Abstract: A digital object identifier (DOI) display request is received. A service type of a service corresponding to the display request is determined. Basic user information of a first user and identity type information corresponding to the service type is determined based on the service type and stored calibration information, where the identity type information is pre-authenticated to ensure validity based on a validity period associated with the identity type information. A DOI of the first user is generated based on the basic user information and the identity type information. The DOI is displayed for a second user to perform service processing based on the basic user information and the identity type information in the DOI.
