摘要: 提出了一种新的基于置乱变换的多重数字水印盲算法。该算法具有以下性能:(1)可嵌入多重水印,标志不同所有者(如创作者、发行者、使用者等)版权使用的合法信息;(2)水印的隐藏效果好,多重水印的嵌入不会造成视觉质量的严重下降;(3)水印的嵌入和提取过程中需要个人密钥,不知道密钥的非法使用者无法正确提取水印;(4)水印的嵌入位置只依赖于密钥,与算法无关,非法用户无法知道水印的嵌入位置;(5)水印的提取无需原始图像和原始水印;(6)可以抵抗LSB攻击和剪切攻击。

Abstract: This paper proposes a new kind of multi-blind digital watermark algorithm based on image scrambling. The features of presented algorithm to embed the watermark are: (1)Multiple watermarks can be embedded to mark different owners; (2)The difference between the watermarked image and the original image is perceptually invisible; (3)Using a secret key in the procession of embedding and extracting the watermarks; (4)The position of embedding only depends on the secret key; (5)Extracting of the embedded watermarks do not need the original image and original watermarks; (6)The watermarks are robust against LSB and crop attack.
