Generic Access Control Model and Semantic Mapping Between Heterogeneous Policies

Abstract

This article aims to ensure a dynamic set up of access control policies across collaborating organizations where these organizations adopt heterogeneous access control models. To attain this objective, this contribution started with a survey on existing access control models, and their specificities on collaboration. Based on this survey, it remains that the topic on access control collaboration still open despite the efforts made. Therefore, in this article a generic representation of access control concepts is proposed. This generic representation considers the process of semantic mapping between policies of heterogeneous access control systems. In this fact an ontology-based semantic mapping is proposed. This mapping has the advantage to optimize the administrators' involvement by combining linguistic-based and upper-ontology based matching techniques with a user-based constraint strategy for ontology matching.
