Abstract

Although RDF ontologies are expressed based on XML syntax, existing methods to protect XML documents are not suitable for securing RDF ontologies. The graph style and inference feature of RDF ontologies demands new methods for access control. Driven by this goal, this paper proposes a query-oriented model for RDF ontology access control. The model adopts the concept of ontology view to rewrite user queries. In our approach, ontology views define accessible ontology concepts and instances a user can visit, and enables a controlled inference capability for the user. The design of the views guarantees that the views are free of conflict. Based on that, the paper describes algorithms for rewriting queries according to different views, and provides a system architecture along with an implemented prototype. In the evaluation, the system exhibits a promising result in terms of effectiveness and soundness.
