描述了一种用于防止对显示器上所示的信息进行未经授权的复制的方法。它利用了人类和成像设备之间的光谱灵敏度差异。一种对人类视觉没有影响的近红外光源被安装在现有显示器的前面，以破坏从显示器拍摄的照片的内容。使用原型实现的测试表明，该方法有效地防止了未经授权的复制显示的信息。除了防止通过对显示器的未授权拍摄而泄露机密和个人信息之外，所提出的方法还广泛应用于对艺术品、工厂设备和受到摄影限制的其他对象的未授权拍摄。
A method is described for preventing unauthorized copying of information shown on a display. It utilizes the difference in spectral sensitivity between humans and imaging devices. A near-infrared light source, which has no effect on human vision, is installed in front of an existing display to corrupt the content of photographs taken of the display. Testing using a prototype implementation demonstrated that this method effectively prevents the unauthorized copying of displayed information. In addition to preventing the disclosure of confidential and personal information through the unauthorized photographing of displays, the proposed method has broad application to the unauthorized photographing of works of art, factory equipment, and other objects subject to photographic restrictions.
