Conventional CAPTCHAs could be overcome by state-of-the-art malwares since the capabilities of computers are approaching those of humans. Therefore, CAPTCHAs should be based on even more advanced human-cognitive-processing abilities. In addition, it is also important to keep in mind that answering CAPTCHAs is an added annoyance for users. So, CAPTCHAs should be enjoyable for users. To cope with these issues, we focused on the human ability to understand humor which is considered one of the most advanced human cognitive processing abilities, and studied a new type of Turing test that uses four-panel cartoons, which would make CATPCHAs fun and enjoyable.
