基于伪随机序列的数字图像水印设计与实现

According to the Digital Picture Watermark Design and Realization of the Pseudo-random Sequence

用一种基于伪随机序列的水印实现方法,对需要保护的数字图像作品进行防伪水印的嵌入与检测研究,嵌入到作品中的水印信息与嵌入位置相关联,不易被人为攻击。

An associated pseudorandom sequences technique,which is used in encryption watermark embedding and detecting,is researched for multimedia copyright protection.It makes the embedded data associate with the embedded position,so the watermark is not easy to be attacked.Covariance is used to detect watermark,which may reduce the influence of initial data or chaos in partially.The discussion of the watermark s hidden ability and robustness。
