Texto completoStandards lead to the creation of requirements listings and test verification matrices allow developer and acquirer to assure themselves and each other that the requested system is actually what is being constructed. Further, in the intricacy of the software test description, traceability of test process to the requirement under test is mandated so the acceptance test process can be accomplished in an efficient manner. In the view of the logistician, the maintainability of the software and the repair of fond faults is primary, while these statistics can be gathered by the producer to ultimately enhance the Capability Maturity Module (CMM) rating of the vendor.

Texto completoDie modellgetriebene Softwareentwicklung (MDE) verspricht heutzutage, durch das Verringern der inhärenten Komplexität der klassischen Softwareentwicklung, das Entwickeln von Software zu vereinfachen. Um dies zu erreichen, erhöht MDE das Abstraktions- und Automationsniveau durch die Einbindung domänenspezifischer Modelle (DSMs) und Modelloperationen (z.B. Modelltransformationen oder Codegenerierungen). DSMs sind konform zu domänenspezifischen Modellierungssprachen (DSMLs), die dazu dienen das Abstraktionsniveau der Softwareentwicklung zu erhöhen. Modelloperationen sind essentiell für die Softwareentwicklung da diese den Grad der Automatisierung erhöhen. Dennoch muss MDE mit Komplexitätsdimensionen umgehen die sich grundsätzlich aus der erhöhten sprachlichen und technologischen Heterogenität ergeben. Die erste Komplexitätsdimension ist das Konfigurieren einer Umgebung für MDE. Diese Aktivität setzt sich aus der Implementierung und Selektion von DSMLs sowie Modelloperationen zusammen. Eine solche Aktivität ist gerade durch die Implementierung und Anpassung von Modelloperationen zeitintensiv sowie fehleranfällig. Die zweite Komplexitätsdimension hängt mit der Anwendung von MDE für die eigentliche Softwareentwicklung zusammen. Das Anwenden von MDE ist eine Herausforderung weil eine Menge von heterogenen DSMs, die unterschiedlichen DSMLs unterliegen, erforderlich sind um ein komplexes Softwaresystem zu spezifizieren. Individuelle DSMLs werden verwendet um spezifische Aspekte eines Softwaresystems auf bestimmten Abstraktionsniveaus und aus bestimmten Perspektiven zu beschreiben. Hinzu kommt, dass DSMs sowie DSMLs grundsätzlich nicht unabhängig sind, sondern inhärente Abhängigkeiten besitzen. Diese Abhängigkeiten reflektieren äquivalente Aspekte eines Softwaresystems. Eine Teilmenge dieser Abhängigkeiten reflektieren Anwendungen diverser Modelloperationen, die notwendig sind um den Grad der Automatisierung hoch zu halten. Dies wird erschwert wenn man die erste Komplexitätsdimension hinzuzieht. Aufgrund kontinuierlicher Änderungen der DSMs, müssen alle Arten von Abhängigkeiten, inklusive die Anwendung von Modelloperationen, kontinuierlich verwaltet werden. Dies beinhaltet die Wartung dieser Abhängigkeiten und das sachgerechte (wiederholte) Anwenden von Modelloperationen. Der Beitrag dieser Arbeit ist ein Ansatz, der die Bereiche Traceability und Model Management vereint. Das Erfassen und die automatische Verwaltung von Abhängigkeiten zwischen DSMs unterstützt Traceability, während das (automatische) wiederholte Anwenden von heterogenen Modelloperationen Model Management ermöglicht. Dadurch werden die zuvor erwähnten Herausforderungen der Konfiguration und Anwendung von MDE überwunden. Die negativen Auswirkungen der ersten Komplexitätsdimension können gelindert werden indem Modelloperationen in atomare Einheiten zerlegt werden. Um der implizierten Fragmentierung entgegenzuwirken, erfordert dies allerdings eine nachfolgende Komposition der Modelloperationen. Der Ansatz wird als erweitertes Model Management betrachtet, da ein signifikanter Anteil dieser Arbeit die Kompositionen von heterogenen Modelloperationen behandelt. Unterstützt werden zwei unterschiedliche Arten von Kompositionen. Datenfluss-Kompositionen werden verwendet, um Netzwerke von heterogenen Modelloperationen zu beschreiben, die nur durch das Teilen von Ein- und Ausgabe DSMs komponiert werden. Kontext-Kompositionen bedienen sich eines Konzepts, das von deklarativen Modelltransformationen bekannt ist. Dies ermöglicht die Komposition von unabhängigen Transformationsregeln auf unterschiedlichsten Detailebenen. Die in dieser Arbeit eingeführten Kontext-Kompositionen bieten die Möglichkeit eine Menge von unterschiedlichsten Abhängigkeiten als Kontext für eine Komposition zu verwenden -- unabhängig davon ob diese Abhängigkeit eine Modelloperation repräsentiert. Zusätzlich müssen die Modelloperationen, die komponiert werden, selber keine Kompositionsaspekte implementieren, was deren Wiederverwendbarkeit erhöht. Realisiert wird dieser Ansatz durch einen Formalismus der Executable and Dynamic Hierarchical Megamodel genannt wird und auf der originalen Idee der Megamodelle basiert. Auf Basis dieses Formalismus' sind die Konzepte Traceability (hier Localization) und Model Management (hier Execution) umgesetzt.

