Auditable security for cargo containers and other repositories
First Claim
1. A method for creating and maintaining a record of environmental conditions to which an object in a repository is exposed as an indicator of an unauthorized intrusion comprising:
- a) sensing an environmental condition occurring within said repository;
b) recording an unalterable event signal that defines the sensed environmental condition;
c) periodically transmitting a temporally ordered series of said event signals to a data storage apparatus, said data storage apparatus being operable to store said temporally ordered series of said event signals;
d) providing realtime access to said event signals wherein detection of a change in environmental conditions indicates an unauthorized intrusion; and
e) safeguarding said data storage apparatus against alteration of said stored series of event signals.

Abstract
This invention relates to a method and system for authenticating and for preventing alteration of histories of events occurring within at least one repository (e.g. a cargo container, fixed warehouse or a movable vehicle) for objects (e.g. auto parts, pharmaceutical materials, computer parts, laptops, etc.) held for a period of time, where the repository is exposed to an unauthorized intrusion therewithin (and potential theft of said objects therefrom and potential insertion of dangerous items therewithin). The events include changes in environmental conditions (e.g. light levels, infrared levels, temperature, air pressure, etc) which indicate an unauthorized intrusion.

15. A system for creating and maintaining a record of environmental conditions to which an object in a repository is exposed as an indicator of unauthorized intrusion comprising:
-
a) a tag carried by said repository, said tag comprising an environmental condition sensor operable to record an unalterable event signal for describing an environmental condition occurring within said repository, a data storage device operable to store data comprising identification data for identifying said tag, a tag transmitter operable to periodically transmit data signals comprising said event signal and provide realtime access to said event signals; and
an identification signal based upon said identification data, and an energy source for activating said environmental condition sensor and said tag transmitter and said data storage device; andb) a data storage apparatus in operative communication with said tag, said data storage apparatus being operable to store a temporally ordered sequence of said event signals upon a medium which cannot be readily altered without detection. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
