基于小波包分析的数字音频双水印算法

摘要

Robust watermark can be designed for copyright protection of audio works based on zero watermark.The fragile watermark,using mean quantization block embedded in half,can be used to identify the content of audio works.The two -dimensional image block during the process mentioned above does not need to be converted into the one-dimensional sequence,which is different from previous algorithms in image and an embedding dimension.%基于零水印概念设计的鲁棒水印能够对音频作品进行版权保护；采用均值量化分块嵌入的半脆弱水印，可以对音频作品进行内容认证，此过程中的二维图像块不需要转换为一维序列，有别于以往算法中图像变维并一次嵌入的方法。
