Abstract
Privacy has been a hot topic in research for several years. A lot of different approaches to protect privacy have been proposed recently. Among these there are several tools for negotiation of privacy contracts. In this paper we present our privacy negotiation framework called “The Privacy Advocate”. It consists of three main parts: the policy evaluation unit, the signature unit and the preferences. In addition, our framework supports an interface for negotiation strategies, so that they are independent of the framework. The preferences can be expressed with a combination of P3P and APPEL. The tests we executed using a state of the art PDA clearly indicate that our framework can be used on mobile devices. The completion of a successful negotiation usually takes about 2 sec. including message transfer via an 802.11b wireless link. This involves multiple evaluations of proposals. Each of them is done in less than 250 msec.
