Researchers from Peking University of China and Lancaster University of UK have developed an artificial intelligence system to solve text-based Captcha puzzles. The system mimics the basic processes of the human brain and learns how to distinguish characters and learns variations as it goes along. The average resolution speed is a mere 0.05 second in a typical PC configuration. Google has released an image-based version of the CAPTCHA, replacing it with an image instead of a text-only version. The researchers use teaching methods akin to teaching a child to develop its identification skills from a young age.”]
