基于视觉效应的视频信息电磁泄漏抑制方法研究
Research on Method for Preventing Digital Video Signal Electromagnetic Leakage Based on Visual Effect
摘要
Abstract
The electromagnetic radiation of computer contains video information which causes the information leakage.In this paper,a method is proposed according to the effect of human visual,based on the random scrambling,which called complementary scrambling,for preventing the leakage of video information through the electromagnetic radiation.The effect of human visual can eliminate the interference of noise to video image by adding and subtracting the random noise to each contiguous frame of video information,and imposes noise on displayed screen images while keeping the quality of the image.And realize the function of preventing the video information electromagnetic leakage.Finally,the feasibility of the method is verified by experiments.关键词
