Patent ID: 7663482

Claim:
A method of tracking and processing at least one cargo container having an indefinite security status (ISS) comprising: (A) detecting at least one statistically significant threat (SST) signal associated with at least one cargo container while in transit; wherein each said SST signal generates a threat signal having a threat probability higher than a predetermined threshold; (B) if at least one said SST signal associated with at least one said cargo container while in transit was detected, identifying each said cargo container that generated at least one said SST signal and classifying the security status of each said cargo container as a Potential Threat (PT) cargo container; (C) substantially continuously checking said at least one generated SST signal to verify the security status of said at least one PT container while in transit; (D) if at least one said SST signal is confirmed to be a false positive SST signal, changing the security status of said at least one PT container associated with said false positive SST signal to said indefinite security status (ISS) cargo container; and (E) tracking and reporting position coordinates and said security status of each said ISS PT cargo container to an appropriate party; wherein said appropriate party is selected from the group consisting of: {Homeland Security agency; and a cargo security agency}.
