であった．また先行研究では英語文章の入力を前提とした推定モデルの構築と評価のみが行われており，英語以外の言語に対する有効性は明らかになっていない．そこで，本研究では Keyboard Acoustic Emanations に対して自然言語処理モデルである BERT モデルを適用することで単語間の繋がりを考慮し，自然言語テキストに対する推定精度を向上させる手法を提案する．評価実験によって提案手法が英語と日本語の入力文章に対して高精度で推定可能であることを示し，得られた知見に基づき有効な対策方法について議論する．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告セキュリティ心理学とトラスト（SPT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-02-28","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"17","bibliographicVolumeNumber":"2022-SPT-46"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:17:10.892382+00:00","updated":"2025-01-19T15:46:39.183736+00:00"}
