ABSTRACT
In multiple data sources environment where open access is to be provided to the users not known to the system, the credential based access control has emerged as a suitable approach for achieving security on shared data [22,23,28,29,31]. Mediation techniques have been developed for data integration that provide a single unified view of the multiple data sources to the user[1,2,3,4,5,6,7,18]. For enforcing common access policy across the available data sources and enabling controlled access on data at local levels, appropriate multilevel access control policy is also required. In this paper, we propose a credential based mediator architecture to achieve multilevel access control and data integration in open access environment. To realize the multilevel access policy a credential transfer protocol has been proposed to accomplish the transfer of credentials and extracting attribute values associated with them.
