The growing concerns in term of the privacy of data stored in public cloud have restrained the widespread adoption of cloud computing. The traditional method to protect the data privacy is to encrypt data before they are sent to public cloud, but heavy computation is always introduced by this approach, especially for the image and video data, which has much more amount of data than text data. Another way is to take advantage of hybrid cloud by separating the sensitive data from non-sensitive data and storing them in trusted private cloud and un-trusted public cloud respectively. But if we adopt the method directly, all the images and videos containing sensitive data have to be stored in private cloud, which makes this method meaningless. Moreover, the emergence of the Software-Defined Networking (SDN) paradigm, which decouples the control logic from the closed and proprietary implementations of traditional network devices, enables researchers and practitioners to design new innovative network functions and protocols in a much easier, flexible, and more powerful way. The data plane will ask the control plane to update flow rules when the data plane gets new network packets with which it does not know how to deal with, and the control plane will then dynamically deploy and configure flow rules according to the data plane's requests, which makes the whole network could be managed and controlled efficiently. However, this kind of reactive control model could be used by hackers launching Distributed Denial-of-Service (DDoS) attacks by sending large amount of new requests from the data plane to the control plane. For image data, we divide the image is into pieces with equal size to speed up the encryption process, and propose two kinds of method to cut the relationship between the edges. One is to add random noise in each piece, the other is to design a one-to-one mapping function for each piece to map different pixel value into different another one, which cuts off the relationship between pixels as well the edges. Our mapping function is given with a random parameter as inputs to make each piece could randomly choose different mapping. Finally, we shuffle the pieces with another random parameter, which makes the problems recovering the shuffled image to be NP-complete. For video data, we propose two different methods separately for intra frame, I-frame, and inter frame, P-frame, based on their different characteristic. A hybrid selective video encryption scheme for H.264/AVC based on Advanced Encryption Standard (AES) and video data themselves is proposed for I-frame. For each P-slice of P-frame, we only abstract small part of them in private cloud based on the characteristic of intra prediction mode, which efficiently prevents P-frame being decoded. For cloud running with SDN, we propose a framework to keep the controller away from DDoS attack. We first predict the amount of new requests for each switch periodically based on its previous information, and the new requests will be sent to controller if the predicted total amount of new requests is less than the threshold. Otherwise these requests will be directed to the security gate way to check if there is a attack among them. The requests that caused the dramatic decrease of entropy will be filter out by our algorithm, and the rules of these request will be made and sent to controller. The controller will send the rules to each switch to make them direct the flows matching with the rules to honey pot.

Повний текст джерелаPeople who are referred to as data owners in this study, use the Internet for various purposes and one of those is using online services like Gmail, Facebook, Twitter and so on. These online services are offered by organizations which are referred to as data controllers. When data owners use these service provided by data controllers they usually have to agree to the terms and conditions which gives data controllers indemnity against any privacy issues that may be raised by the data owner. Data controllers are then free to share that data with any other organizations, referred to as third parties. Though data controllers are protected from lawsuits it does not necessarily mean they are free of any act that may be considered a privacy violation by the data owner. This thesis aims to arrive at a design proposition using the design science research paradigm for a middleware extension, specifically focused on the Tomcat server which is a servlet engine running on the JVM. The design proposition proposes a client side annotation based API to be used by developers to specify classes which will carry data outside the scope of the data controller's system to a third party system, the specified classes will then have code weaved in that will communicate with a Privacy Engine component that will determine based on data owner's preferences if their data should be shared or not. The output of this study is a privacy enhancing platform that comprises of three components the client side annotation based API used by developers, an extension to Tomcat and finally a Privacy Engine.

