Privacy enhancing service architectures

Following from privacy requirements, new architecture solutions for personalized services are expected to emerge. This paper proposes a conceptual framework for designing privacy enabling service architectures, with a special emphasis on the mobile domain. The treatment of the subject is based on the principle of separating identity and profile information. Basic building blocks such as Identity Broker, Profile Broker, Contract Broker and Authenticator are identified and then put together in different ways resulting in variations on the architecture theme.
