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 (i.e. self-sovereign identity). In this paper, we provide an in-depth review of existing blockchain-based identity management papers and patents published between May 2017 and January 2020. Based on the analysis of the literature, we identify potential research gaps and opportunities, which will hopefully help inform future research agenda.
摘要：身份管理方案通常被用于促进数字身份管理和诸如认证等操作，并且在现实世界的应用程序中身份管理方案也被广泛使用。近年来，有人尝试使用基于区块链的身份管理解决方案，这将允许用户控制自己的身份(例如自我主权身份)。在本文中，我们深入回顾了2017年5月至2020年1月间发表的基于区块链的身份管理的论文和专利。基于对文献的分析，我们明确了潜在的研究差距和机会，这将有希望帮助指导未来的研究议程。
