Web Services will soon handle users’ private information. They’ll need to provide privacy guarantees to prevent this delicate information from ending up in the wrong hands. More generally, Web Services will need to reason about their users’ policies that specify who can access private information and under what conditions. We propose a more fine-grained security markup of service parameters in OWL-S. We extend our previous work with annotations about the security and privacy policies of services. We express these annotations in Rei, a logic-based language that lets you define rules and constraints over domain-specific ontologies. Our work aims to provide security and policy annotations for OWL-S service descriptions and enforcement by extending the OWL-S Matchmaker for policy matching and the OWL-S Virtual Machine (VM) with policy enforcement and security mechanisms.
