Abstract: In order to overcome the shortcomings of focusing on the user functional requirements and insufficient user privacy protection in Web service, this paper proposes a method based on privacy domain ontology inference to protect user privacy. Firstly, this paper analyzes and describes the privacy domain frame, builds the ontology of privacy domain. Secondly, this paper transforms the user privacy preference into the rules based on SWRL (semantic Web rule language), and reasons on the privacy domain ontology with the inference engine, to examine whether the privacy policy of Web service satisfies user privacy preference or not. The experimental results show that this method can prevent user privacy from illegal disclosure and protect user privacy effectively.
