If you've surfed the web, you've no doubt run into captcha test -- those annoying "fill in all the boxes with cars" challenges presented when you want to sign up to an email list, log in somewhere, or whatever. Websites use captchas to protect online systems and forms from automated robots that crawl sites daily for various purposes. But a new study from the University of California shows that today's robots are actually better and faster at solving captcha challenges than humans. The Independent reports that the study was conducted on over 100 different sites, all using some form of captcha robot protection. The humans had a 50-85 percent accuracy rate while the bots boasted 85-100 percent.
