User Controlled Privacy in Participatory Sensing

Most of the sensor network applications in military and civilian use are surreptitious. If these are used for the benefit of society in addition to the individual needs a new set of applications can be developed. This paper describes infrastructure monitoring based on collaboration between sensor networks. The solution provides a reputation based hybrid network where collaborative trust is established based on referrals (opinions). Depending on the trust, the information is exchanged between one entity and another with different authorization levels. The outcome of the paper is collaborative data collection with privacy levels controlled by individual users.
