摘要

提出了一种基于离散余弦变换(DCT)域的音频水印算法。水印嵌入过程依赖于概率密度函数(pdf)建模。该方法能够保证弱水印在受到噪声添加和压缩等常见攻击时仍能得到最优检测。用信噪比(SNR)来评价该技术的性能。

A new audio watermarking method with optimal detection

A new audio watermarking algorithm based on Discrete Cosine Transformation (DCT) domain is presented. Watermark embedding procedure relies on probability density function (pdf) modeling. The proposed method ensures optimal detection for weak watermarks even when they are exposed to some common attacks such as noise addition and compression. The performance of this technique is evaluated in terms of Signal to Noise Ratio (SNR).
