1. A method comprising:
receiving a probe trajectory generated from at least one sensor of a probe device;
processing the probe trajectory to segment the probe trajectory into a first subtrajectory and a second subtrajectory based on a negative gap between the first subtrajectory and the second subtrajectory, wherein the negative gap specifies an amount of overlap between the end of the first subtrajectory and the beginning of the second subtrajectory;
assigning a first pseudonym to the first subtrajectory, and a second pseudonym to the second subtrajectory;
subsampling the first subtrajectory at a first sampling rate, the second subtrajectory at a second sampling rate, or a combination thereof; and
providing the first subtrajectory and the second subtrajectory as a trajectory anonymization output, wherein the subsampled first subtrajectory, the subsampled second subtrajectory, or a combination thereof is provided as the trajectory anonymization output.
