摘要
Embodiments of the present specification provide methods, apparatuses, devices and systems for backtracking a service behavior. The method includes the following: an identity management system receives an authorization request sent by a service device, where the authorization request is sent based on a service processing request sent by a client device, and the authorization request includes behavior data of an operational behavior of a first user in the client device corresponding to a service to be processed, and authorization information on an operation permission for the behavior data granted by the first user to the service device; if it is determined that the authorization information satisfies a predetermined authorization condition, a first verifiable claim is generated based on the behavior data, the authorization information, first digital identity information of the first user, and second digital identity information of the service device; and the first verifiable claim is saved to a blockchain, such that a supervision organization, when granted an access permission of the first verifiable claim, backtracks the operational behavior of the first user corresponding to the service to be processed based on the first verifiable claim in the blockchain.
