To solve the problems of unified identity authentication between heterogeneous application systems that emerged in the procedure of informatization construction. The paper presents a 3-tier architecture solution that contains user tier, unified authentication tier and application system tier to realize unified identity authentication between legacy system and new application system. For legacy systems, the paper presents a method of double authentication that users firstly log on unified identity authentication system for unified identity validation, then securely transmit authenticated unified identity information and simulate the authentication progress via the authentication mechanism of legacy systems for permission distributing.
