Authorization and Privacy for Semantic Web Services

, , , , , and

In this paper we address security of semantic Web services that are declaratively described in OWL-S. We propose ontologies to annotate OWL-S input and output parameters with respect to their security characteristics, including encryption and digital signatures. Moreover, we propose to incorporate privacy and authentication policies into OWL-S descriptions and requester profiles. We designed and implemented algorithms to check policy compliance and propose to integrate them in the service selection process of the OWL-S MatchMaker.
