Participatory sensing is becoming a valuable paradigm, enabling a variety of novel applications built on mobile networks and smart devices. However, this trend brings several challenges, including the need for software platforms to manage interactions between participants and applications, with a number of constraints. One such critical requirement is participant privacy. In this paper, the authors examine the problem of privacy-preserving spatial task assignment in coordinated participatory sensing when the participants do not share their exact location due to privacy concerns.
