我们提出了一种方法，用于防止非法重新录制的图像和视频与数码摄像机。传统的数字水印技术涉及将内容ID嵌入到图像和视频中，这有助于识别实际内容被记录的地点和时间。然而，数字水印技术并不能控制用便携式摄像机非法重新记录数字内容。所提出的方法通过在记录期间使用CCD或CMOS器件用不可见的噪声信号破坏所记录的内容来防止这种重新记录。这样，重新记录的内容将不可用。为了验证所提出的方法的结果，我们开发了一个功能的原型系统，用于防止非法重新记录，并实现了它在100英寸的电影屏幕上。
We propose a method for preventing illegal re-recording of images and videos with digital camcorders. Conventional digital watermarking techniques involve embedding content ID into images and videos, which helps to identify the place and time where the actual content was recorded. However, digital watermarking technology does not control the illegal re-recording of digital content with camcorders. The proposed method prevents such re-recording by corrupting the recorded content with an invisible noise signal using CCD or CMOS devices during recording. In this way, the re-recorded content will be unusable. To validate the results of this proposed method, we developed a functional prototype system for preventing illegal re-recording and implemented it on a 100-inch cinema screen.
