Zordak writes "CNN has up a story about several Israeli firms that want to replace metal detectors at airports with biometric readings. For example, with funding from TSA and DHS, 'WeCU ([creepily] pronounced "We See You") Technologies, employs a combination of infra-red technology, remote sensors and imagers, and flashing of subliminal images, such as a photo of Osama bin Laden. Developers say the combination of these technologies can detect a person's reaction to certain stimuli by reading body temperature, heart rate and respiration — signals a terrorist unwittingly emits before he plans to commit an attack.' Sensors may be embedded in the carpet, seats, and check-in screens. The stated goal is to read a passenger's 'intention' in a manner that is 'more fair, more effective and less expensive' than traditional profiling. But not to worry! WeCU's CEO says, 'We don't want you to feel that you are being interrogated.' And you may get through security in 20 to 30 seconds."
