The growth in popularity of hand-held mobile devices has fuelled research exploring how to harness the collective abilities of sensors attached to these devices. One area of development has been urban sensing, which explores building a crowd-sourced wireless sensor network using consumer mobile devices. Urban sensing participants use their devices to capture information about their surroundings to contribute to an urban sensing system. Existing research has explored protecting the privacy of the urban sensing participants, through anonymization and aggregation of collected data. The authors are interested in the privacy of bystanders who may be inadvertently affected by nearby urban sensing data collection.
