摘要
数字音频水印技术是一种利用特定标识信息嵌入到数字音频内容中的技术手段,它能够实现版权保护和内容取证的功能。为了同时满足版权保护和内容取证的需求,给出了一种基于保密特征的水印嵌入量化方法,并构造了一种基于该保密特征的数字音频双水印算法。将水印嵌入在保密特征中,有效提高了水印系统的安全性。同时,该算法能够实现版权保护和音频内容取证,提高了其实用性。实验结果表明,该算法具有良好的不可听性、鲁棒性、安全性及对恶意攻击的检测能力。
Digital audio watermarking technology is a technique for embedding specific identification information into digital audio content,which can be used for copyright protection or content verification.To meet the needs of both copyright protection and content verification,a quantization method based on confidential features was proposed,and a dual watermark algorithm for digital audio based on this feature was constructed.By embedding the watermark in the confidential feature,the security of the watermark system was effectively improved.Moreover,the algorithm could achieve both copyright protection and audio content verification,enhancing its practicality.The experimental results indicated that the algorithm had good imperceptibility,robustness,security and detection ability against malicious attacks.
