Credential Based Mediator Architecture for Access Control and Data Integration in Multiple Data Sources Environment

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]
