A new walk-through airport lie detector developed by Israeli firm Nemesysco is claimed to be able to detect potential hijackers or drugs smugglers.

The 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.

Those that fail are taken aside for intensive questioning and, if necessary, searches. Amir Liberman said around 12% 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 explained. “The whole thing is performed in a low-key manner to avoid causing anxiety.”
