Abstract

Centralized identity management systems are most commonly used. However, they pose certain threats to identity owners using them. Most of these problems revolve around users not being in control of their data. Self-sovereign identity seeks to aid this issue by putting the user in control. The research goal is to find out whether decentralized networks implementation in the domain of identity management can prove beneficial for the identity owners. This research addresses the following questions: • How is the user data managed on centralized servers and how can it be managed in a decentralized environment? • What are the blockchain features that could benefit the domain of digital identity management? • Can the blockchain-based solutions fulfill the requirements of SSI as well as GDPR regulations? • What new challenges do they bring and why has a massive adaptation of blockchain technology beyond the field of cryptocurrencies not yet occurred? Previous academic research and industry reports show the massive potential of Blockchain technology. However, there are only a few examples of how to implement this technology to overcome the barriers (Wadhwa, 2019). Blockchain offers immutability, which can be very valuable for certain purposes. However, it may not be an ideal solution for storing personal data. To offer a comprehensive solution, our use-case combines both centralized and decentralized data storage to protect the user data.

Secondary abstract:	Za upravljanje digitalne identitete se najpogosteje uporabljajo centralizirani sistemi. Vendar pa predstavljajo določene grožnje lastnikom identitet, ki jih uporabljajo. Večina teh težav se nanaša na to, da uporabniki ne nadzorujejo svojih podatkov. Samouverena identiteta si prizadeva tako, da uporabnika postavi v nadzor. Cilj raziskave je ugotoviti, ali se lahko decentralizirano omrežje na področju upravljanja identitete izkaže za koristno za lastnike identitete. Ta raziskava obravnava naslednja vprašanja: • Kako se upravljajo podatki uporabnikov na centraliziranem strežniku in kako se lahko upravljajo v decentraliziranem okolju? • Katere so funkcije blockchaina, ki bi lahko koristijona področju upravljanja digitalne identitete? • Ali lahko rešitve, ki temeljijo na blockchainu, izpolnjujejo zahteve SSI in predpisov GDPR? • Kakšne nove izzive prinašajo in zakaj se množična uporaba tehnologije blockchain izven polja kripto valut še ne dogaja? Prejšnja študijska dokomentacija ter poročila industrije kažejo na ogromen potencial tehnologije Blockchain. Vendar pa obstaja le nekaj primerov, kako to tehnologijo uporabiti kljub njenim oviram (Wadhwa, 2019). Blockchain ponuja nespremenljivost, ki je za določene primere lahko zelo uporabna, vendar morda ni idealna rešitev za shranjevanje osebnih podatkov. Da bi ponudili celovito rešitev, raziskan primer uporabe združuje tako centralizirano kot decentralizirano shranjevanje podatkov za zaščito uporabniških identitet.
