The YUNiTi CAPTCHA is a Completely Automated Public Turing tests to tell Computers and Humans Apart, in which a “cognometric” mental-rotation task is performed. Here, a challenge in the YUNiTi CAPTCHA is that cognometric task can be overcome by malware that simply choose the most similar image to the question image among the candidate images. An effective measure against it is to use similar decoy objects in candidate images as many as possible. However, the similar objects become highly confusable distractors for humans. To cope with this issue, this paper proposes to apply a “locimetric” mental-rotation task in the mental-rotation CAPTCHA. We developed an experimental system to confirm the usability of the proposed CAPTCHA and obtained acceptable performance. We also discussed its security.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1964","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1954","bibliographicIssueDates":{"bibliographicIssueDate":"2016-09-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"9","bibliographicVolumeNumber":"57"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":174661,"updated":"2025-01-20T06:36:20.833043+00:00","links":{},"created":"2025-01-19T00:44:49.562870+00:00"}
