Design of user information profiling for consolidated authentication in N-screen environment

There has been an increase in the services and contents based on heterogeneous multiple media in the wake of the emergence of various smart devices. However, it is difficult to share the services and contents because the smart devices adopt independent OS. HTML5 has come under the limelight which provides the interoperability and can solve such a problem. Nonetheless, the standardization for HTML5 has yet to be completed, making it difficult to achieve the integrated authentication for safe use of services. This paper presents the user profile design method for the integrated authentication within the service based on HTML5. We intend to discuss the measure which enables the integrated management of personal information within the heterogeneous devices using the designed integrated user profile information and can help provide the authentication by phase depending on the selection of user.
