Context-Aware Security model for Social Network Service

Abstract

The number of smart phone-users is rapidly growing due to the recent increase in wireless Internet usage, the development of a variety of applications, the activation of social networks, and so on. The smart phone has the benefits of mobility and convenience, but has the serious security problems. To utilize social network services in the smart phone, a flexible integrated authentication and access control facility is strongly needed. To solve these problems, we suggest a context-aware single sign-on and access control system using context-awareness, integrated authentication, access control, and OSGi service platform in the smart phone environment. In addition, to handle diverse contexts properly and to determine the appropriate security level, we use Fuzzy Logic and MAUT (Multi-Attribute Utility Theory). And also we try to verify a security system whose properties are flexible and convenient through a typical scenario in the smart phone environment. We could provide flexible and secure seamless security service by user context in the smart phone environment using the proposed system.
