Security in the Semantic Web using OWL

Information assurance, security, and privacy have moved from narrow topics of interest to information system designers to become critical issues of fundamental importance to society. This opens up new requirements and opportunities for novel approaches. Meeting this challenge requires to advance the theory and practice of security, privacy, and trust of Web-based applications and to provide declarative policy representation languages and ontologies together with algorithms to reason about policies. This paper summarizes an ontological approach to enhancing the Semantic Web with security.
