As a result, the demand of discovering knowledge from the bigdata by using tools such as statistical analysis and data mining naturally become higher. Using MapReduce a software framework introduced by Google in 2004 to implement computations on clusters of commodity computers is an economical solution. However, malicious MapReduce framework or source codes can leak the sensitive data through computation process. An approach which giving user the least privilege on MapReduce-based system can solve the problem. Therefore, in our research, we propose a MapReduce-based system limiting the access to system resource by using SELinux. Moreover, noise were added to the output of the Reduce to ensure the computational result can not signal the presence of a sensitive data. Our prototype implementation demonstrates the efficiency of preserving privacy on several cases.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"8169","nameIdentifierScheme":"WEKO"}],"names":[{"name":"チャン, クワン"}]}]},"item_7_select_21":{"attribute_name":"学位","attribute_value_mlt":[{"subitem_select_item":"master"}]},"item_7_subject_13":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"007","subitem_subject_scheme":"NDC"}]},"item_7_text_24":{"attribute_name":"研究科・専攻","attribute_value_mlt":[{"subitem_text_value":"工学系研究科電気系工学専攻"}]},"item_7_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院工学系研究科電気系工学専攻"},{"subitem_text_value":"Department of Electrical Engineering and Information Systems, Graduate School of Engineering, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Tran, Quang"}],"nameIdentifiers":[{"nameIdentifier":"8168","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":"2017-05-31"}],"displaytype":"detail","filename":"37106530.pdf","filesize":[{"value":"674.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"37106530.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/3397/files/37106530.pdf"},"version_id":"3a637d5c-cdf3-44d6-a128-85f3e9602763"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"A Solution For Privacy Protection In MapReduce","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A Solution For Privacy Protection In MapReduce"}]},"item_type_id":"7","owner":"1","path":["234","271"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-05-18"},"publish_date":"2012-05-18","publish_status":"0","recid":"3397","relation_version_is_last":true,"title":["A Solution For Privacy Protection In MapReduce"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:45:05.698023+00:00"}
