Title

Query rewriting for access control on semantic web

Language

English

Abstract

Along with describing the web resources with ontology-based metadata to make them machine-understandable, one also needs to carefully protect Semantic Web data from unauthorized access. This paper presents a query rewriting mechanism for access control so as to avoid leakage of sensitive resources in the Semantic Web. We propose to specify the security policies for access restrictions on resources as views declared based on ontologies. Illustrated examples are presented in the paper for explaining the underlying concepts. In addition, bucket-based algorithms are proposed for supporting the query rewriting.