Texto completoThis thesis aims at identifying theoretically and concretely how visual analytics can support historians in their social network analysis process. Historical social network analysis is a method to study social relationships between groups of actors (families, institutions, companies, etc.) through a reconstruction of relationships of the past from historical documents, such as marriage acts, migration forms, birth certificates, and censuses. The use of visualization and analytical methods lets social historians explore and describe the social structure shaping those groups while explaining sociological phenomena and individual behaviors through computed network measures. However, the inspection and encoding of the sources leading to a finalized network is intricate and often results in inconsistencies, errors, distortions, and traceability problems, and current visualization tools typically have usability and interpretability issues. For these reasons, social historians are not always able to make thorough historical conclusions: many studies consist of qualitative descriptions of network drawings highlighting the presence of motifs such as cliques, components, bridges, etc. The goal of this thesis is therefore to propose visual analytics tools integrated into the global social historians' workflow, with guided and easy-to-use analysis capabilities. From collaborations with historians, I formalize the workflow of historical network analysis starting at the acquisition of sources to the final visual analysis. By highlighting recurring pitfalls, I point out that tools supporting this process should satisfy traceability, simplicity, and document reality principles to ease bask and forth between the different steps, provide tools easy to manipulate, and not distort the content of sources with modifications and simplifications. To satisfy those properties, I propose to model historical sources into bipartite multivariate dynamic social networks with roles as they provide a good tradeoff of simplicity and expressiveness while modeling explicitly the documents, hence letting users encode, correct, and analyze their data with the same abstraction and tools. I then propose two interactive visual interfaces to manipulate, explore, and analyze this data model, with a focus on usability and interpretability. The first system ComBiNet allows an interactive exploration leveraging the structure, time, localization, and attributes of the data model with the help of coordinated views and a visual query system allowing users to isolate interesting groups and individuals, and compare their position, structures, and properties. It also lets them highlight erroneous and inconsistent annotations directly in the interface. The second system, PK-Clustering, is a concrete proposition to enhance the usability and effectiveness of clustering mechanisms in social network visual analytics systems. It consists in a mixed-initiative clustering interface that let social scientists create meaningful clusters with the help of their prior knowledge, algorithmic consensus, and interactive exploration of the network. Both systems have been designed with continuous feedback from social historians, and aim to increase the traceability, simplicity, and document reality of visual analytics supported historical social network research. I conclude with discussions on the potential merging of both tools, and more globally on research directions towards better integration of visual analytics systems on the whole workflow of social historians. Systems with a focus on those properties---traceability, simplicity, and document reality---can limit the introduction of bias while lowering the requirements for the use of quantitative methods for historians and social scientists which has always been a controversial discussion among practitioners

Texto completoPreservation of information is not a new issue but preservation of digital information has a relatively short history. Since the 60’s when computers began to be used within administration, digital information that has had to be preserved over time.The problem addressed in this research is how to preserve understandable information over time. Information is context dependent, which means that without context it is not possible to use the information. Process is one part of the context. And an important issue when preserving information is then to be able to trace an information
object to the process where in it has been created and managed. Associating information to a particular process creates the possibility of relating information objects to each other and also to the context in which the information has been created and used. The aim of this thesis is to identify and structure factors that can improve the traceability between information and processes over time. A set of factors based on case studies and a set of analytical methods are presented that can improve the traceability over time. These factors have been identified and structured by the use of the Synergy-4 model. They have been identified within four different spheres namely: competence, management, organization/procedure and technology. The factors have further been structured in three different time states namely: creation time, short and middle term and long-term. The research concludes that there are a lot of factors influencing ability to preserve information. Preservation issues include selection of metadata standards, organizational culture, lack of understanding from management and formalization of documents. The conclusion is that if an organization wants to succeed in preserving traceable information they have to build strategies that cover the issues from a range of different angles. This thesis suggests that crucial angles are competence, management, organization/procedure
and technology. Furthermore, the strategies must be in place at the stage of creationof the information objects.

