Although watermarking is a useful technique for guaranteeing the integrity of evidential audio data, distortion of sound quality must be prevented. A reversible digital watermarking technique based on the human auditory system was conventionally proposed to embed feature data for tamper detection in the high-frequency coefficients. However, this technique has the drawback that spectral analysis can reveal the embedding locations. This research explored variable embedding locations while preserving good sound quality.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"997","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2024論文集"}],"bibliographicPageStart":"992","bibliographicIssueDates":{"bibliographicIssueDate":"2024-10-15","bibliographicIssueDateType":"Issued"}}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":240879,"links":{}}
