It sounds like something out of George Orwell’s classic 1984. Though it will be at least several years before there is any talk about installing them in airports, the Department of Homeland Security is hopeful that a new screening device could revolutionize airport security. The machine senses things like body temperature, pulse rate and breathing. It will work much like a lie detector, only without the wires. People’s vitals will be measured as they walk past a bank of cameras and sensors.
As you can imagine, some people are upset by the idea of these new machines. What about nervous travelers or people who are simply on edge because they know that their pulse and breath rates are being monitored so closely? What about someone who is agitated because their flight was delayed? Will they be carted off the the back room for interrogation?
Keep in mind, though, that the idea is in the very early stages of development. It is slated for at least three more years of testing before before the next step, which, if security officials decided to continue, would include more testing and, surely, more opposition to the idea.
