The emerging next generation Web technologies offer tremendous opportunities for automating information management in a variety of application domains including office tasks, travel, and digital government. One of the main challenges facing effective automation is privacy. Verifying the correct usage of collected personal data is a major concern for both individuals and organizations. In this paper, we present a framework for reasoning about privacy models including provider’s privacy policies and user’s privacy preferences. More specifically, we use a Description Logic (DL) based notation to specify privacy abstractions. We provide a formalization of matching user’s privacy preferences against provider’s privacy policies using DLs’ reasoning mechanisms. We have implemented a Privacy Match Engine(PME) which is based on RACER.
