Abstract :
In location-based access control systems, the location of subjects is a relevant parameter in access control decisions. Those systems however fail in controlling the location of subjects along the period of use of the objects and this can lead to security breaches. To ensure a stronger protection of objects, a continuous control over the movement of subjectsis thus needed. To address this requirement, we have developed GEO-RBAC_C a location-based access control model supporting continuous usage control capabilities. In the paper,we first present the basic concepts of the model and then discuss how the continuous control can be actually enforced.
