In today's pervasive computing environment, access control exploiting spatial and temporal constraints has become imperative for information security. This paper suggests a framework to extend X-GTRBAC to include Generalized Spatio Temporal Role Based Access Control (GSTRBAC) spatial constraint construction and enforcement. This allows X-GTRBAC to exploit topological relationship between locations and provides it with formalism to construct rich spatial constraints. The extension provides X-GTRBAC with spatial role enabling, spatial role activation, spatial user role assignment and spatial role permission assignment capability. Since X-GTRBAC can be deployed across a variety of environments, such as web or heterogeneous, our contribution regarding spatial extension of X-GTRBAC could extend the use of spatial contextual parameters in these areas efficiently.
