Uniform identity authentication system based on ESB in heterogeneous environment

In enterprises and schools, information systems are heterogeneous customarily in operating system, architecture and program language because created time and requirement is different. The self-governed identity authentication and user management lead to differ identity, redundancy information, self-governed system and bad security. This paper integrates independent user management module and authentication module into uniform platform with uniform data exchange standard and interface standard. Using identity management mechanism based on certificate, the uniform identity authentication system based on ESB can make the best use of existing resource to avoid redundant data and reduce program logic effectively. The uniform access control mechanism can enhance security greatly.
