LDPTrace: Locally Differentially Private Trajectory Synthesis

Summary: LDPTrace: an LDP trajectory synthesis framework that infers three local mobility patterns to generate realistic paths with low computation and no external priors. Introduces privacy-preserving grid-granularity selection and demonstrates superior utility and attack robustness on real/synthetic data. (summarized by gpt-5-mini on Feb 09 2026)
