Blockchain-Based Identity Management: A Survey From the Enterprise and Ecosystem Perspective
Michael Kuperberg · IEEE Transactions on Engineering Management · 2019
Identity management is a core building block for the majority of software solutions and landscapes. Competing with existing identity-managing solutions, blockchain-based concepts and products have evolved in the context of verified claims and self-sovereign identities. The contribution of this paper is a systematic, criteria-driven survey of the solutions and technologies for this growing field and their comparison with the capabilities of established solutions. By including an extensive set of requirements covering ecosystem aspects, end-user functionality, mobility and overhead aspects, compliance/liability, EU regulations, standardization, and integration, this paper shows the highlights and the deficits of a wide array of solutions.
