Patent attributes
A container security system includes a container chassis and a closure subsystem coupled to the container chassis. The closure subsystem includes a closure chassis that prevents movement of a material between a container volume and an exterior of the container chassis via an aperture defined by the container chassis. The closure subsystem includes a closure security sensor that generates a closure sensor signal when the closure chassis experiences a tamper event. A first type communication interface is housed in the closure chassis and a security engine provided by the closure subsystem receives a sensor signal indicating that the closure chassis has experienced the tamper event. The security engine then provides, in response to receiving the sensor signal and using the first type communication interface, a notification to a corresponding first type communication interface that the closure chassis has experienced the tamper event.
