  abstract =     "Securing access to data in location-based services and
                 mobile applications requires the definition of
                 spatially aware access-control systems. Even if some
                 approaches have already been proposed either in the
                 context of geographic database systems or context-aware
                 applications, a comprehensive framework, general and
                 flexible enough to deal with spatial aspects in real
                 mobile applications, is still missing. In this paper,
                 we make one step toward this direction and present
                 GEO-RBAC, an extension of the RBAC model enhanced with
                 spatial-and location-based information. In GEORBAC,
                 spatial entities are used to model objects, user
                 positions, and geographically bounded roles. Roles are
                 activated based on the position of the user. Besides a
                 physical position, obtained from a given mobile
                 terminal or a cellular phone, users are also assigned a
                 logical and device-independent position, representing
                 the feature (the road, the town, the region) in which
                 they are located. To enhance flexibility and
                 reusability, we also introduce the concept of role
                 schema, specifying the name of the role, as well as the
                 type of the role spatial boundary and the granularity
                 of the logical position. We then extend GEO-RBAC to
                 support hierarchies, modeling permission, user, and
                 activation inheritance, and separation of duty
                 constraints. The proposed classes of constraints extend
                 the conventional ones to deal with different
                 granularities (schema/instance level) and spatial
                 information. We conclude the paper with an analysis of
                 several properties concerning the resulting model.",
