STRBAC - An approach towards spatio-temporal role-based access control

The rapid emergence of GPS enabled devices, sensors and mobile equipment in commercial as well as government or-ganizations has led to considerable research in time- and location-based access control schemes. Location-based ac-cess policies enhance the security of an application by re-stricting access to an object only from specified locations. On the other hand, temporal constraints provide granular-ity in security features and also limit damage to an ap-plication to a specific time interval (e.g. when staff are present to respond if necessary). This paper introduces a novel approach to location- and time-based access control mechanism using Role-Based Access Control (RBAC). We believe that it is well-suited for organizations that require time- and location-based access control over static or mo-bile objects
