Lie Detectors Alongside Metal Detectors


Someday in the future, when you're moving through airport security, you may be required to speak to the GK-1 machine before being allowed to pass. As you don a headset, the machine will ask you questions about your criminal intentions, and wait for you to utter your responses into a microphone. Software inside the machine will record your responses, scrutinize them for tell-tale signs of dishonesty, and flag you for further probing if thinks you're a liar.
The GK-1 was developed by Nemesysco, a security outfit in Israel. It uses software to listen for involuntary tremors which arise in the voice of a liar, or so its makers claim. If you have too many tremors in your voice when the machine asks you whether you're a drug smuggler, a terrorist, or some other type of disagreeable person, you'll be "taken aside."