Texto completoPublic administration is using electronic government (e-government) application systems for several years to support their processes more intensive with modern information and communication technology than ever before. This increases and broadens the relationship between law and legislation executed by the administration on the one hand and requirements to e-government application systems used to support administrative execution on the other hand. This relationship is subject matter of pre-requirements specification traceability (pre-RS traceability). This work introduces an approach to pre-RS traceabiliy for e-government application. It combines research efforts and standards (i.e. of World Wide Web Consortium and Object Management Group) from different fields: traceability, semantic web, ontology engineering and model driven software engineering. Using this approach it is possible to add a semantic to elements of law and legislation texts using annotations. Annotation semantics is based on an ontology of public administration execution developed especially for this approach. A mapping from annotated text elements as a special kind of ontology individuals to elements of Unified Modeling Language (UML) is created using the Ontology Definition Metamodel (ODM). This mapping results in a new model type referred to as Pre-Requirements Model (PRM). This model uses elements that exist before requirements are explicitly documented in a requirements specification. Therefore it can be primary used to formalize elements and their relationships in the pre-requirements scope. Through the mapping rules of ODM it keeps a traceable relationship from each model element to its corresponding annotated text elements. PRM can also be used to model and refine elements that are not or not completely derived directly from text of law and legislation. In this work is argued that Model Driven Architecture (MDA) might profit from extending the existing model types Computation Independent Model (CIM), Platform Independent Model (PIM) and Platform Specific Model (PSM) by using a PRM. This extension leads to an Architecture that starts with a pre-requirements viewpoint before any requirements are formalized and documented in models of type CIM. It offers also the opportunity to use model transformation to create an initial CIM from PRM by allying the MOF Query View Transformation standard (QVT). Using QVT ensures the traceability of model transformation because standard enforces recording of traceability information. A Transformation from PRM to CIM creates an initial requirements specification that can be refined using common techniques, methods and tools. To bridge the semantic gap between PRM and CIM the approach follows the pattern of PIM to PSM transformation which uses the Platform Model (PM). Analogues PRM to CIM transformation uses special reference models for e-government developed in the project "E-LoGo" at university of Potsdam. By recoding traces of mapping annotation to elements in PRM and transforming elements of PRM to elements in CIM using reference models continuous pre-RS traceability can be achieved. The approach uses simple Extensible Stylesheet Language Transformations (XSLT) to create a hypertext documentation that links all relevant elements. Navigating along these links makes it possible for example to start with an annotated element of a law text and follow to all resulting requirements in a CIM. Using the opposite direction it is possible to see for each requirement from which text element of a law it is derived or even if there is no relation to law. By integrating the graphical representation of a model element this navigation can even start directly in a UML diagram. This illustrates that the approach offers vertical and horizontal traceability in forward and backward direction. Besides the obvious use cases continuous pre-requirements specification traceability offers in general (i.e. impact analysis on changes of law and legislation, consider context of a requirements when prioritizing them) is also offers the chance to create a feedback on the consequences of a change in law to existing e-government systems. As long as alternatives and the necessary scope in legislative process are still left, a feedback can be used to choose an alternative with less effort or faster implementation. For federal law it is in Germany since 2011 obligatory to make a similar estimation referred to as achievement effort (“Erfüllungsaufwand”). This work contributes to the first step of making a solid estimation of this kind of effort using pre-RS traceability.

