A security E-government model based on service-oriented architecture

Internet-based E-government has become a new work model of government departments. But due to heterogeneous and autonomous between different business systems, there are barriers in E-government systems when they are interoperating. To eliminate information silos, building a unified information-sharing platform is a necessary choice for the work of the government´s information. This paper studies service-oriented application integration for E-government system and proposes a security model based on identity authentication.
