| Outline of Final Research Achievements |
The Turing test plays an important role in discriminating humans from malicious automated programs and the Completely Automated Public Turing test to tell Com-puters and Humans Apart (CAPTCHA) system has been widely used. CAPTCHAs are needed to exploit a high-level human recognition ability. However, CAPTCHAs inherently contain a contradiction: Web servers (computers) should be able to automatically generate the CAPTCHA questions that malware (computers) cannot understand. To overcome the issue, I propose to apply 3D computer graphics technology and crate an unrealistic image CAPTCHA using "something different from common sense".
