One important technical strand of PACTMAN is to explore the use of cloudlets to support privacy mediation. This builds on prior work by a team that includes members of the consortium on privacy mediators for the IoT. The approach involves interposing a locally-controlled software component called a privacy mediator on every raw sensor stream in a pervasive environment. In PACTMAN we are exploring how privacy mediators can be made to work in a dynamic pervasive environment in which users move between physical spaces and privacy mediators must be dynamically instantiated.

Working with a visiting researcher from the University of Stuttgart we have created a prototype architecture and are now in the process of creating a testbed within the context of a smart meeting room.
