An Unified Identity Providing Model of Heterogeneous Resource

Existing identity providing models are generally user-oriented or service provider-oriented, which can hardly meet the requirements of integration for heterogeneous resources of enterprise. This paper presents a unified identity providing model for accessing to heterogeneous resources: providing resource identity, identity mapping from heterogeneous resources identity to unified identity, and also providing identity providing interface for application software developing. Unified identity shields the differences of identity information among resources in heterogeneous environment, which makes users get the ability to access resources with one unified identity.
