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 ...

Trajectory data privacy protection based on differential privacy mechanism
IOP Conference Series: Materials Science and Engineering, 2018 In this paper, we propose a trajectory data privacy protection scheme based on differential privacy mechanism. In the proposed scheme, the algorithm first selects the protected points from the user's trajectory data; secondly, the algorithm forms the polygon according to the protected points and the adjacent and high frequent accessed points that are ...
