perception of cost of the trip (time and economic cost), influenced by social and economic conditions of users as well as their place of residence, is the decision making aspect. 30% of those owning a car use public transport regularly, while a 20% of those who have a good option of public transportation drive to Campus. Public transportation is relatively more used from central areas, like Barcelona, where quotidian relationship of citizens and transport is intense, due to transport quantity and quality. Instead, trips from municipalities on the peripheral areas of the metropolitan area, though public transportation availability in connection to Campus, less presence of this transport in quotidian life of citizens, especially related to inter municipal trips, turns into unnecessary use of car. This unnecessary use from places with good transport is fostered, among other things, by the absence of a parking policy which regulates demand. Free parking and incapacity to control illegal parking, distort offer and demand relationship within transport election process and encourage solo driver car use. Despite modal split in UAB is favourable to public transportation, and environmental impacts are kept within reasonable limits, excessive presence of cars produce a series of impacts at social and functional level. On the one hand, people with no reasonable public transportation option, compete for a scarce resource in the same conditions, getting less access opportunities as a result. Likewise, occupation by cars of spaces directed to other users, limit their rights. On the other hand, parking, distributed in a non-homogeneous and efficient way, misses its function within the general mobility scheme. With the aim of minimising these aspects, this research proposes to stablish a parking policy which reduces the number of cars in Campus. The main elements for this policy are eliminating illegal parking and stablish a subsidized rate which favours those students and staff who have less options, those who have weaker economic power, and more sustainable use of car (high occupancy cars and propelled by clean renewable energies), considering spatial and temporal variability of demand. Such a policy, accompanying and subsidizing active and collective transports, is essential to achieve a sustainable, efficient and equitable mobility pattern.

Texto completoVirtual Private Networks (VPNs) are designed to use the Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) to establish secure communication tunnels over public Internet. Multipath TCP (MPTCP) extends TCP to allow data to be delivered over multiple network paths simultaneously. This thesis first builds a testbed and investigates the potential of using MPTCP tunnels to increase the goodput of VPN communications and support seamless mobility. Based on the empirical results and an analysis of the MPTCP design in Linux kernels, we further introduce a full-multipath kernel, implementing a basic Multipath UDP (MPUDP) protocol into an existing Linux MPTCP kernel.We demonstrate the MPUDP protocol provides performance improvements over single path UDP tunnels and in some cases MPTCP tunnels. The MPUDP kernel should be further developed to include more efficient scheduling algorithms and path managers to allow better performance and mobility benefits seen with MPTCP.

The "sustainability" literature generally acknowledges a critical role for transportation infrastructure planning, finance, investment, design, construction, operation, and management for addressing the long-term viability of cities and metropolitan areas. At the same time, governments have increasingly employed public-private partnerships (PPPs) for metropolitan transportation infrastructure with the goal of improving project finance, delivery, and long-term management and operation. While proponents of "sustainability" often imply a more collectivist and public-sector-led paradigm and proponents of liberalization often argue for greater private sector intervention and market competition, theory suggests that both sectors offer unique institutional attributes critical to achieving sustainable metropolitan mobility (SMM). The question is how to optimally configure institutions to address the challenge of SMM for metropolitan transportation infrastructure delivery? Focusing on highways, this thesis adopts a broad definition of SMM that compasses efficient road pricing and regulation, integration of metropolitan transportation policy, public acceptability, and technology. It employs a qualitative case study analysis to test theories on optimal institutional configurations against seven cases across the world where PPPs were used to deliver highway infrastructure in metropolitan areas. The results suggest that the distribution of network, traffic, and demand risks; the spatial configuration of highways within metropolitan areas; and political factors play key roles in achieving SMM. Additionally, issues of vertical devolution and integration of government institutions and contract regulation likely play important roles but require more in-depth research.

Texto completoIn the past decades, the usage of GPS-enabled smartphones has dramatically risen. However, all these usages do not come without privacy threats. Indeed, location data that users are sending to these services can be used to infer sensitive knowledge about them, such as where they live or where they work. This is were protection mechanisms come into play, whose goal is to put users back in control of their privacy. We start by surveying existing protection mechanisms and metrics used to evaluate them. This first analysis highlights a particularly sensitive information, namely the points of interest. These are all the places where users use to spend most of their time. This leads us towards building a new protection mechanism, PROMESSE, whose main goal is to hide these points of interest. Protection mechanisms tend to be configured by parameters, which highly impact their effectiveness in terms of privacy and utility. We propose ALP, a solution to help users to configure their protection mechanisms from a set of objectives they specified. Finally, we introduce Accio, which is a software encompassing most of our work. Its goal is to allow to easily launch location privacy experiments and enforce their reproducibility

Texto completoThis work seeks to understand the implementation of subway lines in São Paulo and analyze the Companhia do Metropolitano de São Paulo, from its formation, in the 1960s, to the present time. The research also attempts to verify who were the main national and international actors, from the public and private sectors, that participated in the decisions on this public policy in question. For this purpose, the processes of decision making and implementation of the lines 1 - Blue, 3 - Red, 2 - Green and 4 - Yellow were analyzed. With the findings of the research it is possible to argue that the Metrô of São Paulo has undergone a downgrading of its technical staff and its state capabilities, characteristic of its constitution, that gave space to the interest of private actors inside the company, resulting in loss to the public company and in backlog of works. This process occurred with the rise and fall of a model of developmentalist State and the emergence of new visions of State influenced by New Public Management.

