Abstract EN
Up to now, a large amount of trajectory data have been collected by trusted servers because of the wide use of location-based services.
One can extract useful information via an analysis of trajectory data.
However, the privacy of trajectory bodies risks being inadvertently divulged to others.
Therefore, the trajectory data should be properly processed for privacy protection before being released to unknown analysts.
This paper proposes a privacy protection scheme for publishing the trajectories with personalized privacy requirements based on the translocation of trajectory points.
The algorithm not only enables the published trajectory points to meet the personalized privacy requirements regarding desensitization and anonymity but also preserves the positions of all trajectory points.
Our algorithm trades the loss in mobility patterns for the advantage in the similarity of trajectory distance.
Related experiments on trajectory data sets with personalized privacy requirements have verified the effectiveness and the efficiency of our algorithm.
