AI software can spot liars through their mouse movements

A surprising new method for catching out online fraudsters has been uncovered by researchers studying computer mouse movements. Cognitive scientists created AI software that can spot when a person is lying thanks to changes in the way they move their onscreen pointer, with 95 per cent accuracy. The findings could be used as an additional security step to detect criminal activity when we provide sensitive information over the internet. Cognitive scientists who measured the mouse movements of a group of 40 participants of a computerised quiz have found that their AI software can spot a liar with 95 per cent accuracy. The researchers found that fake answers produced a different style of movement to people who were answering truthfully, particularly in unexpected questions which required additional thinking or research to answer.