Texto completoWhy is it that in France almost one out of every four pupils changes schools during his/her secondary school years ? Based on a survey done in a secondary school and on a framework designed to analyse school placements, this study completes the findings of recent sociological research focusing on school placements. First of all, this analysis focuses on the range of schools in a particular area. A description of the basic structure of the schools shows how infrequently these models are changed. This study encourages a reflection on the distinction between the practices of the public schools and private schools concerning under privilèges populations. The research then concentrates on the choices which best benefit both the families and the school staff. Through this study emerges an existing tension between the legislation which created this framework governing educational placements and the rights families have to send their children tout the schools of their choice in accordance with their expectations of what a school should provide. The pupils' mobility is the logical consequence of having to readjust to the various social and educative dispositions of the pupils and those already in place in their successive schools. Taking into account the flow from one local secondary school to another, this report also brings to the forefront an increasing homogeneity of groups of pupils from a similar social background in both the classroom and in the school from the beginning and the end of secondary school years

Texto completoThe terminology "legal mobility" emerges from the movement of personnel in organized and normative sets larger than the enterprise. Initially, this notion made it possible to highlight the change in the working relationship when the latter, without losing its connection with an enterprise located in a state legal order, deploys abroad, in the direction of a new state order. to a new company. Legal mobility is a mobility by change of the applicable law. It is the result of a spatial shift in the working relationship between mutually irreducible normative spaces. The foundation of legally mobile working relationships is formed by organizations outside formal organizations. These are incomplete organizations. These induce coordination requirements.In a first part, it is taken care of to release the normative coordinations as first. It is from these that the coordination modalities of the people involved in mobility can be induced. it shows a renewed figure of the employer (it will be about the masters of the organization). It also shows a renewed figure of the worker, whose development of "capabilities" implies a better anchoring of his rights in his normative environment of work and employment. It ultimately results in a renewed order of labor relations.In a second part, attention is paid to the similarity of the legal questions posed in a context of globalization to legally mobile working relationships, whether they are deemed to be purely internal or international. The coordination of the legal orders concerns the coordination of companies and workers: it is a coordination of coordination, carried out through a plurality of principles and methods. It reveals the existence of an international private labor law contributing to the transnational organization of labor relations.Ultimately, the functions of labor law and private international law are put to the test in the context of (s) national and international market(s)

Texto completoSweden has been at the forefront of electronic identification, especially with BankID, which had approximately 8 million users in 2019. Because mobile BankID is so common and meets good security, some municipalities have used it to identify their employees. Using BankID as e-identification in the workplace has been discussed for a long time and has led to some opposition from employees.The purpose of this study is to investigate how Skaraborg's municipalities use private e-identifications.The study addresses which systems private e-identification is used for, why municipalities have chosen it and any problems they have encountered. The data will be collected through interviews with the responsible employees at the municipalities. The results show that the municipalities use private e-identifications like BankID for many different systems and did not show a clear pattern for which system it was used for. The municipalities'reasoning for using mobile BankID was that partly for financial reasons where the municipality had to follow a budget and practical reasons as many already have mobile BankID, which facilitated their implementation. The majority of the municipalities considered that using private mobile BankID in the workplace is not necessarily something negative as it meets the security requirements set and is easilyaccessíble. The results also show that the employees were against the use of BankID as a identification, which has hindered implementation for municipalities. In cases where staff do not agree to use their private mobile BankID, most municipalities had an alternative solution.

Texto completoThe ever rising mobility requirements, especially in metropolitan areas, are constantly being confronted with the limited urban transport capacities. Spatial and financial restrictions often prohibit the building of new or the enhancement of existing infrastructure. Therefore, it is concluded that a better spatialarchitectural, organisational, and informational linkage of the different means of transport to form an „intermodal transportation system“ could provide a solution to this dilemma. Such an intermodal transportation system would encourage multiple mode travel. To implement such an intermodal transportation system, the main flaws of the existing public transport system would have to be eliminated: Traditional public transportation offers only a very low degree of individual availability and flexibility, measured by standards of modern lifestyles. A successful transfer of the now common standard qualities of private mobility to public transport would greatly increase their attractiveness. This paper describes the development of three exemplary product innovations which should help to bridge the described supply and quality gap: on the one hand, there are individualised public means of transport such as public bike rental or car rental schemes. And on the other hand, there is mobile ticketing as a means to offer simple, standardised and flexible access to public transport. The conceptualisation of these innovations took theoretically and empirically plausible assumptions about necessary product features into account. These features make it possible and easier for users to incorporate new transport services into their existing mobile routines. The implementation of the three product innovations was accompanied by research on their acceptance. Based on the results, the product features which decide the successful conceptualisation of individualised public means of transport are identified. The paper concludes with an outlook for a future form of intermodal auto-mobility.

Texto completoThe contracting mode public-private partnership (PPP) has been increasingly used in the world, and in Brazil, created by Law No. 11,079, is growing driven by mega sporting events like the World Cup 2014 and the Olympics in 2016, especially in infrastructure of urban mobility area. This thesis aims to make a value for money analysis for a PPP model contracting and therefore the credit through the contractual mode (PPP) of a prototype subway line in the city of Sao Paulo based on current Line 6 - Orange. After such an evaluation, it will also be verified through another prototype like Line 4 - Yellow which will enable the analysis of the higher value for money between the two prototypes of PPP existing in São Paulo with different scopes, one based on subway Line 4 - Yellow and other as the Line 6 - Orange, allowing to check the returns required by private entity in projects of this magnitude, in addition to predict the main difficulties and make recommendations and improvements. The study methodology is based on building a model to estimates costs and revenues of a prototype subway line in Sao Paulo city through a PPP model, based on Brazilian and international similar projects, specialized literature of the sector as well the assessment of legal, economic and financial aspects. Among conclusions, it was found that, given the difficulties of the public sector in leading major projects, such as lack of investment and expertise in planning, there is need for improvement in the procurement regime, such as the creation of specialized chambers to discuss the feasibility and appropriate division of risks between the private entity and the State in PPP projects through the comparison of both prototypes value for money proposed.

