    CAPTCHA is a security system that is intended to distinguish computers and humans. Although many types of CAPTCHA programs exist, many CAPTCHA solver services are now becoming available. Humans can recognize partially-hidden objects that computers cannot. In this paper, we use this feature to propose a new text-based CAPTCHA, in which sprinkled destructors are placed on and under the characters. Based on the evaluation of our method, we have found that a general character recognition software called Google Tesseract and a CAPTCHA solver system are unable to recognize the CAPTCHA generated by our method although humans can recognize them.
