In this paper we will describe how we model personal data in smart environments, which are user adaptive systems. Personal services in such smart environments can access user data by a consistent interface of our user modelling system. Considering inter-home mobility (i.e. users moving across multiple smart environments), the user model is flexible in the sense that it can dynamically deal with users entering or leaving a smart environment. Applying anonymous credentials and pseudonymity in combination with role-based access control, we can protect the privacy of users while protecting the environments against malicious users.
