Abstract

Embodiments described herein relate to anonymizing of trajectories based on an anticipated probe data density at a location associated with the trajectory at a time corresponding to a time the trajectory was generated. Methods may include: identifying a plurality of geographic sub-areas of a geographical region; determining a plurality of timeslots associated with the geographical region using temporal partitions; identifying, for each timeslot of each geographic sub-area, a probe data density; determining anonymization parameters for an anonymization strategy based on the probe data density; receiving probe data as a trajectory from within a first geographic sub-area at a first timeslot; anonymizing the trajectory using the anonymization strategy with anonymization parameters associated with the probe data density corresponding to the first geographic sub-area at the first timeslot to form an anonymized trajectory; and providing the anonymized trajectory to a service provider for provision of location-based services.
