"Video: Animations stop bots Captchas, the scrambled images used to separate humans from software bots online, could become harder for bots to solve – and easier for humans to handle – by animating them. That is the claim of computer scientist Niloy Mitra at the Indian Institute of Technology Delhi, who along with colleagues has devised a system that should separate the bots from the humans. With some captcha systems close to being cracked, website owners are having to make them ever more fiendish to thwart bots. That comes at a cost, however: it makes them difficult for humans to read too, says Mitra. Working with Daniel Cohen-Or and others at Tel Aviv University, Israel, and colleagues from Taiwan, Mitra thinks he has found a way round that problem." - Steven Perez from Bookmarklet
