Abstract :
Role-based access control has established itself as a generalized approach for handling access control in collaboration systems. In a location-aware mobile collaboration environment, users can be restricted to assign roles only when (s)he satisfy some predefined identity and spatio-temporal constraint. To cope with these requirements, we extend the existing RBAC model and propose an extended role-based access control (Ex- RBAC) model capable of expressing identity and spatio- temporal constraints.
