Specifying an Access Control Model for Ontologies for the Semantic Web

摘要

Security and privacy are important components of the Semantic Web; the need for research in this area is widely recognized. In this paper we propose a model that regulates access control on ontologies developed for the Semantic Web. Based on the Role Graph Model, our work models the ontology resources as directed, acyclic graphs, incorporating the basic features of the OWL Lite language. We also show how the privileges are propagated and how we can use constraints to deny access to resources in the Semantic Web, an environment where information can be easily accessed through logic inferences.
