This standard defines the data access management for identity relationships. With fine-grained identities for users, artificial intelligence (AI), sensors, and smart devices, data processing and management generate data upon relationships, which provides requirements for authorization, authentication, and access control across systems and entities. Data privacy and protection are involved in the scope of the identity relationship framework. This standard also defines a series of extendable interfaces in ID-based relationship interoperation scenario, to dock third-party utility components like compliance and regulation.
