Secure identity management for pseudo-anonymous service access

In this paper, we propose an architecture to enable service providers personalise services in a pervasive environment, while minimising risks to users’ privacy.

A trust-based approach supports decisions about accepting personas. We describe a prototype implementation and performance evaluations.8 page(s
