描述了一种防止使用数码相机和摄像机非法记录屏幕上显示的视频和电影的方法。传统的保护方法，例如在图像中嵌入数字水印以用于识别原始内容被非法记录的地点和时间，实际上并不能防止内容被非法记录。建议的方法基于人和设备之间感觉特征的差异，实际上防止了非法记录。它不需要向用户端设备添加功能；相反，它使用红外线来破坏记录的内容。这种光是肉眼看不见的，但会被相机中的ccd或cmos器件捕捉到。这会使录制的内容无法使用。使用在100英寸影院屏幕上实现的功能原型进行的测试表明，该方法有效地防止了非法录制。还描述了一种针对使用装有红外切割滤光片的照相机或摄像机的有效对策。
A method is described that prevents videos and movies displayed on a screen from being illegally recorded using digital cameras and camcorders. Conventional protection methods, such as embedding digital watermarks into images for use in identifying where and when the original content was illegally recorded, do not actually prevent the content from being illegally recorded. The proposed method, which is based on the differences in sensory characteristics between humans and devices, actually prevents illegal recording. It does not require the addition of a function to the user-side device; instead, it uses infrared light to corrupt the recorded content. This light is invisible to the naked eye but is picked up by the CCD or CMOS device in the camera. This makes the recorded content unusable. Testing using a functional prototype implemented on a 100-inch cinema screen showed that the method effectively prevents illegal recording. Also described is an effective countermeasure against the use of a camera or camcorder fitted with an infrared cut filter.
