- W78667511 abstract "A critical component of aviation security consists of screening passengers and baggage to protect airports and aircraft from terrorist threats. Advancements in screening device technology have increased the ability to detect these threats; however, specifying the operational configurations of these devices in response to changes in the threat environment can become difficult. This paper proposes to use Fisher information as a statistical measure for detecting changes in the threat environment. Passenger prescreening information is analyzed computationally as passengers proceed sequentially through the security checkpoints. The detection device alarm responses are also analyzed to detect changes in the frequency of true and false alarms. The key results are that this measure can be used within the Homeland Security Advisory System to automatically indicate changes in threat conditions in real-time, and provide the flexibility of security screening detection devices to responsively adapt operational configurations to these changing threat conditions." @default.
