Hierarchical Domains for Decentralized Administration of Spatially-Aware RBAC Systems

Emerging models for context-aware role-based access control pose challenging requirements over policy administration. In this paper we address the issues raised by the decentralized administration of a spatially-aware access control model in a mobile setting. We present in particular GEO-RBAC Admin, the administration model for the GEORBAC model. The model is grounded on the notion of hierarchy of spatial domains where a spatial domain is an entity which collects objects based on organizational and spatial proximity criteria.
