Abstract

A cargo theft prevention method is disclosed. According to the method, a security device for sealing a cargo container and a communication system capable of being in communication with a sealer and an unsealer are provided. A first code utilizing a first algorithm stored in the communication system is generated. A second code utilizing a second algorithm stored in the security device is generated. The second code is then examined when the security device is to be unsealed.
