A social relation aware semantic access control

Abstract

Social relations are often used to identify an individual. In the digital world, such relations can be exploited to provide controlled access to private or community contents. This paper proposes an access control model that employs the social relations. Semantic technologies are used for formal specification of the model. The semantic access control model is composed of a knowledge base and access policies. The Web Ontology Language represents the knowledge base and the access policies are expressed through semantic rules. Execution of rules derives the access authorization decisions that state which user can access which contents with a specific privilege. The paper provides a detail evaluation of the proposed access control model.
