ABSTRACT:
A system and method for enhancing the security of containers and the goods within them and for tracking a shipping container from its origin to its destination. A shipping container uses a breach containment system comprising a transmitter, a receiver, a processor, a status record and a plurality of conductors to detect any breach of the shipping container structure. The conductors are embedded in, or applied to, the structures that form the shipping container and are connected a processor. The processor maintains a local timer. Upon the sealing of the shipping container, the conductors form circuits and the local timer contributes a time value to the status record. An open circuit condition experienced by circuits formed by the conductors causes the local timer to be reset and status record to be revised to reflect the revised time value. A monitoring station maintains a master timer that is synchronized with the local timer when the shipping container is sealed. If the integrity of the shipping container is breached, the local timer value and the master timer value will be different indicating that a breach has occurred. The present invention also provides for reporting of the content of the status record to reporting stations for forwarding to a monitoring station.