Texto completoThe ubiquity of sensors-equipped mobile devices has enabled people to contribute data via crowdsensing systems. This emergent paradigm comes with various applications. However, new challenges arise given users involvement in data collection process. In this context, we introduce collaborative sensing schemes which tackle four main questions: How to assign sensing tasks to maximize data quality with energy-awareness? How to minimize the processing time of sensing tasks? How to motivate users to dedicate part of their resources to the crowdsensing process ? and How to protect participants privacy and not impact data utility when reporting collected sensory data ? First, we focus on the fact that smart devices are energy-constrained and develop task assignment methods that aim to maximize sensor data quality while minimizing the overall energy consumption of the data harvesting process. The resulting contribution materialized as a Quality and Energy-aware Mobile Sensing Scheme (QEMSS) defines first data quality metrics then models and solves the corresponding optimization problem using a Tabu-Search based heuristic. Moreover, we assess the fairness of the resulted scheduling by introducing F-QEMSS variant. Through extensive simulations, we show that both solutions have achieved competitive data quality levels when compared to concurrent methods especially in situations where the process is facing low dense sensing areas and resources shortcomings. As a second contribution, we propose to distribute the assignment process among participants to minimize the average sensing time and processing overload com- pared to a fully centralized approach. Thus, we suggest to designate some participants to carry extra sensing tasks and delegate them to appropriate neighbors. The new assign- ment is based on predicting users local mobility and sensing preferences. Accordingly, we develop two new greedy-based assignment schemes, one only Mobility-aware (MATA) and the other one accounting for both preferences and mobility (P-MATA), and evaluate their performances. Both MATA and P-MATA consider a voluntary sensing process and show that accounting for users preferences minimize the sensing time. Having showing that, our third contribution in this thesis is conceived as an Incentives-based variant, IP-MATA+. IP-MATA+ incorporates rewards in the users choice model and proves their positive impact on enhancing their commitment especially when the dedicated budget is shared function of contributed data quality. Finally, our fourth and last contribution addresses the seizing of users privacy concerns within crowdsensing systems. More specifically, we study the minimization of the incurred privacy leakage in data uploading phase while accounting for the possible quality regression. That is, we assess simultaneously the two competing goals of ensuring queriers required data utility and protecting participants’ sensitive information. Thus, we introduce a trust entity to the crowdsensing traditional system. This entity runs a general privacy-preserving mechanism to release a distorted version of sensed data that responds to a privacy-utility trade-off. The proposed mechanism, called PRUM, is evaluated on three sensing datasets, different adversary models and two main data uploading scenarios. Results show that a limited distortion on collected data may ensure privacy while maintaining about 98% of the required utility level.The four contributions of this thesis tackle competing issues in crowdsensing which paves the way at facilitating its real implementation and aims at broader deployment

Texto completoThe wide diffusion of smart portable devices allows the collection of a big amount of data concerning the activities of users from mobile apps. We focus our attention on location data, i.e. mobility traces, of a set of users in a crowd. Data collected from these mobile systems are studied following two axies: - Mobility models are used to simulate the behavior of users to develop opportunistic forwarding algorithms. We compare real and synthetic mobility traces to show the distance between the reality and the models. - Information on mobility may endanger the privacy of users. We analyze the impact of such information on privacy of users. The main contributions are: - We analyze the spatial and social properties of human motion from real traces collected by a highly accurate experimental localization system. - We compare the real traces with synthetic mobility traces generated from seven popular mobility models - We provide an inference algorithm based on co-location of users and we show its efficiency on different datasets. - We quantify the effect of probabilistic co-location information by means of a novel co-location attack

Texto completoNowadays, the advances in the development of mobile devices, as well as embedded sensors have permitted an unprecedented number of services to the user. At the same time, most mobile devices generate, store and communicate a large amount of personal information continuously. While managing personal information on the mobile devices is still a big challenge, sharing and accessing these information in a safe and secure way is always an open and hot topic. Personal mobile devices may have various form factors such as mobile phones, smart devices, stick computers, secure tokens or etc. It could be used to record, sense, store data of user's context or environment surrounding him. The most common contextual information is user's location. Personal data generated and stored on these devices is valuable for many applications or services to user, but it is sensitive and needs to be protected in order to ensure the individual privacy. In particular, most mobile applications have access to accurate and real-time location information, raising serious privacy concerns for their users.In this dissertation, we dedicate the two parts to manage the location traces, i.e. the spatio-temporal data on mobile devices. In particular, we offer an extension of spatio-temporal data types and operators for embedded environments. These data types reconcile the features of spatio-temporal data with the embedded requirements by offering an optimal data presentation called Spatio-temporal object (STOB) dedicated for embedded devices. More importantly, in order to optimize the query processing, we also propose an efficient indexing technique for spatio-temporal data called TRIFL designed for flash storage. TRIFL stands for TRajectory Index for Flash memory. It exploits unique properties of trajectory insertion, and optimizes the data structure for the behavior of flash and the buffer cache. These ideas allow TRIFL to archive much better performance in both Flash and magnetic storage compared to its competitors.Additionally, we also investigate the protect user's sensitive information in the remaining part of this thesis by offering a privacy-aware protocol for participatory sensing applications called PAMPAS. PAMPAS relies on secure hardware solutions and proposes a user-centric privacy-aware protocol that fully protects personal data while taking advantage of distributed computing. For this to be done, we also propose a partitioning algorithm an aggregate algorithm in PAMPAS. This combination drastically reduces the overall costs making it possible to run the protocol in near real-time at a large scale of participants, without any personal information leakage

