Blockchain-Based digital identity managementSchneider, Nejc (Avtor) Perko, Igor (Mentor) Pereira, Elisabeth (Komentor) blockchainself-sovereign identitymanagement systemsidentity dataSovrin network.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.[N.
