Privacy - The forgotten challenge in sensor and distributed systems

Privacy is a right that is granted by law and decree to all citizens of Europe and to the registered organisations they work, play or congregate through. The role of sensor networks in general, and wireless sensor networks in particular, in maintaining the privacy of users is considerable, but unfortunately very largely not addressed or not understood. The paper introduces on-going work in FP7 project i-Tour and in the world of standards at ETSI on the means to exchange privacy assertions across distributed networks such that the original consent is maintained even when new actors are introduced to the system.