During the 2015 Paris Climate Change Conference, world climate scientists and policymakers agreed that global temperatures must not exceed a two degree Celsius increase above pre-industrial levels within the next 30 years. It is estimated that this will require investments of $40 trillion or $1.3 trillion per year in new and mature clean technologies. Currently, only about $0.3 trillion of investment goes to clean technology a year and the majority of that funding goes to mature, proven technologies. There is an investment gap in clean technologies, and the gap is especially pronounced for new and unproven technologies that are necessary to bring down costs of the entire system, and produce quicker breakthroughs in CO₂ mitigation. The gap is partly due to the large losses sustained by venture capitalists-one of the greatest source of early-stage capital-who invested heavily in clean technology companies in the years leading up to the 2008 recession. After the market crashed, federal and state governments ended up being among the few remaining supporters of these technology companies because of their public benefits. However, in order to stay below 2 degree Celsius warming, venture capitalists and other private venture investors must be engaged to invest in the clean technology sector again. Public sector funds are not sufficient. In a sector that has produced few winners while receiving substantial government support, the challenge could not be greater. To address this challenge, we ask three questions of three key actors: How can entrepreneurs attract private investment and scale up pass the Valley of Death? How can venture capitalists build the ability and confidence to invest in the cleantech sector again? How can policymakers address the failure modes that may still exist if investors and entrepreneurs follow best practices? To explore this issue, we conducted interviews, reviewed literature, compiled data from online sources, and compiled information from conferences and workshops. Our findings reveal a "Cleantech Confluence", or a preliminary set of best practices and partnerships. When simultaneously implemented, the Confluence can mobilize multiple sources of private capital into early-stage clean technologies.

Texto completoThe recent rise of smart-phones and connected objects has a deep impact its users lifestyle. In 2017, more than a billion and a half smart-phones were sold around the world. These ubiquitous devices, equipped with several wireless communication interfaces, have quickly become essential in the daily life of users with an intensive use. The wireless interfaces of these connected objects periodically transmit information on the network, some of which are user-specific and allow to identify and track their mobility. Tracking users by collecting the information generated by their wireless devices is called Wireless Physical Tracking. The opportunities offered by the Wireless Physical Tracking raised a lot of interest. Several applications have been developed and have brought innovation in several areas. Marketing companies use it to offer to their customers targeted advertising based on their movements in their area of activity. On a larger scale, Smart Cities or smart-cities analyse the movement of users in order to provide services for their inhabitants. Finally, in the field of research in mobile Ad-Hoc networks and DTNs, users mobility is a key element which need to be collected and analysed. However, the collection of this information without the consent of the users or without being properly protected induce a real risk to their privacy. It is around this context that this thesis is focused on. It’s divided into two parts. The first presents the PAN and WAN technologies, the state of the art of Wireless Physical Tracking methods and the adopted counter measures. The second part presents the contributions of the thesis which aims at developing new methods for Physical Tracking and analysing their performances compared to the existing methods. We first present an evaluate BPM, a bluetooth passive monitoring that allows to track the users of Classic Bluetooth device with a detection delay significantly lower than the methods previously used. We then focus on Bluetooth Low Energy and propose the use of a BLEB, a botnet of users tracking BLE objects with their smart-phones. Finally, we also focus on preserving users privacy through the proposal of PPCL, a privacy preserving crowdlocalisation method which allow to track users assets without being trackable

Texto completoThe thesis examines how international boarding schools in Switzerland have been producing spatial resources for their students and alumni. The research is based on socio-historical analysis, quantitative analysis, and on semi-directive interviews with headmasters and managers, alumni, teachers and boarding staff at a diversity of international private schools in the Lake Geneva region. The first part of the thesis focuses on the emergence of the private educational sector progressively uniting « boarding schools for foreigners » and « international schools ». Since the beginning of the 20th c., schools have promoted their territorial resources for attracting the very rich, notably from Europe and the United States, and organized sectorial interests accordingly. Swiss boarding schools now have a peripheral part to play in the international spheres of certification and accreditation that govern elite education on a global scale. Nevertheless, recent processes of financialization of the educational sector and ways of protecting the Swiss educational sector contribute to redefine their place within internationalizing governance schemes of elite schools. The second part of the thesis examines the role played by spatial resources in wealthy families’ educational strategies in Switzerland and the spatial relations to Switzerland that students and alumni develop. The notion of « refuge school » or « recovery school » encompasses three dimensions : the « family » education that the boarding schools promote, parental strategies of avoiding selective national educational systems, socio-political determinations. Under the rise of non-European and non-American wealthy clienteles, students’ national origins have changed since the 1950s, but alumni continue to stay or come back to Switzerland. This results from a tension : Swiss centrality for financial careers and protection against family, political and national uncertainties

