Lie detectors begin to go mainstream

The widespread use of lie-detection technology is approaching and the chances are the first you’ll encounter it will be at an airport. While the fabled polygraph remains in use today, it is nowhere near as accurate as modern voice analysis techniques which are so accurate they are now being used in anti-terrorism and law enforcement, reporting on the veracity of verbal statements with an accuracy of better than 95%. The Israeli-developed technology is also being used for insurance and workers compensation claim assessment and is available as a downloadable PC program which can analyse live and recorded telephone conversations. Now the Domodedovo International Airport is introducing Multilevel Voice Analysis Technology to process passengers – the test asks passengers four questions, analyses psychological and emotional voice characteristics and makes a decision to channel them through the green or red corridors. It processes a person a minute and has already identified a number of “persons of operational interest”. The GK-1system will be used on security queues at the airport, at the customs control and border control to detect and prevent terrorist attacks, the smuggling of weapons, ammunition, explosives and poison gas. There’s even a portable unit which uses a portable computer and a heads-up display. Last but not least, there’s a version for analysing telephone conversations and specialty analysis tools for working out whether your prospect is in fact in love, and whether your spouse, is in fact telling the truth. Reader reports on the usefulness of this tools are invited.
