Identity Manage Interoperation Based on OpenID

In order to extend the trust domain that user locates, a new identity manage framework based on OpenID standards is designed to build a contact mechanism for different identity providers. It is composed of two OpenID providers and one service provider. In order to obey the OpenID standards, two proxy web applications are designed to check the validate results from OpenID providers and build contact between two of them. By this means, different OpenID providers can share user's authentication result among them and users can use a uniform identity to get more services controlled by different identity providers. The framework can evidently benefit the development of e-business.
