On the Design of a Tool for Controlling Privacy in the WWW

Concerns about users' privacy are currently attracting signi cant attention. Users usually do not approve of someone mining their actions and habits while they use the Web. On the other hand, having some information about the user's behavior is essential for providing personalized services. Thus, there is a clear demand for mechanisms that allow users to control their privacy without relying on the visited site's policies. In this paper we propose a tool that tells the user the level of privacy maintained throughout his/her interaction with a given site. By using our tool, the user can become aware of privacy violations and may use privacy preservation mechanisms.
