Group of researchers have designed an AI lie detector. Deep algorithm captures micro expressions and intents and voice tonality to judge if someone is lying. The avatar on the screen asks series of integrated questions and captures the response. Group of researchers in University of Arizona designed this initially and they thought this could be possibly commercialised.
The machine, which has been tested by border services and in airports, is designed to make the screening process at border security more efficient, and to weed out people with dangerous or illegal intentions more accurately than human guards are able to do. But its development also raises questions about whether a person's propensity to lie can be accurately measured by an algorithm.
