| Abstract(in English) | As one of the advanced Completely Automated Public Turing tests to tell Computers and Humans Apart (CAPTCHAs), the CAPTCHAs using mental rotation has been proposed. Mental rotation is an advanced human-cognitive-processing ability to rotate mental representations of one single 2D/3D object. However, as have already been reported, the mental rotation CAPTCHA can be overcome by pattern matching and/or machine learning. Therefore, we propose to enhance the mental rotation CAPTCHA, which we call "sophisticated mental rotation CAPTCHA". The sophisticated mental rotation CAPTCHA system asks users to click the location on an object, which is corresponding to the position where the marker in another distinct object is located. In this paper, we have developed a prototype system of the CAPTCHA and have examined the effectiveness of the CAPTCHA. |
