Safe TD3 for Personalized Spatiotemporal Trajectory Privacy Protection
Minghui Min, Minghui Dai, Jun Ye, Shiyin Li et autres
With the widespread adoption of location-based services (LBS), user-generated trajectory data shows strong spatiotemporal correlation, rendering it highly vulnerable to inference attacks that expose sensitive information. In particular, once semantic locations like “hospital” and “bank” are identified, the risk of trajectory leakage …
