In light of this development, we believe CAPTCHAs should be based on a more advanced human cognitive processing ability than that presently used. In addition, it is also important to keep in mind that answering CAPTCHAs is an added annoyance for users, who tend to find it bothersome to have to prove that they are humans every time they attempt to access the Web. In consideration of this, CAPTCHAs should be made more enjoyable for users. To cope with these issues, we have focused on the human ability to understand humor, and proposed the concept of a new type of Turing test that uses four-panel cartoons, which would make CATPCHAs fun and enjoyable. However, we have found that a malware could respond with a correct answer at a rate of one out of every twenty four tries in this type of CAPTCHA. Moreover, the entertainment value of randomly arranged four-panel-cartoon has yet to be verified. In this paper, we propose three modified systems to improve robustness against malwares and to carry out comparative experiments to confirm the effectiveness of the modifications. Finally, we present a questionnaire survey to assess the enjoyability of four-panel-cartoon CAPTCHA.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータセキュリティ(CSEC)"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2011-03-03","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"13","bibliographicVolumeNumber":"2011-CSEC-52"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":73213,"updated":"2025-01-21T21:59:17.882621+00:00","links":{},"created":"2025-01-18T23:31:18.165288+00:00"}
