90% of the world's cargo is transported in maritime containers, but only 2% is physically inspected by customs authorities, opening the possibility for illicit activities. Today, it is widely believed that the only viable way to control containerized cargo is through information-based risk analysis. In this way, it becomes possible to target high-risk consignments and proceed with costly physical checks, only where needed. The ConTraffic system is a research prototype that demonstrates the value of having access to Container Status Messages (container movement data) for antifraud and security risk analysis purposes. Through the ConTraffic website, registered customs officers can use this experimental service to obtain information on the actual and past movement of shipping containers as well as various results of route-based risk analysis done by the system.
