PC机的电磁辐射中包含视频信息，可以进行图像重建。在货车埃克的论文发表后，这一点就广为人知了。用于连接显示器和图形控制器的视频电缆原来是泄漏信号的主要来源。对于数字视频接口，并不是所有的彩色图像都可以截取和重建。首先分析了基于数字接口标准的彩色图像重建技术。然后，我们提出了一种方法，改变原始的PGB信号的安全颜色，同时保持图像的质量，利用人类视觉和颜色混合的特点。通过在普通计算机系统的FPGA板上实现该方法，验证了该方法作为电磁视频信息泄漏对策的有效性。
Electromagnetic radiation of PC contains video information, and the image can be reconstructed. It is well known after the Van Eck's paper. The video cable used to connect the display with the graphics controller turned out to be the primary source of the leaking signal. For digital video interface, not all kinds of color images can be intercepted and reconstructed. Firstly we analyzed which color image can be reconstructed based the digital interface standards. Then we propose a method that changes the original PGB signals to safety color, while keeping the quality of the image by using the characteristics of the human visual and color mixing. By implementing this method on FPGA board in an ordinary computer system, we confirmed the effectiveness of our method as a countermeasure for the electromagnetic video information leakage.
