The current thesis extends research in the area of multiple social identities and identity conflict by focusing on both intergroup and intraindividual process underlying structures of identities, namely, religious, ethnic, and societal (national) identifications. In addition, it examined the influence of political trust, and perceived discrimination the relationship between ethnic and societal identification for disadvantaged ethnic groups in Turkey. Two studies were conducted to evaluate the process of identity organization both inter group and in group. While, the first study addresses intergroup differentiations of these identities, second study focused on intraindividual process of these identities&#039 / structure. Supporting hypothesis stemming from Social Identity Theory and Optimal Distinctiveness Theory, political trust and perceived discrimination have roles of mediation in the relationship ethnic and societal identification, by contrast with secular and religious identities in the relationship. Results were discussed for their implications to politic context of the Turkey.

This thesis deals with digital identity wallets as digital identification means, through a legal and technical perspective, within the field of legal informatics. The 3rd of July 2021 the European Commission presented a proposal for a regulation of the European Parliament and of the Council amending Regulation (EU) No 910/2014 as regards establishing a framework for a European Digital identity, also known as the eIDAS II-regulation. The eIDAS II-regulation is at this moment being negotiated on EU-level and has not yet been adopted. In the eIDAS II-regulation the digital identity wallets were presented. These wallets en-able citizens and other residents to authenticate, and share electronic documents and identification data, with a relying party. The purpose of the digital identity wallets is to create a harmonized identification solution that will function within all member states of the EU. The thesis will concentrate on the relationship between the legal aspects of the eIDAS II-regulation and the technical solutions presented in the regulation. The eIDAS II-regulation covers a vast variety of legal and technical solutions, however the thesis will only focus on the electronic identification, authentication, and the sharing of electronic documents through the wallet. Furthermore, the thesis will analyse which data can be stored in the wallet according to the eIDAS II-regulation and what legal and technical solutions are proposed to enable shar-ing, and controlling the accuracy, of the data. The relationship between eIDAS II-regulation and GDPR will be discussed and analysed in the end of the thesis. This discussion gives the reader an understanding of how the regulations will integrate with each other and how eIDAS II-regulation is affected by the GDPR. The conclusion of the thesis is that the eIDAS II-regulation, thus the digital identity wallets, is a step in the right direction to create a harmonized regulation for digital identities, however there are certain legal problems that should be ad-dressed to make the digital identity wallets a secure and user-friendly solution. These legal problems with the digital identity wallets could be solved with the right technical specifications. Some of these technical specifications will be pre-sented and discussed in the thesis.

In recent years, state governments, exemplified by Mississippi, have significantly expanded their online service offerings to reduce costs and improve efficiency. However, this shift has led to challenges in managing digital identities effectively, with multiple fragmented solutions in use. This paper proposes a Self-Sovereign Identity (SSI) framework based on distributed ledger technology. SSI grants individuals control over their digital identities, enhancing privacy and security without relying on a centralized authority. The contributions of this research include increased efficiency, improved privacy and security, enhanced user satisfaction, and reduced costs in state government digital identity management. The paper provides background on digital identity management in the public sector, discusses existing practices, presents the SSI framework as a solution, and outlines potential future research areas.

In today’s centralized identity systems, large companies control and store user datain a centralized manner, which poses a risk to users’ privacy and personal data. Self-sovereign identity (SSI) decentralizes digital identity management and gives individu-als full control over which personal data is shared and with whom. Furthermore, SSIenables verifiable credentials, allowing companies, authorities and individuals to buildnetworks of trust among themselves. This thesis discusses SSI, as well as a project whereSSI is practically applied in a mobile software application project for the distribution ofdigital drink tickets. The goal of the project is to develop a prototype to demonstratehow SSI can be applied in a general application, that involves issuing a verifiable cre-dential in the form of a drink ticket. To realize the project goal, an application has beendeveloped in React Native, where several frameworks for SSI have been studied. ”AriesCloud Agent Python” (ACA-Py) has been integrated with a REST API to provide SSIfunctionality to the project. The project has resulted in a working mobile applicationthat can issue and verify digital drink tickets, stored in the digital wallet application ofthe ticket holder. Minimal personal data is shared with the application, and only withthe exclusive approval of the ticket holder. The result confirms the potential of SSI fordecentralized identity management. / I dagens centraliserade identitetssystem är det stora teknikföretag som lagrar och kon-trollerar användardata, vilket medför en risk för användarnas integritet och personligadata. ”Self-sovereign identity” (SSI) decentraliserar digitala identiteter och ger indivi-den full kontroll över vilka personliga data som delas och till vem. Vidare möjliggörSSI verifierbara legitimationer, där förtroendenätverk byggs mellan företag, myndig-heter och individer. Denna uppsats avhandlar SSI, samt ett projekt där SSI appliceratspraktiskt i en mobilapplikation för distribution av digitala dryckesbiljetter. Målet medprojektet är att utveckla en prototyp för att visa hur SSI kan appliceras på en generellapplikation som innebär utgivande av en verifierbar legitimation i form av en dryckesbil-jett. För att realisera målet har en applikation utvecklats i React Native, där flera ramverkför SSI har studerats. ”Aries Cloud Agent Python” (ACA-Py) har integrerats genomREST API för att tillhandahålla SSI-funktionalitet till projektet. Projektet har resulterati en fungerande mobilapplikation som kan utfärda och verifiera digitala dryckesbiljetter,som lagras på en biljettinnehavares digitala plånboksapplikation. Minimal personligdata delas med mobilapplikationen och med innehavarens exklusiva tillstånd. Resultatetbekräftar potentialen av SSI för decentraliserad digital identitetshantering.

