讨论了多媒体信息可靠性鉴定的数字水印方法，可靠性鉴定也称为篡改证明。
We consider the problem of digital watermarking for credibility authentication or tamper proofing of multimedia.
硬件篡改证明是可能的，并且可能有效防止复制(虽然它不是没有错误)，但其缺点还是实际应用太昂贵。
Hardware tamper proofing is possible and tends to work quite well for preventing duplication (though it is not infallible), but on the downside it is also quite expensive to place in practice.
以证明它在一个未被篡改环境中运行的能力。
他篡改了实验结果以证明他的理论。
实验证明该算法对固定系数的JPEG压缩有较好的鲁棒性，并对图像的恶意篡改有较好的脆弱性。
The experiments results show that this algorithm has a good robustness for the JPEG compression with the fixed coefficient, and a good fragileness for the illegal manipulation.
文章将图像的模糊估计和传感器的模板噪声检测篡改的方法结合起来，对多幅图像操作，实验证明有不错的检测效果。
This article USES blur estimation and sensor noise to detect forgery. The performance of the proposed method is demonstrated on several forged images and has been proved to have good effect.
大量的实验结果证明，该脆弱水印算法对篡改有极强的敏感性，且当小波参数不一致的情况下，则完全不能检测正确的水印信息。
Lots of simulation results show that the weak watermark is sensitive to the distortion of the image. When the parameter in the wavelet is wrong, the watermark cannot be detected correctly.
