Access Control Model Based on RDB Security Policy for OWL Ontology.

Most of information has been storing and managing in relational databases and there are many researches to store OWL ontologies. In this situation, a study on efficient access control model using relational security model is required. The paper proposes a novel access control model for OWL ontologies in relational database systems. The access control is realized through evaluating queries against an OWL data view. On one hand, the OWL data view prevents the sensitive information revealed to unauthorized users. On the other hand it considers the inference ability of users. An empirical study verifies the effectiveness of our approach. [ABSTRACT FROM AUTHOR]
