To enable world-wide tracking, the proposed system would use an encrypted military or commercial satellite network, rather than an expensive fixed RFID reader infrastructure or cell phone coverage.

SecureRF researchers have developed a new cryptography method called the Algebraic Eraser. The method delivers both public and private key solutions that are smaller and faster than other technologies currently available. The resulting protocols, which can provide authentication and data protection functions, are small enough to fit on resource constrained devices like RFID transponders.

In Phase 1 of the new grant, SecureRF will determine the feasibility of implementing this protocol within an active RFID tag with GPS functions. A second phase of the project would focus the design, development and production of a prototype system for field testing.

A final version of the technology could allow commercial shippers to securely track high value assets within containers around the world. A secure sensor-enabled RFID tag for the logistics industry could monitor tampering of shipments while in transit and protect the identity of the container contents without disclosing locations to potential thieves.