Blockchain technology emerged as a potent tool for revolutionizing energy systems, offering secure transactions and efficient resource management. Blockchain offers transparency by enabling decentralized transactions. Despite adopting blockchainbased solutions, some cybersecurity issues persist in Decentralized Renewable Energy Marketplaces (DREMs). Specifically, data privacy, security, and verifiability remain a concern for prosumers and grid operators. To address such issues, several blockchainbased solutions utilize technologies such as Self-Sovereign Identities (SSIs), Digital Machine Identities (DMIs), and Zero-knowledge Proofs (ZKPs). In this work, we first review the literature to gain insight into cybersecurity issues within DREMs addressed using blockchain technology. Based on our review, we conceptualize a framework that leverages SSIs, DMIs, and ZKPs to address these issues. This work-in-progress shows the potential of these technologies to enhance security, privacy, and trust in decentralized energy transactions, paving the way for more resilient and efficient energy systems.

Volunteering - one of the topics which are still present in the society, as it can be perceived as a unique instrument to solve social challenges or organizing society with its specific conditions. The topic of my diploma thesis, based on the grounded theory method, is the process of building and maintaining the relationship of the volunteer to their voluntary work from the volunteers' perspective. I was curious as to what circumstances or limits accompany the forming of such a relationship in the social context and if certain "prototypes" can be found, which would differ in negotiating their role to their surroundings. In my thesis, I focus exclusively on those volunteers who have been given the "Křesadlo" award for the volunteer of the year, which provides the framework of this relationship. I would like to use my results to enrich the knowledge of volunteering's image, which could be used both on the academic field and when working with volunteers. Keywords: civic sector, volunteering, self-perspective, role, identity, "looking-glass self", norm, defence mechanisms, information management, Křesadlo.

This thesis explores high-end and bespoke menswear, tailoring and fashion, asking the question - why do some men choose to spend large sums of money to have clothes made for them? Using tailors and high-end menswear as a lens, this thesis unpacks how men construct their notion of self in the digital and terrestrial worlds through the clothes that they wear and the identities they perform. Based on twelve months' terrestrial fieldwork in London and twenty-four months' concurrent digital fieldwork with Instagram, this thesis examines notions of dress, performance and the individual across a multi-dimensional fieldsite set within a blended digital and terrestrial landscape. The fieldwork comprised visiting and interviewing tailors, and observing inside their workshops and at their fashion shows. In addition, the analyst-as-client built relationships with tailors, and constructed a digital self within Instagram through the publication of self-portraits and images of clothing. This thesis is presented in four chapters, flanked by an Introduction and Conclusion. These chapters move from an exploration of terrestrial research in the first two, to an analysis of digital research in the latter two. Five major motifs emerge in this thesis: the importance of the anthropology of clothing and adornment within western society; the nature of the individual in a digitised world; the difficulty in conducting western-centric fieldwork without an element of digital analysis; a methodological restructuring of digital anthropology; and the idea that a digital self can acquire agency. This thesis employs a pioneering blended methodology which brings together the fields of digital anthropology, visual anthropology and material culture to question how selves are constructed in a rapidly changing and increasingly digitised modernity. In conclusion, the thesis argues that individuals construct multiple digital selves and a sense of identity (around the notion of 'authentic individualism') that is illusory.

The electronic identification regulation, eIDAS, and its trusted service providers are currently based on technologies that have been used for decades. The eIDAS and many others in the security industry have shown interest in newer technologies such as distributed ledgers and blockchain. This research looks into the current eIDAS regulation, its plans for future work, and how the current trusted systems could benefit from introducing blockchain into the solutions. Looking at new technologies is of importance to move forward but also making solutions more secure for the user with for example Self-Sovereign Identity solutions. The research was conducted through a literature review followed by interviews. A number of themes were identified to answer the research question. The findings were that blockchain is a viable technology to use but only if used in the right cases. A better understanding and knowledge of the technology is needed for new implementation to succeed and should not be rushed due to the hype of blockchain technology. / Se bif. fil
