Executive Summary

An important approach for handling user privacy in ubiquitous or pervasive systems is identity management, in which the user has a number of different virtual identities that conceal his/her real identity. One extension of the basic approach identifies the private data needed by services and uses the notion of a privacy policy to determine what access should be granted to private data by a service. This can then be used to determine an appropriate virtual identity. However, this is fairly complex and difficult for a na?ve user to set up and control.
