つの波を標的のマイクに一致する点で交差させることにより，可聴音が聞こえる範囲を極小化する．その攻撃を X (Cross) - Audio Attack と名付け，その特性と有効性を主観評価実験により評価する．また，このような音声認識デバイスを標的にした攻撃への汎用的な対策手法として，超音波から発生する音声，ダイナミックスピーカが発生する音声，および人間の肉声を見分ける識別器，Voice Liveness Detector を提案する．作成した識別器の性能評価を行い，これまでに提案された音声認識への攻撃全てを検知でき，かつ高精度で攻撃検知が可能であることを示した．","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"24","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2018論文集"}],"bibliographicPageStart":"17","bibliographicIssueDates":{"bibliographicIssueDate":"2018-10-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"2018"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T00:57:51.597343+00:00","id":192098,"links":{}}
