N2 - As online services are moving from the single service to the composite service paradigm, privacy is becoming an important issue due to the amount of user data being collected and stored. The Platform for Privacy Preferences (P3P) was defined to provide privacy protection by enabling services to express their privacy practices, which in turn helps users decide whether to use the services or not. However, P3P was designed for the single service model, bringing some challenges when employing it with composite services. Moreover the P3P language may lead to misinterpretation by P3P user agents due to its flexibility and may have internal semantic inconsistencies due to a lack of clear semantics. Therefore, we enhance P3P to be able to support composite services, propose a formal semantic for P3P to preserve semantic consistency, and also define combining methods to obtain the privacy policies of composite services.