Повний текст джерела“Cloud computing”, eller “molntjänster” som blivit den vanligaste svenska översättningen, har stor potential. Molntjänster kan tillhandahålla exaktden datakraft som efterfrågas, nästan oavsett hur stor den är; dvs. molntjäns-ter möjliggör vad som brukar kallas för “elastic computing”. Effekterna avmolntjänster är revolutionerande inom många områden av datoranvändning.Jämfört med tidigare metoder för databehandling ger molntjänster mångafördelar; exempelvis tillgänglighet av automatiserade verktyg för att monte-ra, ansluta, konfigurera och re-konfigurera virtuella resurser “allt efter behov”(“on-demand”). Molntjänster gör det med andra ord mycket lättare för or-ganisationer att uppfylla sina målsättningar. Men det paradigmskifte, sominförandet av molntjänster innebär, skapar även säkerhetsproblem och förutsätter noggranna integritetsbedömningar. Hur bevaras det ömsesidiga förtro-endet, hur hanteras ansvarsutkrävandet, vid minskade kontrollmöjligheter tillföljd av delad information? Följaktligen behövs molnplattformar som är såkonstruerade att de kan hantera känslig information. Det krävs tekniska ochorganisatoriska hinder för att minimera risken för dataintrång, dataintrångsom kan resultera i enormt kostsamma skador såväl ekonomiskt som policymässigt. Molntjänster kan innehålla känslig information från många olikaområden och domäner. Hälsodata är ett typiskt exempel på sådan information. Det är uppenbart att de flesta människor vill att data relaterade tillderas hälsa ska vara skyddad. Så den ökade användningen av molntjänster påsenare år har medfört att kraven på integritets- och dataskydd har skärptsför att skydda individer mot övervakning och dataintrång. Exempel på skyd-dande lagstiftning är “EU Data Protection Directive” (DPD) och “US HealthInsurance Portability and Accountability Act” (HIPAA), vilka båda kräverskydd av privatlivet och bevarandet av integritet vid hantering av informa-tion som kan identifiera individer. Det har gjorts stora insatser för att utvecklafler mekanismer för att öka dataintegriteten och därmed göra molntjänsternasäkrare. Exempel på detta är; kryptering, “trusted platform modules”, säker“multi-party computing”, homomorfisk kryptering, anonymisering, container-och “sandlåde”-tekniker.Men hur man korrekt ska skapa användbara, integritetsbevarande moln-tjänster för helt säker behandling av känsliga data är fortfarande i väsentligaavseenden ett olöst problem på grund av två stora forskningsutmaningar. Fördet första: Existerande integritets- och dataskydds-lagar kräver transparensoch noggrann granskning av dataanvändningen. För det andra: Bristande kän-nedom om en rad kommande och redan existerande säkerhetslösningar för att skapa effektiva molntjänster.Denna avhandling fokuserar på utformning och utveckling av system ochmetoder för att hantera känsliga data i molntjänster på lämpligaste sätt.Målet med de framlagda lösningarna är att svara de integritetskrav som ställsi redan gällande lagstiftning, som har som uttalad målsättning att skyddaindividers integritet vid användning av molntjänster.Vi börjar med att ge en överblick av de viktigaste begreppen i molntjäns-ter, för att därefter identifiera problem som behöver lösas för säker databe-handling vid användning av molntjänster. Avhandlingen fortsätter sedan med en beskrivning av bakgrundsmaterial och en sammanfattning av befintligasäkerhets- och integritets-lösningar inom molntjänster.Vårt främsta bidrag är en ny metod för att simulera integritetshot vidanvändning av molntjänster, en metod som kan användas till att identifierade integritetskrav som överensstämmer med gällande dataskyddslagar. Vårmetod används sedan för att föreslå ett ramverk som möter de integritetskravsom ställs för att hantera data inom området “genomik”. Genomik handlari korthet om hälsodata avseende arvsmassan (DNA) hos enskilda individer.Vårt andra större bidrag är ett system för att bevara integriteten vid publice-ring av biologiska provdata. Systemet har fördelen att kunna sammankopplaflera olika uppsättningar med data. Avhandlingen fortsätter med att före-slå och beskriva ett system kallat ScaBIA, ett integritetsbevarande systemför hjärnbildsanalyser processade via molntjänster. Avhandlingens avslutan-de kapitel beskriver ett nytt sätt för kvantifiering och minimering av risk vid“kernel exploitation” (“utnyttjande av kärnan”). Denna nya ansats är ävenett bidrag till utvecklingen av ett nytt system för (Call interposition referencemonitor for Lind - the dual layer sandbox).

