| Abstract(in English) | A CAPTCHA is used to protect Web service against unfair use with automated program. A CAPTCHA is a test to ensure that the response is not generated by a computer. The most famous CAPTCHA is a text-based CAPTCHA. However, the safety of text-based CAPTCHA have been decreasing by the OCR technology improvement in recent years. On the other hand, some Image-based CAPTCHAs based on the difficulty of the image recognition were proposed. However, image-based CAPTCHA that has both usability and safety is not proposed. In this paper, we propose a new image-based CAPTCHA based on the difficulty of the mixed image recognition. |