Texto completoTillverkare och leverantörer inom techindustrin, som handlar med och drar nytta utav mineraler, är ofta oförmögna att genomföra djupgående företagsgranskningar i sina logistikkedjor, på grund av exempelvis kompetensbrist, vida utspridd information och kedjornas flytande natur. Att säkerställa ifall en produkt har utvunnits på ett hållbart sätt eller huruvida den innehåller konfliktmineraler är i det närmaste omöjligt. Denna studie utforskar blockkedjeteknikens potentiella roll i leverantörskedjor för mineraler, som ett kompletterande verktyg för att genomföra företagsgranskningar. Välgenomförda granskningar bör inkludera fortlöpande statusprotokoll för olika åtgärder gällande social hållbarhet, som identifierar utvinningens påverkan på mänskligt välmående. Så, hur kan en blockkedjelösning för spårbarhet i en leverantörskedja för mineraler bidra till att säkerställa hållbar utvinning? En blockkedja möjliggör spårbarhet av transaktioner genom sin oföränderliga kedjestruktur; samtidigt är kännedom om ursprunget hos en resurs avgörande för att genomföra företagsgranskningar i logistikkedjor. Ett blockkedjenätverk har potential att tillhandahålla information gällande det digitalt registrerade flödet hos en resurs, men informationens validitet gällande dess fysiska och sociala kvaliteter är fortsatt beroende av aktören som registrerar resursen på blockkedjan, vilket leder till ett ofrånkomligt problem gällande gränssnittet mellan den digitala och fysiska världen vid applicering av blockkedjor i leverantörskedjor. Utifrån en litteraturgenomgång och intervjuer med forskare och professionella, så föreslås i denna studie en kravlista att ta hänsyn till ifall blockkedjelösningar ska användas för att understödja hållbar utvinning. Studien visar att en blockkedja på egen hand ej kan säkerställa hållbar utvinning och ger vidare insikt i utmaningar och möjligheter inom industrin, samt diskuterar lämpligheten för potentiella blockkedjelösningar i dessa sammanhang.
Mammadova, Aynur. "Deforestation risk in bovine leather supply chain. Risk assessment through conceptualization, discourse and trade data analysis within the context of Italian-Brazilian leather trade". Doctoral thesis, Università degli studi di Padova, 2019. http://hdl.handle.net/11577/3424866.
Texto completoLarge-scale industrial agricultural production and commodity trade are increasingly linked to deforestation and forest degradation in the tropics. This link is described via the concept of ‘deforestation risk’. Agricultural products whose production or extraction involves deforestation and native vegetation clearing are classified as forest-risk commodities. Beef, soybean, palm oil, and timber - the commodities with deforestation risk - are considered the “big four” of forest-risk commodities. Due to the complexity of global production and trade systems there are commodities that possess the risk of originating from deforested areas without being direct deforestation/forest degradation drivers. This dimension of the risk is either overlooked or held as secondary in the debates about commodity-driven deforestation. Differentiation between commodities with direct causal links and those with the exposure to deforestation in their supply chain has impact on how responsibility and accountability is constructed both through legal measures and self-regulatory voluntary standards. Better conceptualization is needed to approximate the usage of the terms both in grey and academic literature and to achieve science backed policy decisions. By referring to the case of bovine leather (hereinafter just leather) and the case of Brazilian leather production we aim to expand the conceptualization of deforestation risk. We focus on leather for multiple reasons. First, while the role of cattle in driving deforestation in Brazil is subject to increasing public scrutiny, the leather commodity chain largely remains in the shadow. Except for a few leading firms in leather goods, public discussion about transparency across the leather supply chain and associated deforestation risk is mostly absent. Second, leather supply chains are more complex compared to beef and involve many national and international players, including intermediary sellers, tanneries, fashion houses, etc. This creates traceability gaps and complicates identifying deforestation risk along the chain. Third, leather is a commodity with inherently uneven power relations among the actors in the supply chain and with costs and benefits unevenly distributed across the chain. Often considered a waste or by-product to beef meat, actors in the leather supply chain argue to lack important negotiation power to impose their standards and no deforestation conditions upon producers. At the same time, downstream actors of leather supply chain, such as fashion brands, are more susceptible to reputational risks compared to that of beef. While upstream farmers lack resources to adhere to sustainability standards and hardly get any financial compensation for the skin of their cattle, finished leather products are often regarded as luxury products presenting very high price margins for producing/trading brands. This research employs both primary and secondary data. Primary data is mostly qualitative and entails thirty-nine semi-structured, recorded, and transcribed interviews, in the form of both face-to-face and video call interviews conducted during extended field visit to Brazil in May-August 2018. This data is mainly used for the discourse analysis in the second chapter and for interpretative and contextual purposes to analyse the