随着现代信息技术的高速发展,人们对信息技术的要求越来越高。对我们所需要的信息的安全性、保密性、版权所有性更加的关注。基于此,数字水印技术就应用而生。数字水印技术就是把一些隐藏的信息嵌 。入到数字信息的载体中,数字水印技术把这些信息从一种形式转换为另一种形式,就类似于把信号从时域转换为频域后再去处理问题。数字水印可分为盲水印和非盲水印, 非盲水印系统在检测或提取水印信息时,需要原始图像而且还会影响到人们的视觉感应;盲水印系统在检测或提取水印过程中,既不需要原始载体图像,也不需要嵌入的水印,因此盲水

基于DCT域的数字水印算法主要包括水印调制、水印嵌入和水印提取,首先在嵌入载体图像之前用Logistic混沌序列对水印进行调制,得到一个只有+1和-1随机序列的水印,同时将载体图像进行全局DCT变换,然后将水印图像嵌入人类视觉系统最重要的部分,即DCT最大的系数,DC(Direct Current)部分也包含在这最大的系数中,这部分的系数满足人类视觉特性,会使水印嵌入的性能更好。嵌入算法是将水印与这些系数进行相乘获得新的系数,再用新的系数来替换原来的系数,即获得嵌入水印后的离散余弦域的图像,然后
