盗版是内容行业的一个主要问题，尽管数字技术提高了新内容生产的效率，但盗版也加速了他们的盗版。商用相机已经足够好，可以重新拍摄屏幕上显示的图像，电视显示器越来越大，图像质量也越来越好；这种组合将使内容在不久的将来能够在家庭中被盗版。用商用相机重拍是最终的盗版方法，因为没有任何工程方法可以阻止它。我们开发了一种新的水印方法，即使在显示器上显示的图像被重新拍摄后也能保留。本文介绍了该方法的原理和实验结果。
Piracy is a major issue in the content business, and although digital technologies raise the efficiency of new content production, pirates also accelerate their piracy. Commercial cameras have become sufficiently good to re-shoot images displayed on screens, and TV monitors are becoming larger with better picture quality; this combination will enable content to be pirated in the home in the near future. Re-shooting with a commercial camera is the ultimate piracy method because there is no engineering way to stop it. We have developed a new watermark method that remains even after images displayed on a monitor have been re-shot. This paper describes the concept and experimental results.
