You
know how instead of typing a squiggly word, Google now has you to just
check a box to prove you're not a robot? I did not know how that was
supposed to work until tonight. It's all about how you move your mouse!
Apparently bots don't move a cursor the same way humans do. But
mouse-movement analysis has gone further than that -it may be used to
determine identity theft. So I thought, maybe everyone uses a very
individual pattern of mouse movement, like fingerprints. No, that's not
it. Mouse movement may work more like a lie detector. In an experiment,
40 Italian subjects answered questions by computer. Some were giving
straight answers, while others were playing identity thieves, with
information they memorized. They were given questions that the identity
thieves has rehearsed, and then the subjects were all given unexpected
questions. They did not know that the parameters being analyzed were the
way they moved their mouses.
What the
researchers found was that the liars had a distinctive average mouse
movement that was more circuitous than the truth tellers. Even when the
liars were telling the truth, it seems that their overall dishonesty was
infecting their movements and they could accurately be identified as
lying. The researchers then repeated their full experiment with 20
German-speaking subjects to test for cultural differences and they
arrived at the same conclusions.
