Participatory sensing is an emerging computing paradigm that enables the distributed collection of data by self-selected participants. It allows the increasing number of mobile phone users to share local knowledge acquired by their sensor-equipped devices (e.g., to monitor temperature, pollution level, or consumer pricing information). While research initiatives and prototypes proliferate, their real-world impact is often bounded to comprehensive user participation. If users have no incentive, or feel that their privacy might be endangered, it is likely that they will not participate. In this paper, the authors focus on privacy protection in participatory sensing and introduce a suitable privacy-enhanced infrastructure.
