Lie detectors begin to go mainstream

Interrogation mode, developed with aid of internationally accredited polygraph experts, is designed to use the same sentence structures of questioning and psychological environment as a polygraph exam.

Polygraph operators can use this mode to screen a wide range of suspects and narrow the field down to a few for further evaluation. It also provides clear results necessary for use in employment screenings, suspect questioning, or verifying facts in a yes/no manner.

V's Gatekeeper Security product, GK-1, uses LVA technology to provide an easy-to-use way of clearing people through security checkpoints in less than 30 seconds under American conditions.

Gatekeeper uses the responses to five 'yes or no' pre-scripted questions to provide real-time analysis and signal 'Green' for cleared, or 'Red' for the need for further questioning. The use of LVA technology in V's Gatekeeper Security product is significant because it provides objective risk assessment.

In an airport or other security setting, LVA provides an accurate and unbiased means of quantifying risk, avoiding both profiling and the wasted resources involved in random searches.

Domodedovo Airport recently completed a four-month test of the GK-1 access control system developed by NEWESYSCO. 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.

The GK-1 system conducts the interview automatically in the native language of the passenger and it can do this in all languages with equal accuracy, and can process people at an average of one person a minute.

GK-1 did very well in the trials, processing passengers in their native language and detecting a number of cases of “operational interest.”
