不存在的数字图像隐写算法这将是耐图像处理？ [英] Does there exist a digital image steganography algorithm which would be resistant to image manipulation?

问题描述

我不知道 - 是有数字图像的隐写的解决方案能够抵抗图像操作？随着操纵我的意思是最标准的操作 - RECOM pressing JPEG文件（甚至是改变文件格式完全），裁剪和缩放。这种方法的应用自然会进行图像的版权保护。

I'm wondering - is there a steganography solution for digital images which is resistant to image manipulations? With "manipulations" I mean the most standard operations - recompressing JPEGs (or even changing file formats entirely), cropping and scaling. The application of this method would naturally be for image copyright protection.

我完全理解，更多的图像操纵少是机会，隐写的水印是完整的，但至少一定程度的阻力将是很好的。

I fully understand that the more image is manipulated the less are the chances that the steganographic watermark is intact, but at least some degree of resistance would be nice.

推荐答案

在我看来，这只是另一种的猫捉老鼠的游戏之举，但在这里你是：

It seems to me, that this is just another move in the cat and mouse game, but here you are:

从结论：

总是会有在水印嵌入的折衷。我们的意思水印经文的图像劣化的鲁棒性之间的折衷。在一些点，水印的强度会造成图像被降解到一个点，这将是不能接受的。

"There will always be a tradeoff in watermark embedding. By which we mean tradeoff between robustness of the watermark verses the degradation of the image. At some point the strength of the watermark will cause the image to be degraded to a point, which will not be acceptable.

根据用于水印，无论是在空间域或频域的技术中，水印图像显示，在一般情况下，鲁棒性相同的域和虚弱以相反域的攻击的攻击。中村提到这些结果在他的工作，并得出结论，有没有一种方法，将在这两个领域强劲，而且采用的混合水印算法将有更坏的结果。

Depending on the technique used for watermarking, whether in spatial or frequency domain, the watermarked image showed, in general, robustness to the attacks of the same domain and weakness to the attacks in the opposite domain. Nakamura mentions these results in his work, and concludes that there is no method that will be robust in both domains, and that applying hybrid watermarking schemes will have worse results."
