With the development of web services technology, web services have changed from single to composite services. Privacy protection in composite services is becoming an important issue. P3P (platform for privacy preferences) is a privacy policy language which was designed for single web services. It enables service providers to express how they will deal with the privacy information of service consumers. In order to solve the problem that P3P cannot be applied to composite services directly, we propose a method to obtain P3P privacy policies for composite services. In this method, we present the definitions ofPurpose,Recipient, andRetentionelements as well asOptionalandRequiredattributes for P3P policies of composite services. We also provide an instantiation to illustrate the feasibility of the method.
