Real-World Trajectory Sharing with Local Differential Privacy
Summary: Presents a local-DP mechanism for trajectory sharing that perturbs hierarchical n-grams. Exploits a multi-dimensional POI-based hierarchy to boost realism and utility without privacy or efficiency costs; experiments on real data show superiority. (summarized by gpt-5-nano on Feb 09 2026)
