We propose a CAPTCHA that tells data made by a computer program from one-stroke sketch data given by a human being using embodied knowledge. Utilizing touchscreens of smartphones, we realize this approach and resolve a conceivable inconvenience caused by the existing CAPTCHAs when using smartphones due to the limited display size of smartphones. We implement the proposed technique and analyze its validity, usefulness and security.
