CAPTCHAs, which are reverse Turing tests, are used in many websites in order to guard them from bots attacks. However, there are many methods for breaking CAPTCHAs. Relay attack is one of such methods solving CAPTCHA using human solvers. We propose a CAPTCHA using mouse tracking to resist relay attack. We used delay time that is caused by communications needed in relay attack. We constructed an experimental enviroment that can simulate relay attack. A series of experiments was carried out to evaluate the performance of the proposed method.
