Privacy Preserving in Participatory Sensing

Deepika Nair | Bhuvaneswari Raju

Abstract: The ubiquity of the various cheap embedded sensors on mobile devices; for example cameras; microphones; accelerometers; and so on; is enabling the emergence of participatory sensing applications. While participatory sensing can benefit the individuals and communities greatly; the collection and analysis of the participators location and trajectory data may jeopardize their privacy. However; the existing proposals mostly focus on participators location privacy; and few are done on participators trajectory privacy. The effective analysis on trajectories that contain spatial-temporal history information will reveal participators whereabouts and the relevant personal privacy.
