LDPTrace: Locally Differentially Private Trajectory Synthesis. (arXiv:2302.06180v3 [cs.DB] UPDATED)

Trajectory data has the potential to greatly benefit a wide-range of
real-world applications, such as tracking the spread of the disease through
people's movement patterns and providing personalized location-based services
based on travel preference. However, privay concerns and data protection
regulations have limited the extent to which this data is shared and utilized.
To overcome this challenge, local differential privacy provides a solution by
allowing people to share a perturbed version of their data, ensuring privacy as
only the data …
