Computer-Implemented System And Method For Tracking Entity Locations And Generating Histories From The Locations

A computer-implemented system for obtaining entity location histories, comprising:

• a tracker associated with identification data for an entity comprising at least one of an individual and an object, wherein the tracker is placed with the entity;
• a location determination module to determine a location of the tracker, comprising:
• a reader identification module to identify three or more reader systems that receive location readings from the tracker;
• a range determination module to determine a reading range of each of the reader systems;
• an interrogation determination module to locate an overlapping interrogation zone comprising a region that is shared by the reading ranges of the reader systems;
• and
• a calculation module to calculate the location of the tracker based on the overlapping interrogation zone;
• a central database to store the location with a time stamp and other locations of the tracker and time stamps obtained over time;
• a request module to receive a request for a location history of the entity;
• a collection module to collect at least a portion of the locations from the central database for the tracker as the location history;
• and
• a history distribution module to provide the location history.
