Self-sovereign Identity promises to give users control of their own data, and has the potential to foster advancements in terms of personal data privacy. Self-sovereign concepts can also be applied to other entities, such as datasets and devices. Systems adopting this paradigm will be decentralised, with messages passing between multiple actors, both human and representing other entities, in order to issue and request credentials necessary to meet individual and collective goals. Such systems are complex, and build upon social and technical interactions and behaviours. Modelling self-sovereign identity systems seeks to provide stakeholders and software architects with tools to enable them to communicate effectively, and lead to effective and well-regarded system designs and implementations. This paper draws upon research from Actor-based Modelling to guide a way forward in modelling self-sovereign systems, and reports early success in utilising the iStar 2.0 framework to provide a representation of a birth registration case study.

走向自主身份系统的建模框架

自我主权身份承诺让用户控制自己的数据，并有可能促进个人数据隐私方面的进步。自主权概念也可以应用于其他实体，例如数据集和设备。采用这种范式的系统将是去中心化的，消息在多个参与者（人类和代表其他实体）之间传递，以便颁发和请求满足个人和集体目标所需的凭证。这种系统很复杂，建立在社会和技术互动和行为之上。自我主权身份系统建模旨在为利益相关者和软件架构师提供工具，使他们能够有效沟通，并导致有效且广受好评的系统设计和实现。
