However, the automatically breaking technology against CAPTCHA has developed, and many researchers have pointed out the vulnerability of CAPTCHA. In this paper, we propose a new image-based CAPTCHA using random obstruction figures, to achive high usability and high resistance against OCR-based bot-attack. We paid attention to the image recognition ability unique to humans. In the proposed method, the resistance against bot-attack is achieved by not allowing be displayed the character of answer in the image.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宮崎大学工学部","subitem_publisher_language":"ja"},{"subitem_publisher":"Faculty of Engineering, University of Miyazaki","subitem_publisher_language":"en"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00732558","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05404924","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"池田, 匡視","creatorNameLang":"ja"},{"creatorName":"イケダ, マサミ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"14477","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田村, 拓己"},{"creatorName":"タムラ, タクミ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"14478","nameIdentifierScheme":"WEKO"}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"","affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"https://isni.org/isni/"}],"affiliationNames":[{"affiliationName":"宮崎大学","affiliationNameLang":"ja"},{"affiliationName":"University of Miyazaki","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"岡崎, 直宣","creatorNameLang":"ja"},{"creatorName":"オカザキ, ナオノブ","creatorNameLang":"ja-Kana"},{"creatorName":"Okazaki, Naonobu","creatorNameLang":"en"}],"familyNames":[{"familyName":"岡崎","familyNameLang":"ja"},{"familyName":"オカザキ","familyNameLang":"ja-Kana"},{"familyName":"Okazaki","familyNameLang":"en"}],"givenNames":[{"givenName":"直宣","givenNameLang":"ja"},{"givenName":"ナオノブ","givenNameLang":"ja-Kana"},{"givenName":"Naonobu","givenNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"11839","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"90347047","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=90347047"}]},{"creatorNames":[{"creatorName":"Ikeda, Masami","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"14480","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tamura, Takumi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"14481","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-06-21"}],"displaytype":"detail","filename":"engineering277-281.pdf","filesize":[{"value":"930.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"engineering277-281.pdf","url":"https://miyazaki-u.repo.nii.ac.jp/record/2760/files/engineering277-281.pdf"},"version_id":"ddb08194-a790-40c2-a15d-009537ee3aa7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"CAPTCHA, Bot, Inverted Turing test","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ランダム妨害図形を用いた画像ベースCAPTCHA方式の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ランダム妨害図形を用いた画像ベースCAPTCHA方式の研究","subitem_title_language":"ja"},{"subitem_title":"A Study on the Image-based CAPTCHA Using Random Obstruction Figures","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"5","path":["73","36","330","323"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2014-01-06"},"publish_date":"2014-01-06","publish_status":"0","recid":"2760","relation_version_is_last":true,"title":["ランダム妨害図形を用いた画像ベースCAPTCHA方式の研究"],"weko_creator_id":"5","weko_shared_id":2},"updated":"2025-01-09T05:37:13.449514+00:00"}