In this point is the growth of data is high every day in sector like the micro financial, resulting from transactions and operations carried out with these companies on a daily basis. Appropriate management of the personal data privacy policies is therefore necessary because, otherwise, it will comply with personal data protection laws and regulations and let take quality information for decision-making and process improvement. The present study proposes a personal data protection maturity model based on international standards of privacy and information security, which also reveals personal data protection capabilities in organizations. Finally, the study proposes a diagnostic and tracing assessment tool that was carried out for five companies in the micro financial sector and the obtained results were analyzed to validate the model and to help in success of data protection initiatives.

Повний текст джерелаIm Rahmen der Dissertation wurde ein Framework für die Durchsetzung von Richtlinien zum Schutz privater Daten geschaffen, welches darauf setzt, dass diese Richtlinien oder Policies direkt von den Eigentümern der Daten erstellt werden und automatisiert durchsetzbar sind. Der Schutz privater Daten ist ein sehr wichtiges Thema im Bereich der elektronischen Kommunikation, welches durch die fortschreitende Gerätevernetzung und die Verfügbarkeit und Nutzung privater Daten in Onlinediensten noch an Bedeutung gewinnt. In der Vergangenheit wurden verschiedene Techniken für den Schutz privater Daten entwickelt: so genannte Privacy Enhancing Technologies. Viele dieser Technologien arbeiten nach dem Prinzip der Datensparsamkeit und der Anonymisierung und stehen damit der modernen Netznutzung in Sozialen Medien entgegen. Das führt zu der Situation, dass private Daten umfassend verteilt und genutzt werden, ohne dass der Datenbesitzer gezielte Kontrolle über die Verteilung und Nutzung seiner privaten Daten ausüben kann. Existierende richtlinienbasiert Datenschutztechniken gehen in der Regel davon aus, dass der Nutzer und nicht der Eigentümer der Daten die Richtlinien für den Umgang mit privaten Daten vorgibt. Dieser Ansatz vereinfacht das Management und die Durchsetzung der Zugriffsbeschränkungen für den Datennutzer, lässt dem Datenbesitzer aber nur die Alternative den Richtlinien des Datennutzers zuzustimmen, oder keine Daten weiterzugeben. Es war daher unser Ansatz die Interessen des Datenbesitzers durch die Möglichkeit der Formulierung eigener Richtlinien zu stärken. Das dabei verwendete Modell zur Zugriffskontrolle wird auch als Owner-Retained Access Control (ORAC) bezeichnet und wurde 1990 von McCollum u.a. formuliert. Das Grundprinzip dieses Modells besteht darin, dass die Autorität über Zugriffsentscheidungen stets beim Urheber der Daten verbleibt. Aus diesem Ansatz ergeben