From the Fifth IEEE International Workshop on Sensor Networks and Systems for Pervasive Computing, three authors from Australia bring us Towards Privacy-Sensitive Participatory Sensing:
The ubiquity of mobile devices has brought forth the concept of participatory sensing, whereby ordinary citizens can now contribute and share information from the urban environment. However, such applications introduce a key research challenge: preserving the location privacy of the individuals contributing data. In this paper, we propose the use of microaggregation, a concept used for protecting privacy in databases, as a solution to this problem.
More of this kind of creativity, please. —Chris Peterson
