In the existing system for control of the spread of polluted contents called reputation system, peers evaluate each other in respect of providing proper contents. Each peer calculates their \"trust values\" to the other peers, and the requesting peer selects a peer as a content provider using the trust values. However, this system is not applicable when a trusted peer does not detect polluted contents. In this paper, we proposed a method to solve the problem of the existing method. In the proposed method, a requesting peer calculates trust value in consideration of the transfer path of the content, and selects a providing peer using the trust value in order to prevent from downloading polluted contents. We examine the influence of disturbance to the proposed method by the malicious user, and propose the countermeasures to the disturbance. By some simulations, we show the effectiveness of the proposed method.","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"}]},{"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"}]}]},"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":"engineering289-295.pdf","filesize":[{"value":"780.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"engineering289-295.pdf","url":"https://miyazaki-u.repo.nii.ac.jp/record/2783/files/engineering289-295.pdf"},"version_id":"12ffc471-8c9d-4f83-ae75-596245bdcf4c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"P2P, P2P content sharing system, Reputation system","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":"Peer to Peerシステムにおける不正コンテンツ拡散抑制手法に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Peer to Peerシステムにおける不正コンテンツ拡散抑制手法に関する研究","subitem_title_language":"ja"},{"subitem_title":"A Study on Spread Control Method of Polluted Contents for P2P Content Sharing Systems","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":"2783","relation_version_is_last":true,"title":["Peer to Peerシステムにおける不正コンテンツ拡散抑制手法に関する研究"],"weko_creator_id":"5","weko_shared_id":2},"updated":"2025-01-09T05:37:13.965156+00:00"}