Texto completoThe objective of the present thesis is to answer the following research question: What are the concepts and characteristics that identify the internationalization process in Brazilian Universities? To obtain the desired data, an exploratory, qualitative research was developed using a multiple case study approach, conducted with four Brazilian Privately Owned College Institutions. It was employed investigation techniques in document analysis and focused interviews. The results reveal a new internationalization concept and the identification of some characteristic of this process at the researched universities. Results indicate that all studied institutions have in their strategies the creation and structuring of an international office as a basic condition to start an internationalization process to cope with market demands. Regarding teaching and research, the predominant characteristic is the student formation for his or her professionalization, notwithstanding the reduced focus on research. Mobility is the main theme in the internationalization process; therefore, it characterizes a growing tendency of the periodic half year or annual student international exchange. The researched college institutions diverge in relation to payment and credit validation formats. Another common characteristic is that the four researched universities are still in an initial internationalization process
Esta pesquisa tem por objetivo responder ao seguinte problema de pesquisa: Quais os conceitos e características que identificam o processo de internacionalização em Universidades Brasileiras? Para obtenção dos dados desejados foi realizada uma pesquisa exploratória e qualitativa que adotou como estratégia o estudo de caso múltiplo com quatro IES privadas brasileiras. Foram empregadas as técnicas de investigação de análise documental e entrevistas focadas. Os resultados obtidos foram um novo conceito de internacionalização e a identificação de algumas características deste processo nas universidades pesquisadas. As pesquisas indicam que todas as instituições pesquisadas tiveram em sua estratégia a característica de criação e estruturação de um escritório internacional como condição básica para iniciar um processo de internacionalização e adaptação às demandas de mercado. Em relação ao ensino e pesquisa a característica é de preponderância na formação do aluno para atuação profissional e menor foco na pesquisa. A mobilidade é o principal tema nos processos de internacionalização e caracterizam-se por mobilidade discente de periodicidade semestral ou anual, com tendência de crescimento. As IES pesquisadas divergem em relação a forma de validação de créditos e pagamentos. Outra característica comum é que as 04 universidades pesquisadas ainda estão em processo inicial de internacionalização

Texto completoIn recent years, we have observed the development of connected and nomad devices suchas smartphones, tablets or even laptops allowing individuals to use location-based services(LBSs), which personalize the service they offer according to the positions of users, on a dailybasis. Nonetheless, LBSs raise serious privacy issues, which are often not perceived by the endusers. In this thesis, we are interested in the understanding of the privacy risks related to thedissemination and collection of location data. To address this issue, we developed inferenceattacks such as the extraction of points of interest (POI) and their semantics, the predictionof the next location as well as the de-anonymization of mobility traces, based on a mobilitymodel that we have coined as mobility Markov chain. Afterwards, we proposed a classificationof inference attacks in the context of location data based on the objectives of the adversary.In addition, we evaluated the effectiveness of some sanitization measures in limiting the efficiencyof inference attacks. Finally, we have developed a generic platform called GEPETO (forGEoPrivacy Enhancing Toolkit) that can be used to test the developed inference attacks
Maouche, Mohamed. "Protection against re-identification attacks in location privacy". Thesis, Lyon, 2019. http://www.theses.fr/2019LYSEI089.
Texto completoWith the wide propagation of handheld devices, more and more mobile sensors are being used by end users on a daily basis. Those sensors could be leveraged to gather useful mobility data for city planners, business analysts and researches. However, gathering and exploiting mobility data raises many privacy threats. Sensitive information such as one’s home or workplace, hobbies, religious beliefs, political or sexual preferences can be inferred from the gathered data. In the last decade, Location Privacy Protection Mechanisms (LPPMs) have been proposed to protect user data privacy. They alter data mobility to enforce formal guarantees (e.g., k-anonymity or differential privacy), hide sensitive information (e.g., erase points of interests) or act as countermeasures for particular attacks. In this thesis, we focus on the threat of re-identification which aims at re-linking an anonymous mobility trace to the know past mobility of its user. First, we propose re-identification attacks (AP-Attack and ILL-Attack) that find vulnerabilities and stress current state-of-the-art LPPMs to quantify their effectiveness. We also propose a new protection mechanism HMC that uses heat maps to guide the transformation of mobility data to change the behaviour of a user, in order to make her look similar to someone else rather than her past self which preserves her from re-identification attacks. This alteration of mobility trace is constrained with the control of the utility of the data to minimize the distortion in the quality of the analysis realized on this data

