Privacy and 4G Services: Who Do You Trust?

Ih this paper we address the conflicting requirements where privacy constraints restrict the sharing of information whereas innovative applications, prosecution and prevention require it. We propose a distributed identity management architecture featuring a network-based agent that protects the end-user privacy as much as reasonable and feasible, and yet show how this architecture supports personalised, contect-aware services. We argue that ultimately the issues on end-user privacy boil down to one question: Who do you trust?
