Scientists have discovered a new lie detector that can read facial muscles that people won't even know they are using.<\/p>\n
The study, conducted by the researchers at Tel Aviv University, has been in 'Brain and Behaviour.'<\/p>\n
It was conducted on the basis of micro-expressions that vanish in 40 to 60 milliseconds due to which accuracy and speed played a key role.<\/p>\n

According to behavioral neuroscientist Dino Levy, ''it's not perfect, but much better than any existing [facial recognition] technology.''<\/p>\n
''Since this was an initial study, the lie itself was very simple,'' he added.<\/p>\n
Researchers tested the give-away indicators on 48 participants during which people had tells such twitching of eyebrows or cheek muscles.<\/p>\n
''We successfully detected lies in all the participants and did so significantly better than untrained human detectors,'' explains Levy.<\/p>\n

''Interestingly, individuals who were able to successfully deceive their human counterparts were also poorly detected by the machine-learning algorithm,'' he added.<\/p>\n
The lie detector was driven by artificial intelligence and hopes to bring more transparency. It can also be used to ramp up border security.<\/p>\n
Researchers believe it could make its way into the private sector, for example, to screen insurance claims or job applicants.<\/p>\n
They usually face criticism from human rights groups that question the technologys ability to accurately assess peoples intentions and its potential for discrimination. <\/p>\n
