A User-Centric Privacy Authorization Model Based on Role and Session in the Context-Aware Home

The seamless combining with context-aware sensors and numerous devices and e-home server will soon become a part of our home environment in the near future. We name it as a context-aware home based on ubiquitous computing concept. This context-aware home reduces participations of users in order to realize a ubiquitous computing and automates various services. Therefore, the risk of privacy violation is higher than that of the general computing environment given user participations. This paper presents a user-centric access control model based on role and session in the context-aware home. Our model provides privacy protection for the users using a range of services of the context-aware home and provides anonymity by joining ID and roles.
