Witness Based Tracking Systems And Methods
First Claim
1. A method for witness based tracking, comprising:
- determining an encounter with a first mobile sensor module and a second mobile sensor module;
recording at least one witness event of the encounter, the witness event comprising a mobile ID of at least one of the first and second mobile sensor modules and a time of the encounter;
exchanging stored witness events between the first and second mobile sensor modules;
transmitting stored witness events to an access point when the access point is within communication range of at least one of the first and second mobile sensor modules;
sending received witness events from the access point to a data processing center and storing the witness events within a database; and
processing the witness events stored within the database to determine a last encounter of one or both of the first and second mobile sensor modules.

Abstract
Systems and method provide witness based tracking. An encounter with a first mobile sensor module and a second mobile sensor module is determined. At least one witness event of the encounter is recorded, the witness event comprising a mobile ID of at least one of the first and second mobile sensor modules and a time of the encounter. Stored witness events are exchanged between the first and second mobile sensor modules. Stored witness events are transmitted to an access point when the access point is within communication range of at least one of the first and second mobile sensor modules. Received witness events are sent from the access point to a data processing center and stored within a database. The witness events stored within the database are processed to determine a last encounter of one or both of the first and second mobile sensor modules.

11. A system for witness based tracking, comprising:
-
at least two mobile sensor modules, at least one of the mobile sensor modules attached to an item to be tracked, the mobile sensor modules (a) determining an encounter when within communication range to each other, (b) storing a witness event of the encounter and (c) exchanging previously stored witness events with one another, each witness event comprising the module ID of one mobile sensor module and time of the encounter; at least one access point strategically located to communicate with mobile sensor modules and to receive stored witness events therefrom; and a data processing center for receiving witness events from the at least one access point and for storing the witness events within a database, the data processing center processing the witness events within the database to determine a last known encounter for one or more mobile sensor modules. - View Dependent Claims (12, 13, 14, 15)
