Identity Management Based On P 3 P Workshop

Identity management is a powerful mechanism to enhance user-privacy. In this paper we will examine the idea of an identity management system built atop of an anonymouscommunication network. First, we will develop some basic approaches to realize identity management, and we will introduce the Platform for Privacy Preferences Project (P3P) as a standard for exchanging personal data in the World Wide Web. After discussing the feasibility of using P3P as a basis, we will outline some possibilities for designing an identity management system using P3P. For this purpose, other building blocks, especially considering the representation of different kinds of pseudonyms as the core of an identity management system, are described. Finally, we will sketch possible future developments of identity managers.
