As a technique to realize this tabulation,Reconstruction method is known. However, this technique has a memory efficiencyproblem when a DB has many attributes. As solutions to that problem, some methods are conceivable,but in contrast, time efficiency becomes problem with these methods. In this paper,we propose a method to solve these problems using GPU, which is a parallel processing device."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1070574047097338754","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000287150410"}],"foaf:name":[{"@value":"永井, 彰"},{"@value":"五十嵐, 大"},{"@value":"松林, 達史"},{"@value":"山本, 剛"}]},{"@id":"https://cir.nii.ac.jp/crid/1070583790078139522","@type":"Researcher","foaf:name":[{"@value":"Akira, Nagai"},{"@value":"Dai, Ikarashi"},{"@value":"Tatsushi, Matsubayashi"},{"@value":"Go, Yamamoto"}]}],"publication":{"prism:publicationName":[{"@value":"コンピュータセキュリティシンポジウム2009　(CSS2009) 論文集"}],"dc:publisher":[{"@value":"情報処理学会"}],"prism:publicationDate":"2011-10-12","prism:volume":"2009","prism:startingPage":"1","prism:endingPage":"6"},"url":[{"@id":"https://ipsj.ixsq.nii.ac.jp/records/74899"},{"@id":"http://id.nii.ac.jp/1001/00074899/"}],"foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=%E3%83%97%E3%83%A9%E3%82%A4%E3%83%90%E3%82%B7%E3%83%BC%E4%BF%9D%E8%AD%B7%E3%81%A8%E5%B1%9E%E6%80%A7%E7%AE%A1%E7%90%86","dc:title":"プライバシー保護と属性管理"}],"dcterms:subject":[{"subjectScheme":"Other","notation":[{"@value":"プライバシー保護と属性管理"}]}],"dataSourceIdentifier":[{"@type":"IRDB","@value":"oai:irdb.nii.ac.jp:02902:0003164868"},{"@type":"CIA","@value":"170000066056"}]}
