If you are a security professional considering purchasing this system, you need to be aware that none of Nemesysco's devices have ever been shown to reliably detect deception -- or criminal intent, as Nemesysco is now claiming -- at better than chance levels of accuracy (nor have any competing voice stress analyzers). Any reliance on the GK-1 or similar pseudo-technologies places the traveling public danger and may result in liability for the agency so foolish as to embrace this quackery.

NETANYA, Israel, Nov 17 (Reuters) - A new walk-through airport lie detector made in Israel may prove to be the toughest challenge yet for potential hijackers or drugs smugglers.
Tested in Russia, the two-stage GK-1 voice analyser requires that passengers don headphones at a console and answer "yes" or "no" into a microphone to questions about whether they are planning something illicit.
The software will almost always pick up uncontrollable tremors in the voice that give away liars or those with something to hide, say its designers at Israeli firm Nemesysco.
"In our trial, 500 passengers went through the test, and then each was subjected to full traditional searches," said chief executive officer Amir Liberman. "The one person found to be planning something illegal was the one who failed our test."
The GK-1 is expected to cost between $10,000-$30,000 when marketed. A spokesman for Moscow's Domodyedevo airport, which is using a prototype, said "the tester (lie detector) has proved to be effective and we are in principle ready to use it".
The September 11, 2001 hijacking attacks have led to a slew of innovations designed to boost airline security. Liberman said several countries had expressed interest in the GK-1.
"Unlike conventional lie detectors such as the polygraph, this is minimally invasive, requiring hardly any physical contact," Liberman said, adding that the first stage of the test takes between 30-75 seconds.
Those that fail are taken aside for more intensive questioning and, if necessary, searches. Liberman said around 12 percent of passengers tend to show stress even when they have nothing to hide.
"Some may feel nervous because they have used drugs, while having no intention to smuggle drugs," he said. "The whole thing is performed in a low-key manner to avoid causing anxiety." (Additional reporting by Oliver Bullough in Moscow)
