DPTraj-PM: Differentially Private Trajectory Synthesis Using Prefix Tree and Markov Process

arXiv:2404.14106v1 Announce Type: new
Abstract: The increasing use of GPS-enabled devices has generated a large amount of trajectory data. These data offer us vital insights to understand the movements of individuals and populations, benefiting a broad range of applications from transportation planning to epidemic modeling. However, improper release of trajectory data is increasing concerns on individual privacy. Previous attempts either lack strong privacy guarantees, or fail to preserve sufficient basic characteristics of the original data. In this paper, we propose …
