基于纹理强度的不等长密钥的零水印算法

Zero Watermarking Algorithm Based on Texture Intensity with Unequal Key Length

基于图像纹理强度特性,提出了一种基于图像纹理强度的不等长密钥的零水印算法,在一定程度上可以抵抗JPEG压缩攻击、剪切攻击、缩放攻击、噪声攻击、滤波攻击等攻击,并能有效地提取水印。生成的密钥不容易被破解,具有较高的安全性。

Based on the image texture intensity property,a zero watermarking algorithm with unequal key based on image tex⁃ture intensity is proposed,which can resist JPEG compression attack,clipping attack,scaling attack,noise attack,filtering attack and other attacks to a certain extent,and can extract watermark effectively.The generated key is not easy to be cracked and has high security.
