Benefits of a blockchain-based identity management system

Abstract

Identity management solutions are generally designed to facilitate the management of digital identities and operations such as authentication, and have been widely used in real-world applications. In recent years, there have been attempts to introduce blockchain-based identity management solutions, which allow the user to take over control of his/her own identity. In this paper, we provide an in-depth review of existing blockchain-based identity management papers. Based on the analysis of the literature, we identify potential research gaps and opportunities, which will hopefully help inform future research agenda.
