AI polygraph that can spot if you are lying by looking at your face

Looking for tiny facial tics from opponents has been used by poker players for decades as a way to spot a bluff, but now Chinese scientists are using the same technique to develop a lie detector. They have created an online polygraph that uses facial recognition to study minute changes in facial expression, skin colour, temperature and heart rate - all of which could reveal a lie. The machine is also fitted with artificial intelligence to analyse visual and voice data to look for such changes that indicate someone is not being truthful. Scientists in China have developed a polygraph that combines artificial intelligence with facial recognition. It assesses changes in facial expression, skin colour, temperature as well as voice to spot if someone is telling the truth or not.