Texto completoAs a child, the minor must be protected. When moving across borders, minors are exposed to peculiar problems. These types of situations where several States are involved usually lead to the implementation of private international law. But can we apply the rules of private international law to the protection of the displaced child?This study proposes to clarify the use of this section of the law in achieving a tangible objective. Indeed, the private regulatory evolution of private international law seems to legitimize this aim in granting the subject matter the capacity to protect an interest and, more specifically that which concerns us, the interest of the displaced child.Specifically, this connection should be attributed to the competent authorities and to the law of the child's habitual residence in the event of continuous displacement. In order to understand the focus and integration centre of the displaced minor, the customary residence reflects the axiological system of the minor, that is to say, the focal point of his or her main ties. Of course, in the event of a change in the child's customary residence, the rules inherent to conflict of mobility should be able to justify their intervention in an effort to update the location of the focus and integration centre and, consequently, to the understanding. Thus, in the hypothetical case of temporary displacement, the closest chosen proximity should lead to the subsidiary, exceptional and temporary designation of the competent authorities and to the law of the State in whose territory the child is located.However, the flexibility of our proposals seemed to have lead to sometimes allowing deviations from the normal rules of jurisdiction. This would, however, only be achieved by the acceptance of the judges and the parties concerned.In conclusion, this study proposes to employ the functional use of private international law whereby the sole purpose is to provide children displaced across borders, with solutions that are ready to guarantee them adequate protection despite the complexity of the situation
Cerf, Sophie. "control theory for computing systems : application to big-data cloud services & location privacy protection". Thesis, Université Grenoble Alpes (ComUE), 2019. http://www.theses.fr/2019GREAT024.
Texto completoThis thesis presents an application of Control Theory for Computing Systems. It aims at investigating techniques to build and control efficient, dependable and privacy-preserving computing systems. Ad-hoc service configuration require a high level of expertise which could benefit from automation in many ways. A control algorithm can handle bigger and more complex systems, even when they are extremely sensitive to variations in their environment. However, applying control to computing systems raises several challenges, e.g. no physics governs the applications. On one hand, the mathematical framework provided by control theory can be used to improve automation and robustness of computing systems. Moreover, the control theory provides by definition mathematical guarantees that its objectives will be fulfilled. On the other hand, the specific challenges of such use cases enable to expand the control theory itself. The approach taken in this work is to use two application computing systems: location privacy and cloud control. Those two use-cases are complementary in the nature of their technologies and softwares, their scale and in their end-users.The widespread of mobile devices has fostered the broadcasting and collection of users’ location data. It could be for the user to benefit from a personalized service (e.g. weather forecast or route planning) or for the service provider or any other third party to derive useful information from the mobility databases (e.g. road usage frequency or popularity of places). Indeed, many information can be retrieved from location data, including highly sensitive personal data. To overcome this privacy breach, Location Privacy Protection Mechanisms (LPPMs) have been developed. They are algorithm that modify the user’s mobility data, hopefully to hide some sensitive information. However, those tools are not easily configurable by non experts and are static processes that do not adapt to the user’s mobility. We develop two tools, one for already collected databases and one for online usage, that, by tuning the LPPMs, guarantee to the users objective-driven levels of privacy protection and of service utility preservation. First, we present an automated tool able to choose and configure LPPMs to protect already collected databases while ensuring a trade-off between privacy protection and database processing quality. Second, we present the first formulation of the location privacy challenge in control theory terms (plant and control, disturbance and performance signals), and a feedback controller to serve as a proof of concept. In both cases, design, implementation and validation has been done through experiments using data of real users collected on the field.The surge in data generation of the last decades, the so-called bigdata, has lead to the development of frameworks able to analyze them, such as the well known MapReduce. Advances in computing practices has also settled the cloud paradigms (where low-level resources can be rented to allow the development of higher level application without dealing with consideration such as investment in hardware or maintenance) as premium solution for all kind of users. Ensuring the performances of MapReduce jobs running on clouds is thus a major concern for the big IT companies and their clients. In this work, we develop advanced monitoring techniques of the jobs execution time and the platform availability by tuning the resource cluster size and realizing admission control, in spite of the unpredictable client workload. In order to deal with the non linearities of the MapReduce system, a robust adaptive feedback controller has been designed. To reduce the cluster utilization (leading to massive financial and energetic costs), we present a new event-based triggering mechanism formulation combined with an optimal predictive controller. Evaluation is done on a MapReduce benchmark suite running on a large-scale cluster, and using real jobs workloads

