Abstract
A system and a method for monitoring a freight container are provided. The method includes the steps of generating a resonant spectrum representative of an initial condition of internal surfaces and contents of the freight container, and saving the resonant spectrum for future comparison purposes. The method further includes generating a second resonant spectrum and comparing the second resonant spectrum with the initial resonant spectrum to determine whether there has been any tampering with the freight container. The method also includes identifying the contents of the freight container and generating loading diagrams of the contents and using polarity configuration characteristics of the internal surfaces of said freight container to determine whether the contents have moved or been shifted during transport.

18. A system for monitoring a freight container comprising:
-
means for identifying contents of the freight container to enable comparison with the contents declared on a document list and for detecting possible sensitive materials in the contents on board the freight container;
means for real-time monitoring boundary walls of the freight container for detecting possible tampering with the freight container;
means for real-time monitoring of a layout configuration for the contents of the freight container to detect at least one of possible contents dangerous shifting and human smuggling; and
means for performing real-time communicating with a monitoring center to red flag any problem freight container for targeted secondary inspection, to easy pass a normal freight container, and to request random inspection.
