摘    要:提出了一种新的水印嵌入方案,兼顾稳健性和隐蔽性,在载体信号的中频分量上迭加伪随机系列。该方案利用载体数据与伪随机系列相关系数的大小关系负载水印信息,因此嵌入的比特数远远大于迭加的伪随机系列数,提高了水印性能。另外给出了隐蔽性、稳健性、嵌入量与系统参数的关系。

关 键 词:图像处理  数字水印  多比特嵌入

Abstract:A novel watermarking scheme for digital image is proposed, in which pseudo-random sequences are added into the middle frequency components of host signal with the consideration of robustness and imperceptibility. This scheme uses the comparison of correlations between the host data and pseudo-random sequences to carry the watermark, therefore providing a payload significantly more than the number of added sequences. The relations between robustness, imperceptibility, payload and system parameters are also given.
Keywords:Image processing   Digital watermarking   Multi-bit embedding
