摘要
音频作品被非法篡改会导致作者利益受到侵害,因此音频水印嵌入提取算法的研究在数字产品版权保护中具有重要的研究价值。针对音频水印的特性及评价进行分析,分别基于离散小波变换、离散余弦变换以及DWT-DCT-SVD等算法,重点研究音频水印评价标准中透明性和鲁棒性问题。考虑相同音频及水印,针对不同的嵌入提取算法从透明性及鲁棒性两方面进行对比分析。结果表明,DWT-DCT-SVD算法在透明性及鲁棒性方面更具优势,为数字产品版权保护中音频水印算法的选择、应用及优化提供了重要的理论及应用依据。
Because the audio works are tampered with illegally,the interests of the publishing author will be harmed,so the research of audio watermark embedding extraction algorithm has important research value in the copyright protection of digital products.This paper analyzes the evaluation criteria of audio watermarking algorithm.Based on discrete wavelet transform,discrete cosine transform and DWT-DCT-SVD algorithms,the transparency and robustness of audio watermarking evaluation criteria are studied.Considering the same audio and watermarking,different embedding extraction algorithms are compared and analyzed from transparency and robustness.The results show that DWT-CT-SVD algorithm has more advantages in transparency and robustness,which provides an important theoretical and application basis for the selection,application and optimization of audio watermarking algorithm in digital product copyright protection.
