摘要	Currently the Location Based Services (LBS) tend to be more large-scale, distribute and open, which brings up new challenges to the design of spatially aware access control models. Nowadays location based access control models encounter difficulties in both the flexibility of expression, and the scalability and efficiency of the policy management. To address these challenges, in this paper we propose a spatial extension to RBAC model towards large-scale distributed LBS applications. This model defines spatial context, presents the concepts of the parameterized spatial permission and the parameterized spatial role, and implementation architecture. This model enables the definition of spatial authorizations directly to a group of objects which greatly reduces the management cost in large distributed LBS applications. © 2010 IEEE.
