| 摘要: |
| 为了找到一种能够抵抗旋转攻击的安全的水印算法,综合分析了常见的水印算法后,发现离散小波变换、离散余弦变换、奇异值分解的变换域水印能够较好地满足抗旋转攻击的需求。对水印图像进行了双随机相位全息加密,通过密钥保障水印的安全性,把加密的水印嵌入到变换域中。设计了试验,研究了含有水印的图像在平移、缩放、旋转、中值滤波、高斯噪声、椒盐噪声和压缩攻击下提取水印质量的影响。实验结果表明,水印能够抵抗常见的几何攻击,特别是旋转攻击,对常见的噪声压缩攻击同样有很好的效果。基于变换域的全息水印算法具有很好的鲁棒性,能够抵抗常见的几何攻击,具有很好的安全性,没有密钥不能对水印进行检测和去除。 |

| Abstract: |
| Commonly used watermarking algorithms were analyzed. It was founded that discrete wavelet transform, discrete cosine transform, and singular value decomposition can meet the demand of resisting rotation attacks and double random phase encrypted holographic technology can meet demand of security. Holographic watermark image was embedded into the transform domain. The influences of rotation, scale, translation, median filter, Gaussian noise, salt and pepper noise, and JPEG compression on the quality of extracted watermark image were studied by experiments. The result showed that the holographic digital watermarking technology based on transform domain can resist common geometric attacks, especially rotation attacks, and effective to resist common noise and compression attacks. It was concluded that the watermarking technology is of both robustness and security. |