Texto completoLa presente dissertazione parte da una constatazione fin troppo banale, ovvero dal fatto che: " ... Storicamente il mondo delle costruzioni, nella sua accezione più ampia, non si è mai reso ben conto, fino in fondo, dei cambiamenti epocali che hanno caratterizzato i problemi relativi alla sicurezza del lavoro nel corso di questi ultimi decenni ... ". Ora, partendo da questo presupposto così banale quanto nefasto nella sua semplicità e nelle sue implicazioni la ricerca propone una serie di considerazioni che in parte negano tale assunto. Se da una parte è vero che scorrendo gli annuari relativi agli infortuni sul lavoro, dello specifico settore delle costruzioni, ci si accorge che nonostante il tempo sia trascorso, anche con l'emanazione di un gran numero di nuove norme, le cose non sono poi cambiate un granché, dall'altra, analizzando attentamente e con senso maggiormente critico i dati quantitativi a disposizione si evince che, di fatto, il problema "sicurezza" si è, in qualche modo, evoluto nel tempo, ma non in eguale misura rispetto ad altri comparti delle attività produttive. Di fatto, il "cantiere edile" ha delle peculiarità e delle specificità che lo contraddistinguono fortemente da tutte le altre attività produttive specialmente per quanto concerne i rischi, insiti nel continuo evolversi delle situazioni ambientali, estremamente variabili al mutare della vita stessa del cantiere, e per quanto concerne l'importante materia della prevenzione dei rischi d'infortunio sul lavoro. Eppure, come si diceva poc'anzi, nel corso di questi ultimi decenni molti provvedimenti legislativi, specifici per il settore delle costruzioni, si sono susseguiti nel tempo richiedendo il rispetto di un numero sempre crescente di norme prevenzionali e comportamentali, tutte orientate alla tutela della sicurezza dei lavoratori impiegati nei cantieri. Ciò a dimostrare che la semplice emanazione ed applicazione di regole astratte non sono sufficienti da sole a risolvere l'annoso problema della sicurezza negli ambienti di lavoro. Si è quindi reso evidente che il ''problema sicurezza" doveva essere affrontato mediante un nuovo approccio ed efficaci nuove metodologie che richiedessero una innovativa ''presa di coscienza" da parte di tutti gli operatori del settore. Ovvero, in siffatta prospettiva, ci si è resi conto che era necessario far nascere una nuova "cultura della sicurezza" attraverso non solo l'emanazione di norme rivoluzionarie, per il ridisegno dell'intera disciplina in materia, ma anche e soprattutto attraverso la definizione di nuovi soggetti responsabili ai quali assegnare quei delicati e strategici compiti di "costruire", attraverso la collaborazione e con il concorso degli operatori tutti, una sicurezza che sia finalmente "effettiva ed efficace" e non solamente ipotetica e puramente teorica e come tale foriera di oscuri presagi. Ed è in questo contesto che nasce la nuova disciplina quadro per la sicurezza nei cantieri temporanei e mobili, ormai entrata in vigore da diversi anni. Di fatto, il nuovo impianto normativo è stata introdotto nel nostro ordinamento con l'entrata in vigore del famigerato D.Lgs. 494/96, detto anche "Decreto cantieri", che ha finalmente recepito i contenuti della direttiva comunitaria 92/57/CEE del 24 giugno 1992, in materia di "Prescrizioni minime di sicurezza e di salute da attuare nei cantieri temporanei e mobili". Vengono così individuate e analiticamente definite delle nuove figure professionali, alle quali viene richiesta una specifica preparazione e particolari attitudini, che in diversi modi e tempi e con diverso grado di responsabilità sono chiamate a porre concretamente in essere quanto sopra menzionato. Oltre a ciò, al fine di raggiungere tale obiettivo, si è resa palese la necessità di affrontare le tematiche legate alla sicurezza del lavoro in maniera preventiva, ovvero mentre l'opera sta per essere ideata, con il conseguente coinvolgimento di quel soggetto per il quale l'opera viene realizzata: il "committente dei lavori". Tale figura, strategicamente determinante nelle scelte progettuali e storicamente sinora sempre tenuta estranea alle questioni legate alla sicurezza del cantiere, oggi è chiamata a svolgere un compito fondamentale, con la contestuale attribuzione di pesanti responsabilità, per la salvaguardia della salute e dell'integrità fisica dei lavoratori, oltre che nella fase progettuale dell'opera, anche nella fase esecutiva della stessa. Nonostante tutto ciò il "mondo delle costruzioni", fatica non poco ad entrare in quest'ottica e ancor oggi le regole di cui sopra si faceva cenno stentano nel concreto ad essere pienamente ed efficacemente applicate. La dissertazione di che trattasi, quindi, è stata suddivisa in cinque capitoli, oltre alle conclusioni finali, nei quali sono state trattate approfonditamente le tematiche fin qui troppo superficialmente esposte. Nel primo di questi, preceduto da una serie di considerazioni formulate nelle premesse, è stata fatta un'analisi storica riguardante la sicurezza nei cantieri in relazione anche alle norme che nel tempo si sono susseguite. Più nello specifico, per meglio capire quali sono state e quali sono oggi le norme che governano questo particolare settore produttivo, è stata svolta un'analisi storica concernente l'evoluzione normativa in materia di sicurezza del lavoro partendo dai primi timidi tentativi di regolamentazione risalenti già agli inizi del novecento. Sono stati citati, nell'ordine, gli articoli del codice penale, del codice civile e della Costituzione della Repubblica Italiana, concernenti l'argomento, quali primi decisivi passi ancor oggi più che attuali. Sono stati altresì citati i primi provvedimenti legislativi degli anni '50 e '70 con un particolare riguardo alle norme più importanti in materia di prevenzione degli infortuni sul lavoro ancora oggi in vigore e ritenute unanimemente pietre miliari della materia. Ed è così che si è approfondita l'analisi dei singoli provvedimenti legislativi partendo dal D.P.R. 547/1955, passando poi al D.P.R. 164/1956 ed infine al D.P.R. 303/1956, ripeto, tutte norme facenti parte integrante della disciplina organica della sicurezza negli ambienti di lavoro. Le grandi riforme degli anni '90, anch'esse oggetto di attenta analisi, ispirate ed omologate alla forte azione propositiva e dinamica fornita dalla promulgazione di una numerosa serie di Direttive comunitarie, aventi come unico obiettivo dichiarato, da una parte, di omogeneizzare le diverse discipline degli Stati membri in materia di sicurezza ed igiene del lavoro, e dall'altra, aumentare di fatto gli standards di sicurezza in tutti i Paesi, nel ridisegnare completamente la disciplina, pur mantenendo in vigore le precedenti norme di dettaglio ritenute ancora attuali, hanno decisamente contribuito a far nascere una nuova "cultura della sicurezza". Così sono stati approfonditi meglio i vari aspetti legati all'entrata in vigore del D.Lgs. 277/91, del D.Lgs. 626/94, che del "decreto cantieri" ne è il precursore, del D.Lgs.459/96, del D.Lgs. 493/96, ed infine del D.Lgs. 494/96. Più nello specifico, le norme di cui al D.Lgs. 494/96 poi modificate ed integrate dal successivo D.Lgs. 528/99, definite a pieno titolo figlie delle Direttive comunitarie omologhe, rappresentano per loro stessa natura la disciplina quadro del settore di cui si argomenta. Disciplina quadro nel senso che con l'entrata in vigore di questo importante provvedimento legislativo la materia viene completamente ed organicamente rivisitata e, alla stessa stregua, vengono, da un lato, trasferite e meglio specificate talune responsabilità in capo ai vari soggetti e dall'altro, create nuove figure professionali con specifici ruoli e compiti, talora molto gravosi, da assolvere. Tutti aspetti ben evidenziati nel secondo capitolo della dissertazione che tratta, appunto, dei vari aspetti normativi e giuridicostituzionali della disciplina quadro. Sono stati quindi approfonditi importanti temi legati alla sicurezza cosiddetta "infra-aziendale" giustapposta alla cosiddetta "sicurezza coordinata" e posti in corretta relazione ai fattori di rischio "aggiuntivi" ed "interferenziali" caratterizzanti proprio quei luoghi di lavoro ove interagiscono diversi soggetti. Soggetti di cui sono state ampiamente descritte e inquadrate le varie prerogative e le relative responsabilità. Non sono quindi stati trascurati dall'analisi il committente, con le concernenti problematiche relative al trasferimento di responsabilità attraverso lo strumento della "delega di funzioni", il responsabile dei lavori e le altre figure professionali che intervengono nel processo, talune assolutamente inedite ed innovative rispetto al passato. Sono proprio questi soggetti e queste nuove figure professionali, alle quali vengono richieste una specifica preparazione e particolari attitudini, che sono state l'oggetto di quanto trattato nel terzo capitolo del presente lavoro. L'analisi fornita sulle varie figure, che in diversi modi e tempi vengono investite di responsabilità, e la disamina degli obblighi e dei compiti a cui quest'ultime vengono chiamate ad assolvere risulta completata da un utile, quanto mai esplicativo, quadro sanzionatorio applicabile in ordine alle eventuali infrazioni commesse. Allo stesso modo, nel quarto capitolo, si è tentato di fornire una analisi comparata tra appalti pubblici e privati, specificatamente per quanto concerne gli aspetti legati alla sicurezza nei cantieri, alla quale è stata anteposta una necessaria quanto attenta indagine sul complesso mondo degli appalti pubblici e sulla specifica, ancorché variegata, disciplina che lo accompagna ed assiste, sia di livello nazionale che di livello regionale. Infine, un approfondimento è stato dedicato agli aspetti economici e sociali intimamente collegati alla materia in trattazione, anche nel tentativo di contemperare degli aspetti meramente tecnici e giuridici con altri di natura sostanzialmente diversa, in base ai quali si è pervenuti alla considerazione che investire in "sicurezza" rappresenta, paradossalmente, uno dei più potenti strumenti di riduzione globale dei costi, sia dal punto di vista economico che sociale, anche perché agendo sugli aspetti legati alla prevenzione degli infortuni risulta evidente che i vantaggi che ne derivano sono quasi sempre superiori ai costi necessari per generarli. Il quinto capitolo di approfondimento teorico-applicativo è stato dedicato all'analisi dei vari documenti che costituiscono la sicurezza, e più precisamente: i piani di sicurezza e di coordinamento, i piani sostitutivi ed operativi, il diagramma di Gantt o cronoprogramma dei lavori, la notifica preliminare ed il fascicolo dell'opera, che sono stati oggetto, prima, di definizione e, in seguito, di ulteriore specificazione per quanto riguarda gli aspetti concernenti le loro specifiche funzioni ed i loro contenuti L'ultima parte della dissertazione è dedicata alle conclusioni a cui si è pervenuti, in relazione agli argomenti trattati ed alle tematiche che sono state ritenute meritevoli di approfondimento, fornendo, nel contempo, una panoramica di quanto si sta già facendo e quanto debba ancora essere fatto sull'argomento. Infine, segue una indispensabile appendice normativa con riportato il testo del D.Lgs. 494/96 come modificato ed integrato dal successivo D.Lgs. 528/99 e della L. 11 febbraio 1994, n.109, "Legge quadro in materia di lavori pubblici" così come modificata ed integrata dai successivi provvedimenti legislativi.

