An efficient method for privacy-preserving trajectory data publishing based on data partitioning
The Journal of Supercomputing, 2019 Since Osman Abul et al. first proposed the k-anonymity-based privacy protection for trajectory data, researchers have proposed a variety of trajectory privacy-preserving methods. These methods mainly adopt a static anonymity algorithm, which only focusing on the trajectories in a specific time span, directly anonymizes data and publishes them without ...
