Efficient Enforcement of Action-Aware Purpose-Based Access Control within RDBMS - Coimbatore

ABSTRACT:
Among the variety of access control models proposed for database management systems (DBMSs) a key role is covered by the purpose-based access control model, which, while enforcing access control, also achieves basic privacy preservation. We believe that DBMSs could greatly take benefit from the integration of an enhanced purposed based model supporting highly customized and efficient access control. Therefore, in this paper we propose a purpose-based model that supports action-aware policy specification and a related efficient enforcement framework to be integrated into relational DBMSs. The experimental evaluations we have performed show the feasibility and efficiency of the proposed framework.
