A location tracking sensor network is being deployed in several buildings at the University of
Michigan to help explore issues in design of pervasive 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. We provide users with the means
to control distribution of data about them (such as their location information) through the use of
privacy policies. The paper shows how a wide variety of policies can be specified in the system and
points out directions for future work.
