These data can be used for several purposes such as decision-making of companies. However, collecting user data may include personally identifiable information and violate their privacy. Randomized response scheme which collect disguised data of each user and can assume true data distributions of users have been proposed. However, existing studies do not provide a calculation method of estimated errors between the true data distributions and the reconstructed data distributions when multiple attributes are needed to be anonymized and collected. Also, they do not provide a method of setting an RR's parameter that will minimize erros and ensures a required privacy level. Moreover, existing studies need a lot of calculation time for reconstructing data distributions if the number of user attributes is large. We prove out proposed method is effective by mathematical analysis and simulations.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会"}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://id.nii.ac.jp/1001/00103084/","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2014 Information Processing Society of Japan. 本著作物の著作権は情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1882-7764","subitem_source_identifier_type":"ISSN"}]},"item_10001_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":"清, 雄一","creatorNameLang":"ja"},{"creatorName":"セイ, ユウイチ","creatorNameLang":"ja-Kana"},{"creatorName":"Sei, Yuichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大須賀, 昭彦","creatorNameLang":"ja"},{"creatorName":"オオスガ, アキヒコ","creatorNameLang":"ja-Kana"},{"creatorName":"Ohsuga, Akihiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-05-15"}],"displaytype":"detail","filename":"IPSJ-JNL5509018.pdf","filesize":[{"value":"4.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"IPSJ-JNL5509018","url":"https://uec.repo.nii.ac.jp/record/9201/files/IPSJ-JNL5509018.pdf"},"version_id":"d5269746-c72f-4f3b-bbcf-a249b9765ac1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"プライバシ","subitem_subject_scheme":"Other"},{"subitem_subject":"データマイニング","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"多次元属性のための匿名データ収集アルゴリズムの提案","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"多次元属性のための匿名データ収集アルゴリズムの提案","subitem_title_language":"ja"},{"subitem_title":"Anonymized Data Collection for Multi-dimensional Attributes","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"13","path":["6"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2019-05-15"},"publish_date":"2019-05-15","publish_status":"0","recid":"9201","relation_version_is_last":true,"title":["多次元属性のための匿名データ収集アルゴリズムの提案"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2024-03-04T04:39:02.634335+00:00"}