secondary quantitative data in the other chapters. Secondary information consists of extensive literature review, statistical data on annual slaughter, bovine hide/leather registry and annual deforestation, geospatial data on deforestation, slaughterhouse and tannery locations, as well as, trade statistics on Brazilian-Italian leather trade. No specific time frame was chosen to analyse the data and time series for each data set were selected according to availability and the specific requirements of each type of analysis. The results show that bovine leather supply chains possess significant risk of embedded deforestation despite leather not being a primary product of cattle ranching and driver of deforestation. The risk reveals itself in the link with cattle ranching, incomplete supply chain traceability, as well as in interstate and international leather trade. The Brazilian-Italian bovine leather has significant level of embedded deforestation due to intensive trade relations. Different discourses articulate deforestation risk of bovine leather differently and highlight how the storylines of each discourse bring attention both to what is made visible and invisible in relation to sustainability, legitimacy, and fairness. The results emphasise the importance of the role and voice of frontier settlers, by presenting how their storylines inform a political discourse on livelihoods. There is a need for increased public scrutiny of supply chains, including the leather one, and for special attention to unequal power relations and the importance of meaningful inclusion of vulnerable groups and populations. The leather industry and big brands need to be more proactive by sending clear market signals that deforestation and other illegalities are not tolerated. Full coverage and traceability of the supply chain and engagement with the producers is necessary if the industry wants to produce and trade deforestation-free products.

Traceability allows to identify the product’s origin and route, at any time of its production chain, main requirement in normalization processes, certifications and in quality management systems. About food products, where contamination acciddent’s impact involves health damage, traceability allows that the affected lots may be detected and quickly removed from the market with safety, minimizing losses. Besides legal requirements about traceability, the final consumer is looking for having access to informations about food which are being eaten, motivating tecnological solution’s development in this area. The goal of this dissertation is to present the specification of RastroGrão Framework, to traceability of productive grains process. This Framework is based in regulations and rules of quality applied to traceability and in systems of grains traceability, allowing records relative to production’s processes. These records can be changing according to the necessity of each participant agent of production chain. Data to be traced are recorded by the user, not being necessary system maintenance everytime it appears a new requirement to be traced. To the development of Framework was used Java Language to WEB Environment and PostgreSQL Database. The main contribution of this dissertation are related to the benefits offered by the Framework are: i) visibility of informations, which can be accessed through internet, by all the chain agents; ii) integration of all links of the productive chain; and iii) information’s availability to the final consumer through QR-Code, that can be accessed in the internet or printed on the packaging.
A rastreabilidade permite identificar a origem e o percurso de um produto, em qualquer momento de sua cadeia produtiva, requisito fundamental em processos de normalização, certificações e em sistemas de gestão da qualidade. Em se tratando de produtos alimentícios, onde o impacto de acidentes de contaminação envolve riscos a saúde, a rastreabilidade permite que os lotes afetados sejam detectados e retirados do mercado, com rapidez e segurança, minimizando prejuízos. Além das exigências legais em torno da rastreabilidade, o consumidor final está buscando ter acesso às informações sobre os alimentos que estão consumindo, motivando o desenvolvimento de soluções tecnológicas nesta área. O objetivo desta dissertação é apresentar a especificação do Framework RastroGrão, para rastreabilidade do processo produtivo de grãos. Esse Framework está baseado nos regulamentos e normas de qualidade aplicadas à rastreabilidade e em sistemas de rastreabilidade de grãos, permitindo os registros inerentes aos processos de produção. Esses registros podem ser alterados de acordo com a necessidade de cada agente participante da cadeia de produção. Os dados a serem rastreados são registrados pelo próprio usuário, não necessitando de manutenção de sistema cada vez que surge um novo requisito a ser rastreado. Para o desenvolvimento do Framework foi utilizada a Linguagem Java para Ambiente WEB e o Banco de Dados PostgreSQL. As principais contribuições desta dissertação estão relacionadas aos benefícios oferecidos pelo Framework são: i) visibilidade das informações, as quais podem ser acessadas pela internet, por todos os agentes da cadeia; ii) integração de todos os elos da cadeia produtiva, e iii) disponibilização das informações para o consumidor final através de QR-Code, que pode ser acessado na internet ou impresso nas embalagens
Azzi, Rita. "Blockchain Adoption in Healthcare : Toward a Patient Centric Ecosystem". Electronic Thesis or Diss., Institut polytechnique de Paris, 2023. http://www.theses.fr/2023IPPAT053.
