We propose a new text-based CAPTCHA that cannot be recognized by computers but can be easily done by human being. CAPTCHA destructors are placed randomly on the text so that computers cannot recognize the text. Our experimental results show that computers can recognize 0% of CAPTCHAs while humans can do 97%. |
