摘要 为提高回声隐藏方法中水印信息的提取效果和准确率,在原始载体基本不变化的基础上加大水印信息的嵌入量,提出了一种使用双向回声核来增加隐藏效果和嵌入量并对水印信息进行BCH编码以利于提高提取准确率的方法,利用功率倒谱方法来确定水印嵌入位置便于增加水印信息的提取率。仿真实验结果表明,该方法算法简单、执行效率高、水印隐藏效果好,在受到恶意攻击后提取出的水印信息的准确率远远高于原方法。 To improve the extraction and accuracy of watermark information from echo hiding, two-way echo kernel method is proposed, which can increase the hidden effects and the amount of watermark information embedded based on almost no change in the original carrier. The watermark information is encoded by BCH to facilitate the extraction of hidden information. The em- bedding location of watermark information determined by the power cepstrum, thus can improve the extraction rate of watermark information easily. The simulation results show that the algorithm is simple, the implementation is efficient, the watermark hidden effect is good, the accuracy of the watermark information extracted after malicious attacks is much higher than the original method.
