| 目的 寻找一种能够抵抗常见几何攻击的安全的水印算法。 方法 通过分析常见的水印算法,发现傅里叶-梅林变换域水印能够较好地满足抵抗常见几何攻击的需求。 对水印图像进行双随机相位全息加密,通过密钥保障水印的安全性,通过把加密的水印嵌入到傅里叶-梅林变换域的方法,设计对比试验,研究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、 压缩、打印扫描、打印拍摄攻击下提取水印质量的影响。 结果 水印能够抵抗常见的几何攻击,特别对平移、缩放、旋转组合几何攻击、打印扫描和打印拍摄有很好的效果。 结论 基于傅里叶-梅林变换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。 |

| Objective To find a digital watermarking algorithm against geometric attacks and of security. Methods By analyzing commonly used algorithms, it was found that the algorithm based on Fourier-Mellin transform was able to meet the demands of resisting geometric attacks and that the double random phase encrypted holographic technology was able to meet the demands of security. Using the method of embedding holographic watermark image into Fourier-Mellin domain, the influences of rotation, scale, translation, median filter, Gaussian noise, salt and pepper noise, JPEG compression, print-scan and print -shooting on the quality of imaging were investigated by experiments. Results The results showed that the holographic digital watermarking technology based on Fourier-Mellin transform could resist geometric attacks, especially the images taken by a phone or scanner and image attacks by combinations of geometric attacks such as rotation scale and translation. Conclusion The holographic digital watermarking technology based on Fourier-Mellin transform is of both robustness and security. |
