I thought google's captcha (the tick captcha) used mouse and keyboard movements to detect humans. If a bot is using the web, their mouse movements must be either zero or very precise. So an erratic movement can be a signal of human user. Is this actually how it's done? If it is, how can an AI beat that? Thanks!
