Context Based Access Control System in Android Smarthones

Android users do not have control over the application capabilities once the applications have been granted the requested privileges upon installation. In many cases, however, whether an application may get a privilege depends on the specific user context and thus we need a context-based access control mechanism by which privileges can be dynamically granted or revoked to applications based on the specific context of the user. Here such a system is implemented in android smartphones. Keywords— Context-based access control, smartphone devices, security and privacy, policies, mobile applications
