- 摘要:
- 提出了一种基于图像归一化技术和扩频技术的离散余弦变化零水印方案.首先,分别采用Arnold置乱技术和扩频技术对零水印图像进行处理,以提高水印图像的安全性和鲁棒性; 其次,使用图像归一化技术对载体图像进行处理,将处理后的载体图像分成若干块,并对每个小块进行DCT变换; 最后,把由每个小块的第一个DCT系数所组成的系数矩阵作为零水印嵌入位置.实验表明,本文提出的算法对仿射变换、JPEG压缩、噪声和图像亮度变化等攻击具有很好的鲁棒性.
- Abstract:
- This paper proposes a DCT zero-watermark scheme based on image normalization and spread spectrum technology. First, using Arnold scrambling technology and spread spectrum technology to process the zero-watermark image. Second, using image normalization technology to process the carrier image and dividing it into several blocks, DCT transform will be performed on each block. Third, choosing the first DCT coefficient of each block, which can consist of a coefficient matrix, to be the position of embedding zero-watermark image. Experiment results show that the algorithm is robust to affine transform, noising attack, intensity roughness and JPEG compression attacks.
