PRIVACY-AWARE DATA PROVIDING WEB SERVICES COMPOSITION

Web services are increasingly used to promote data sharing in collaborative environments such as eBusiness, eHealth, eEnterprise, etc. They facilitate data integration and interoperability across autonomous independent information systems in the collaboration environments. Many mediation solutions were proposed for data integration using Web services. Unfortunately privacy aspects were not addressed in these solutions. In this paper, we proposed a framework for privacy-preserving data integration based on Web services. Our proposal is a centralized access control mechanism allowing for the specification and enforcement of privacy rules in Web services composition based on domain ontologies.
