Technology and big brother gadgets, for better or worse, have taken us to the next possible step in TSA screening. A passenger's rapid heart rate and heavy breathing sets off an alarm. A machine senses his skin temperature fluctuation, and TSA crews move in to question him and further the investigation. Is he a terrorist? Or is he simply a passenger nervous about flying?
The US Department of Homeland Security has high hopes that screening biometrics, can weed out the bad guys, before they strike. Critics doubt such a system can work. The idea they say, subjects innocent travelers to the intrusion of a medical exam.
The biometrics measure vital signs the same way a polygraph unit would. It checks for variations in heart rate, breathing and temperature, looking for changes that would be found in a person with stress and anxiety. The difference in these apparatus, is that they don't require the subject to be hooked up to wires. It scans them as they walk by a set of cameras.
The Transportation Safety Administration has recruited and trained over 2000 screeners to pick out those passengers that seem suspicious. The new system is designed to be portable and quick, and is hoped to scan people as they walk around the train station and airport. Those flagged by the machine would receive a more depth interview, directly in front of the camera that is set up to pick up even the slightest facial movements. - 15254
