提出了一种基于音频特征和逼近信号统计特征的零水印算法.实验结果表明,该算法能根据音频自身的特点寻找到适合用于嵌入水印的音频帧,实现水印信息的嵌入、提取和盲检测,在不改变听觉质量的同时降低了计算量,提高了水印的鲁棒性.
An zero-digital watermark algotithm based on audio features and statistical feature of approximation signal is presented. Experimental results show that the proposed algorithm can find the suitable audio frames to embed watermark according to the characteristics of the audio signal and can achieve watermark information embedding, extraction and blind detection. Reducing the computation and improving the robustness of watermarking system without losing auditory quality.