sich zwei Herausforderungen. Zum einen muss der Besitzer der Daten, der Data Owner, in die Lage versetzt werden, aussagekräftige und korrekte Richtlinien für den Umgang mit seinen Daten formulieren zu können. Da es sich dabei um normale Computernutzer handelt, muss davon ausgegangen werden, dass diese Personen auch Fehler bei der Richtlinienerstellung machen. Wir haben dieses Problem dadurch gelöst, dass wir die Datenschutzrichtlinien in drei separate Bereiche mit unterschiedlicher Priorität aufteilen. Der Bereich mit der niedrigsten Priorität definiert grundlegende Schutzeigenschaften. Der Dateneigentümer kann diese Eigenschaften durch eigene Regeln mittlerer Priorität überschrieben. Darüber hinaus sorgt ein Bereich mit Sicherheitsrichtlinien hoher Priorität dafür, dass bestimmte Zugriffsrechte immer gewahrt bleiben. Die zweite Herausforderung besteht in der gezielten Kommunikation der Richtlinien und deren Durchsetzung gegenüber dem Datennutzer (auch als Data User bezeichnet). Um die Richtlinien dem Datennutzer bekannt zu machen, verwenden wir so genannte Sticky Policies. Das bedeutet, dass wir die Richtlinien über eine geeignete Kodierung an die zu schützenden Daten anhängen, so dass jederzeit darauf Bezug genommen werden kann und auch bei der Verteilung der Daten die Datenschutzanforderungen der Besitzer erhalten bleiben. Für die Durchsetzung der Richtlinien auf dem System des Datennutzers haben wir zwei verschiedene Ansätze entwickelt. Wir haben einen so genannten Reference Monitor entwickelt, welcher jeglichen Zugriff auf die privaten Daten kontrolliert und anhand der in der Sticky Policy gespeicherten Regeln entscheidet, ob der Datennutzer den Zugriff auf diese Daten erhält oder nicht. Dieser Reference Monitor wurde zum einen als Client-seitigen Lösung implementiert, die auf dem Sicherheitskonzept der Programmiersprache Java aufsetzt. Zum anderen wurde auch eine Lösung für Server entwickelt, welche mit Hilfe der Aspekt-orientierten Programmierung den Zugriff auf bestimmte Methoden eines Programms kontrollieren kann. In dem Client-seitigen Referenzmonitor werden Privacy Policies in Java Permissions übersetzt und automatisiert durch den Java Security Manager gegenüber beliebigen Applikationen durchgesetzt. Da dieser Ansatz beim Zugriff auf Daten mit anderer Privacy Policy den Neustart der Applikation erfordert, wurde für den Server-seitigen Referenzmonitor ein anderer Ansatz gewählt. Mit Hilfe der Java Reflection API und Methoden der Aspektorientierten Programmierung gelang es Datenzugriffe in existierenden Applikationen abzufangen und erst nach Prüfung der Datenschutzrichtlinie den Zugriff zuzulassen oder zu verbieten. Beide Lösungen wurden auf ihre Leistungsfähigkeit getestet und stellen eine Erweiterung der bisher bekannten Techniken zum Schutz privater Daten dar.

