| 摘 要： | 提出一种新颖的图像水印认证算法，利用量化的方法可以获得被保护图像的指纹信息，这部分信息被用来对给定图像进行认证．指纹信息的嵌入和抽取并不会影响到图像的质量．实验表明，该算法具有较好的图像认证能力，能够识别大多数对被保护图像进行的攻击． |
| 关 键 词： | 半脆弱性 数字水印 图像认证 鲁棒性 |

| Abstract: | A novel semi-fragile watermarking scheme for image authentication was proposed. The finger-print information of the whole image was extracted following the idea of quantization in both spatial domain and frequency domain respectively, and this information was used for the image authentication. The fingerprint information extraction had no influence on the protected image. The experimental results showed that the proposed scheme had good authentication ability under general image processing and malicious attacks. |
| Keywords: | semi-fragile digital watermarking image authentication robustness |
