ABSTRACT

The Conventional Role-based Access Control (RBAC) systems evaluate access permissions depending on the identity/role of the users. However, this approach does not incorporate semantic information concerned to users, which could have an impact on access decisions. The basic idea of this paper is to use ontological approach to enable target users to have access to heterogeneous sources of information with intricate semantic relations in educational domain. Here, we proposed user-profile based policy approach in which user profile represented in ontological format so as to meet the semantic relations among different users, and between data objects, so as to enables expressing much more finegrained access control policies. This work aims at creating a user profile ontology that incorporates concepts and properties used to model the user profile. We have developed ontology to realize the framework and need to demonstrate the framework through considering university administrative system as a case study.
