摘　　要：身份是一个人所有属性与行为的集合,随着互联网的普及用户身份已经逐渐变得数字化和网络化。数字身份的发展经历了三个特色鲜明的阶段,近年来基于区块链、分布式账本等技术自主身份概念的出现再次深刻影响着数字身份体系发展的路径与模式。自主身份通过在传输协议、技术方案、交互模式以及治理框架方面的变化对传统的数字身份架构进行了颠覆性的改变。因此,对数字身份各发展阶段中核心要素、重要概念的理解以及自主身份出现所带来的改变与其关键要素的清晰认识是预判未来发展的关键。Identity is a collection of all the attributes and behaviors of an entity.With the popularization of Internet,the identity of user has gradually become digitized and networked.The development of digital identity has experienced three distinct stages.In recent years,the advent of self-sovereign identity based on blockchain and distributed ledger technology has affected the development path and mode of digital identity.The self-sovereign identity has made great changes in transmission protocols,technical solutions,interaction modes,and governance frameworks.Therefore,an understanding of the core elements and concepts in separate development stages of digital identity,and the great changes that self-sovereign has brought about are the keys to predicting digital identity development direction.
