Abstract [Objective] A centralized identity authentication model is raised to solve user identity management problem. [Context] In the National Public Culture Digital Platform, the identity authenticcation needs to consider the characters of the topological structure of the platform and the autonomous of the users from member libraries. [Methods] This model uses an implicit or explicit global identity and mapping relations of automomous identity in order to unify the autonomous identity of the member libraries. [Results] By this model, users don't need to remember multiple identities, member libraries can share users information and realize user-centered. New member libraries can join easily. [Conclusions] This model has certain feasibility, but it still has some problems such as the efficiency, identity disambiguation and security. It should be test and adjust when being implemented.
