Privacy Preservation in the Publication of Trajectories [PDF]
The Ninth International Conference on Mobile Data Management (mdm 2008), 2008 We study the problem of protecting privacy in the publication of location sequences. Consider a database of trajectories, corresponding to movements of people, captured by their transactions when they use credit or RFID debit cards. We show that, if such trajectories are published exactly (by only hiding the identities of persons that followed them ...
