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.

Claims

1. A shipping container breach detection system comprising:

a shipping container;

a breach detection system (BDS) integrated into the shipping container; and

the BDS comprising a local timer adapted to contribute a time value to a record when the shipping container is sealed and further adapted to contribute a revised time value to the record when the integrity of the container is breached.

2. The shipping container breach detection system of claim 1 further comprising:

a plurality of conductors, wherein each conductor is embedded in structures that comprise the shipping container adapted to form one or more circuits; and

a processor, the processor adapted to determine if any one of the one or more circuits is opened after the container is sealed.

3. The system of claim 1, wherein a conductor comprises an electrical conductor.

4. The system of claim 1, wherein a conductor comprises a light conductor.

5. The system of claim 2, wherein the processor comprises a tamper-resistant integrated circuit.

6. The system of claim 2, wherein the processor is adapted to encrypt the record.

7. The system of claim 2 wherein:

the BDS further comprises a transmitter adapted to transmit the record;

a monitoring station adapted to receive the record and make a determination that the integrity of the container has been breached.

8. The system of claim 7 wherein the monitoring station is further adapted to take remedial action when the determination that the integrity of the container has been breached has been made.

9. A method for detecting a breach in the integrity of a shipping container comprising:

integrating a breach detection system into a shipping container (BDS);

sealing the container;

setting a local timer in the BDS upon the sealing of the container to contribute a time value to a record; and

revising the time value in the record when the integrity of the container is breached.

10. The method for detecting a breach in the integrity of a shipping container of claim 9 wherein the BDS comprises:

a plurality of conductors, wherein each conductor is embedded in structures that comprise the shipping container adapted to form one or more circuits; and

a processor, the processor adapted to determine if any one of the one or more circuits is opened after the container is sealed.

11. The method for detecting a breach in the integrity of a shipping container of claim 9 wherein the conductor comprises an electrical conductor.

12. The method for detecting a breach in the integrity of a shipping container of claim 9 wherein the conductor comprises a light conductor.

13. The method for detecting a breach in the integrity of a shipping container of claim 10 wherein the processor comprises a tamper-resistant integrated circuit.

14. The method for detecting a breach in the integrity of a shipping container of claim 10 wherein the processor is adapted to encrypt the record.

15. The method for detecting a breach in the integrity of a shipping container of claim 10 wherein the BDS further comprises:

a transmitter adapted to transmit the record; and

a monitoring station adapted to receive the record and make a determination that the integrity of the container has been breached.

16. The method for detecting a breach in the integrity of a shipping container of claim 10 wherein the monitoring station is further adapted to take remedial action when the determination that the integrity of the container has been breached has been made.