Повний текст джерелаInternet of Things (IoT) enheter har blivit vanligt förekommande i hem vilket gör deras säkerhet och integritet allt viktigare. Det har tidigare visats att användare av IoT i hemmet kan utgöra ett hot mot sig själva om de saknar kunskap om enheterna och kännedom om potentiella hot. För att undersöka hur användarnas vanor kring säkerhet och integitet kan förbättras är det först nödvändigt att utforska de nuvarande vanorna och vad som påverkar dessa. Detta undersöks i tio intervjuer som visar att vanorna främst påverkas av bekvämlighet, motivation och ansträngningen som krävs av användaren. Utifrån dessa insikter föreslås det att fysisk interaktion används som ett komplement till digitala lösningar för att förbättra vanorna kring säkerhet och integritet. Genom att ha ett fysiskt objekt som på ett enkelt sätt kan förmedla enheternas nuvarande status och är lika tillgängligt för alla medlemmar i ett hushåll kan säkerhet och integritet bli mer uppnåeligt för alla användare, oavsett deras nivå av kunskap och erfarenhet.

Повний текст джерелаThe emergence of personal mobile devices, with communication and positioning features, is leading to new use cases and personalized services. However, they imply a significant collection of personal data and therefore require appropriate security solutions. Indeed, users are not always aware of the personal and sensitive information that can be inferred from their use. The main objective of this thesis is to show how cryptographic mechanisms and data anonymization techniques can reconcile privacy, security requirements and utility of the service provided. In the first part, we study keyed-verification anonymous credentials which guarantee the anonymity of users with respect to a given service provider: a user proves that she is granted access to its services without revealing any additional information. We introduce new such primitives that offer different properties and are of independent interest. We use these constructions to design three privacy-preserving systems: a keyed-verification anonymous credentials system, a coercion-resistant electronic voting scheme and an electronic payment system. Each of these solutions is practical and proven secure. Indeed, for two of these contributions, implementations on SIM cards have been carried out. Nevertheless, some kinds of services still require using or storing personal data for compliance with a legal obligation or for the provision of the service. In the second part, we study how to preserve users' privacy in such services. To this end, we propose an anonymization process for mobility traces based on differential privacy. It allows us to provide anonymous databases by limiting the added noise. Such databases can then be exploited for scientific, economic or societal purposes, for instance

Повний текст джерелаPassenger Name Record access permits authorities to have additional data that could identify individuals requiring more questioning prior to border control clearance. This data does not cause in itself privacy issues other than perhaps the potential retention and manipulation of information that Border Control Authorities may acquire. In essence, bilateral agreements between governments should be sought in order to protect national legislation.
The common goal of the airline industry is to ensure safe and efficient air transport. API and PNR should be viewed as formalities that can facilitate border control clearance and prevent the entrance of potentially high-risk individuals.

Doctoral thesis, Stockholm University, Department of Computer and Systems Sciences (together with KTH), 2008. http://urn.kb.se/resolve?urn=urn:nbn:se:su:diva-7407.
Повний текст джерелаIn healthcare, patient information is a critical factor. The right information at the right time is a necessity in order to provide the best possible care for a patient. Patient information must also be protected from unauthorized access in order to protect patient privacy. It is furthermore common for patients to visit more than one healthcare provider, which implies a need for cross border healthcare and continuity in the patient process.
This thesis is focused on information security in healthcare when patient information has to be managed and communicated between various healthcare actors and organizations. The work takes a practical approach with a set of investigations from different perspectives and with different professionals involved. Problems and needs have been identified, and a set of guidelines and recommendations has been suggested and developed in order to improve patient safety as well as patient privacy.
The results show that a comprehensive view of the entire area concerning patient information management between different healthcare actors is missing. Healthcare, as well as patient processes, have to be analyzed in order to gather knowledge needed for secure patient information management.
Furthermore, the results clearly show that there are deficiencies both at the technical and the administrative level of security in all investigated healthcare organizations.
The main contribution areas are: an increased understanding of information security by elaborating on the administrative part of information security, the identification of information security problems and needs in cross border healthcare, and a set of guidelines and recommendations in order to advance information security measures in healthcare.

Повний текст джерелаIn this work, a case study was made on one company that is working with IT. The study was made to see how an IT company mitigates and handles the problem that employees use their private cloud storage to store work related information. A survey was sent to three different departments at the company to examine what employees think about private cloud storage and work related information and how and if it differs between different departments. One interview was also made with one informant from the same company to compare with the results from the survey. A second interview with another company was also made to validate the result from the first interview.The results from the survey showed that employees do store or have stored work related information in their private cloud storage, despite that the company policies forbid it. One of the departments that the survey was sent to was the information security team. It can be assumed that employees that work with information security have better understanding about security regarding information and how it should be stored. Despite that did the results show that the information security team was the department that used private cloud storage the most, compared to the other departments. The results from the interviews shows that the companies at least have policies on how and where the employees are allowed to store work related information. One company in particular works really hard and continuously to educate and enlighten its employees to take great care when dealing with work related information.

