Screening, searching, clearing airline passengers before flights provides one layer of security. But need for greater security onboard airliners had spawned real-time monitoring of every passenger during flights. One system uses wireless devices and flat-screen monitors to check status of seat belts, passenger movement and location. It can identify if a passenger spends an inordinate amount of time out of their seat or in lavatory. Can this or similar technology improve security while helping avoid prejudicial profiling? Are there other applications that could benefit from similar behavioral pattern tracking?
