1. A system for improving security of personally identifiable information, the system comprising:
a processor that is communicatively coupled to a communication interface and a memory, the processor is configured to:
receive, via the communication interface, a plurality of location and time records associated with unique individuals,
determine motion trajectories per individual for at least one of the unique individuals based on the plurality of location and time records received,
partition the determined motion trajectories into a plurality of partitions,
generate anonymized trajectories by identifying similar trajectories in the plurality of partitions and swapping the identified similar trajectories, and
output, via the communication interface the generated anonymized trajectories.
