摘要
提出了一个使用Legendre序列的语音水印隐藏与检测算法。实验结果表明,用这种算法隐藏水印具有很强的隐蔽性,对原始语音的影响基本上察觉不出来,叠加了水印的语音对于多种强干扰及信号处理均具有很好的健壮性。
A new audio watermark algorithm based on the Legendre Array is proposed in this paper.By using this algorithm,the watermarked speech signal sounds the same as the original one.The digital watermark algorithm can also present a satisfactory robustness,namely the water-mark can be easily detected even though the watermarked speech signal is sorely contaminated,filtered or processed after lossy compression,etc.[
