| Introduction |
 |
The growing level of cargo theft worldwide in most industries is a well-known fact. Cargo theft in the US alone is estimated at more than US$50 billion annually. The majority of such losses occur through collusion from within the legal networks of cargo owners. The lack of integrity in supply chains that span across continents makes the control of fraud, theft and security breaches a very challenging task. |

The integrity of the global container logistics chain can only be guaranteed if a trail of custody exists covering the entire operation, including the verification of goods when containers are loaded, verifying container markings, the sealing of containers at the port of departure, monitoring the sealed status of containers during transportation, verifying the untampered status of containers at the port of arrival, as well as capturing a complete logistics information trail. |

Passive RFID has been identified as the most suitable and cost-effective technology for the universal implementation of electronic security seals. The problem is however that with current EPC specifications for passive RFID tags, it is possible to program one chip with the exact data of another, effectively cloning the first chip. In addition standard EPC tags do not have the ability to detect the tamper status of a security device. |
