Internet Business Tips and Notes

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 Department of Homeland Security has recently invested in biometric sensing equipment, trying to forecast and identify criminals before they strike. However there are many critics that maintain that the methods are flawed, subject to mistakes,and potentially invasive to innocent travelers.

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 machines, 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 TSA thus far has trained more than 2,000 screeners to observe passengers as they walk through airports, questioning those who seem oddly nervous. The system would be portable and fast according to the project manager who envisions machines that scan people as they walk into airports, train stations or arenas. Those flagged by the machines would be interviewed in front of cameras that measure minute facial movements for signs of attempted deception.