Texto completoThe healthcare sector evolves constantly, driven by technological advancement and innovative solutions. From remote patient monitoring to the Internet of Things (IoT), Artificial Intelligence (AI), personalized medicine, mobile health, and electronic records systems, technology has improved patient outcomes and enhanced care delivery. These technologies have shifted the healthcare ecosystem to be more patient-centered, focusing on meeting the patient's needs rather than the needs of the individual organizations within it. However, this transformative shift experienced by the healthcare industry is associated with multiple challenges due to the inherent complexity and fragmentation of the healthcare ecosystem. This dissertation addresses three healthcare ecosystem challenges that significantly impact patients. The first challenge addressed is the problem of counterfeit or falsified drugs that represent a threat to public health, resulting from the vulnerabilities in the pharmaceutical supply chain, notably centralized data management and the lack of transparency. The second challenge addressed is the problem of healthcare data fragmentation that thwarts care coordination and impacts clinical efficiency. This problem results from the dynamic and complex patients' journey in the healthcare system, shaped by their unique health needs and preferences. Patient data are scattered across multiple healthcare organizations within centralized databases and are ruled by policies that hinder data sharing and patients' empowerment over their data. The third challenge addressed is the confidentiality and privacy of healthcare data that, if compromised, shatter the trust relationship between patients and healthcare stakeholders. This challenge results from the healthcare organizations' poor data governance that increases the risk of data breaches and unauthorized access to patient information.The blockchain has emerged as a promising solution to address these critical challenges. It was introduced into the healthcare ecosystem with the promise of enforcing transparency, authentication, security, and trustworthiness. Through comprehensive analysis and case studies, this dissertation assesses the opportunities and addresses the challenges of adopting the blockchain in the healthcare industry. We start with a thorough review of the state of the art covering the blockchain's role in improving supply chain management and enhancing the healthcare delivery chain. Second, we combine theoretical and real-world application studies to develop a guideline that outlines the requirements for building a blockchain-based supply chain. Third, we propose a patient-centric framework that combines blockchain technology with Semantic technologies to help patients manage their health data. Our fourth contribution presents a novel approach to data governance by developing a blockchain-based framework that improves data security and empowers patients to participate actively in their healthcare decisions. In this final contribution, we widen the scope of the proposed framework to include a roadmap for its adoption across diverse domains (banking, education, transportation, and logistics, etc.)

Texto completoThe recent digital transformation of the manufacturing world has resulted in numerous benefits, from higher quality products to enhanced productivity and shorter time to market. In this digital world, data has become a critical element in many critical decisions and processes within and across organizations. Data exchange is now a key process for the organizations' communication, collaboration, and efficiency. Industry 4.0 adoption of modern communication technologies has made this data available and shareable at a quicker rate than we can consume or track it. This speed brings significant challenges such as data interoperability and data traceability, two interdependent challenges that manufacturers face and must understand to adopt the best position to address them. On one hand, data interoperability challenges delay faster innovation and collaboration. The growing volume of data exchange is associated with an increased number of heterogeneous systems that need to communicate with and understand each other. Information standards are a proven solution, yet their long and complex development process impedes them from keeping up with the fast-paced environment they need to support and provide interoperability for, slowing down their adoption. This thesis proposes a transition from predictive to adaptive project management with the use of Agile methods to shorten the development iterations and increase the delivery velocity, increasing standards adoption. While adaptive environments have shown to be a viable solution to align standards with the fast pace of industry innovation, most project requirements management solutions have not evolved to accommodate this change. This thesis also introduces a model to support better requirement elicitation during standards development with increased traceability and visibility. On the other hand, data-driven decisions are exposed to the speed at which tampered data can propagate through organizations and corrupt these decisions. With the mean time to identify (MTTI) and mean time to contain (MTTC) such a threat already close to 300 days, the constant growth of data produced and exchanged will only push the MTTI and MTTC upwards. While digital signatures have already proven their use in identifying such corruption, there is still a need for formal data traceability framework to track data exchange across large and complex networks of organizations to identify and contain the propagation of corrupted data. This thesis analyses existing cybersecurity frameworks, their limitations, and introduces a new standard-based framework, in the form of an extended NIST CSF profile, to prepare against, mitigate, manage, and track data manipulation attacks.
