Spatial Domains for the Administration of Location-based Access Control Policies

In the last few years there has been an increasing interest for a novel category of access control models known as location-based or spatially-aware rolebased access control (RBAC) models. Those models advance classical RBAC models in that they regulate the access to sensitive resources based on the position of mobile users. An issue that has not yet been investigated is how to administer spatially-aware access control policies. In this paper we introduce GEO-RBAC Admin, the administration model for the location-based GEO-RBAC model. We discuss the concepts underlying such administrative model and present a language for the specification of GEO-RBAC policies.
