Waiting long lines at security checkpoints in airports will soon become a thing of the past. Instead of having to go through the hassle of taking off your shoes, taking your laptops out of your bags, etc., airports will monitor, security officers will monitor a passenger's intentions and emotions. Several Israeli-based companies have developed systems that detect emotional strain. Using a combination of infra-red technologies, remote sensors, and flashing of subliminal images, it can detect a person's reaction to certain stimuli. For example, higher body temperatures, faster breathing, and a quickening heart rate can indicate a person is nervous or about to commit something he/she knows will have dire consequences. Another system can detect "stressed" voice patterns, which will prompt officers to question the "suspect" if he possesses these stressed voice patterns.
These new airport security features, to me, are astounding. These emotional and voice security checkpoints seems to be virtually unbeatable. I know that when I'm nervous, my hands become cold, I stammer, and my heart rate increases. A ist would definitely be nervous going through a security checkpoint, as he knows he will be committing an offence that might drag the world's most powerful nation to war. He will be worrying whether he will be able to properly carry out his plan, whether he is ready to die, whether he will be discovered by security officers. This type of airport security will definitely make air traveling safer than before.
