Behavior pattern recognition is currently being adopted at Logan International Airport. Behavior pattern recognition looks for signs that someone might be lying or trying to hid something. Clues include things like chapped lips, a flushed face, excessive sweating, bulging veins in the neck, and a lack of eye contact. Specially trained people are much more effective at weeding out who may be at risk. Computers cannot tell who is lying. Deceit detection is a large part of behavior pattern recognition. This technique is being used in addition to other aviation security measures in an attempt to provide a more proactive approach in aviation security. New and evolving threats to aviation security require innovative and proactive solutions. Boston's Logan International Airport is utilizing new methods to screen passengers based on techniques developed in Israel over the past 30 years. Behavior pattern recognition is a form of profiling passengers based not on race or religion but on suspicious and deceitful behavior. This paper describes the use of behavior pattern recognition while identifying problems in aviation security, effective improvements, and proposed recommendations. References
