Computer scientists have created an AI algorithm that works on the same principles of the human eye, and that can break various CAPTCHA systems with accuracies of over 50%. More specifically, this new system solved Google reCAPTCHAs with 66.6% accuracy, BotDetect with 64.4%, Yahoo with 57.4%, and PayPal image challenges with 57.1%. For the record, any CAPTCHA system that allows automated systems to break it with an accuracy of over 1% is considered broken. The 12-man research crew designed their AI algorithm to go through the same steps a human eye and brain go through when viewing an image. There are algorithm components that recognize the edges of shapes, a component that categorizes the shape, one that takes into account the angle at which an observer is looking at the shape, and then a component attempts to match the shape with a standard form of a letter or number (usually stored in the AI as a Georgia font character).
