Designing a Publish-Subscribe Substrate for Privacy/Security in Pervasive Environments

The emergence of a multitude of technologies for tracking locations is leading to the design of pervasive location-tracking environments. Managing privacy is expected to be a significant concern for acceptance of such pervasive environments. This paper outlines an initial design of a publish-subscribe communication substrate for controlled distribution of sensor data. We describe our prototype as well as a privacy-aware location-tracking application built on top of the system. The focus of this paper is on policy management so as to provide means for allowing users to control distribution of data tagged with their ID to other users and services