Texto completoMovable public property shall be understood as the set of personal property placed in a patrimonial legal relationship with public entities. These goods are characterized by their mobility (such as movable private property), that is to say an ability to circulate, physically and legally, a flexibility and fragility medium, favouring the dissociation of their utilities. But the central question remains whether public ownership is still a relevant instrument for understanding this mobility. It turns out that public ownership, when called upon, potentially exerts an effective force of attraction on all movable public property; thus it allows slowing down their circulation. However, once the good’s ownership has been claimed, public property law is not sufficient to monitor the integrity of movable public property. It doesn’t stem their natural crumbling and evaporation. It is even challenged by other legal relationships which, by dissociation of goods’ utilities, and by unbinding ownership and use, lead to question its relevance

Texto completoThe Internet has substantially embraced mobility since last decade. Cellular data network carries majority of Internet mobile access traffic and become the de facto solution of accessing Internet in mobile fashion, while many clean-slate Internet mobility solutions were proposed but none of them has been largely deployed. Internet mobile users increasingly concern more about their privacy as both researches and real-world incidents show leaking of communication and location privacy could lead to serious consequences. Just the communication itself between mobile user and their peer users or websites could leak considerable privacy of mobile user, such as location history, to other parties. Additionally, comparing to ordinary Internet access, connecting through cellular network yet provides equivalent connection stability or longevity. In this research we proposed a novelty paradigm that leverages concurrent far-side proxies to maximize network location privacy protection and minimize interruption and performance penalty brought by mobility.To avoid the deployment feasibility hurdle we also investigated the root causes impeding popularity of existing Internet mobility proposals and proposed guidelines on how to create an economical feasible solution for this goal. Based on these findings we designed a mobility support system offered as a value-added service by mobility service providers and built on elastic infrastructure that leverages various cloud aided designs, to satisfy economic feasibility and explore the architectural trade-offs among service QoS, economic viability, security and privacy.
