富士通研究所、暗号化した機密情報の類推を防止する技術を開発
クラウド環境など様々な場所で管理されるデータベースをより安心して使うことが可能に
東京, 2019年10月16日 - (JCN Newswire) - 株式会社富士通研究所(注1)(以下、富士通研究所)は、データベースと検索内容を暗号化したまま照合できる秘匿検索技術を強化し、暗号化されたデータベースから元データの類推を防止することで、より安全に照合できる技術を開発しました。
暗号化されたデータベースでも、公開された統計情報などと比較することで、登録数の一致などから元データを推定される危険性があります。今回開発した技術は、データベースに最小限のダミーデータを追加することで、データベース上の登録数を攪乱し、元データの類推を防止することができます。
これにより、クラウド上など様々な場所で管理される、パーソナルデータ(注2)や機密データ(注3)を暗号化させたデータベースを、さらに安全に活用することが可能になり、組織を横断したデータ利活用の促進が期待されます。