Повний текст джерелаIT Systeme für Medizin und Gesundheitswesen sind ein komplexes und spannendes Feld. Auf der einen Seite stehen eine Vielzahl an Verbesserungen und Arbeitserleichterungen, die Computer zum medizinischen Alltag beitragen können. Einige Behandlungen, Diagnoseverfahren und organisatorische Aufgaben wurden durch Computer überhaupt erst möglich. Auf der anderen Seite gibt es eine Vielzahl an Fakturen, die Computerbenutzung im Gesundheitswesen erschweren und ihre Entwicklung zu einer herausfordernden, sogar frustrierenden Aufgabe machen können. Diese Faktoren sind nicht ausschließlich technischer Natur, sondern auch auf soziale und ökonomische Gegebenheiten zurückzuführen. Dieser Report beschreibt einige Besondenderheiten von IT Systemen im Gesundheitswesen, mit speziellem Fokus auf gesetzliche Rahmenbedingungen, Standards und Sicherheit.

Повний текст джерелаMånga mobilapplikationer har möjlighet att samla in och dela användarspecifik information, utöver den väsentliga datahanteringen. Det här problemet möjliggörs genom dålig applikationsdesign och felaktig implementering. Bristen på säkerhet och integritet i en applikation är därför kritisk, eftersom spridning av känslig och personlig information kan orsaka både fysisk och emotionell skada, om den delas med obehöriga personer. Denna avhandling undersöker hur man konfidentiellt kan överföra användarinformation på ett sätt som tillåter användaren av mobilapplikationen att förbli både anonym och icke spårbar. För att uppnå detta kommer användaren först att behöva autentisera sig till en tredje part, vilket förser användaren med slumpmässigt genererade tecken eller med ett certifikat. Användaren kan sedan använda dessa till att kommunicera med servern, vilket kommer att göras över ett Tor-nätverk. Slutligen när anslutningen upprättats, kommer WiFi-detaljerna att skickas över periodvis till servern, detta sker automatiskt utan att användaren initierar överföringen. Resultatet visar att det är möjligt att skapa en anslutning både med ett certifikat eller med slumpmässiga tecken. Att generera de slumpmässiga tecknen tog mindre tid jämfört med certifikaten, däremot tog certifikaten mindre tid att verifiera än tecknen. Detta resulterade i att de båda metoderna hade en jämn prestanda om man ser över hela systemet. Resultatet visar vidare att det implementeringen av Tor fungerar då det är möjligt för systemet att dölja den verkliga IPadressen och att istället tillhandahålla en slumpmässig IP-adress. Kommunikationen genom Tor gör dock systemet långsammare, vilket är kostnaden för att förbättra användarens integritet och uppnå anonymitet. Sammanfattningsvis visar denna avhandling att genom att kombinera korrekt implementering och bra applikationsdesign kan man förbättra säkerheten i applikationen och därmed skydda användarnas integritet.

Повний текст джерелаSupplier Impersonation Fraud (SIF) is a kind of fraud occuring in a Business-To-Business context (B2B), where a fraudster impersonates a supplier in order to trigger an illegitimate payment from a company. Most of the exisiting systems focus solely on a single, "intra-company" approach in order to detect such kind of fraud. However, the companies are part of an ecosystem where multiple agents interacts, and such interaction hav yet to be integrated as a part of the existing detection techniques. In this thesis we propose to use state-of-the-art techniques in Machine Learning in order to build a detection system for such frauds, based on the elaboration of a model using historical transactions from both the targeted companies and the relevant other companies in the ecosystem (contextual data). We perform detection of anomalous transactions when significant change in the payment behavior of a company is detected. Two ML-based systems are proposed in this work: ProbaSIF and GraphSIF. ProbaSIF uses a probabilistic approach (urn model) in order to asert the probability of occurrence of the account used in the transaction in order to assert its legitimacy. We use this approach to assert the differences yielded by the integration of contextual data to the analysis. GraphSIF uses a graph-based approach to model the interaction between client and supplier companies as graphs, and then uses these graph as training data in a Self-Organizing Map-Clustering model. The distance between a new transaction and the center of the cluster is used to detect changes in the behavior of a client company. These two systems are compared with a real-life fraud detection system in order to assert their performance
