【摘要】:計算機的電磁輻射會包含視頻信息從而造成的信息泄漏,本文在隨機置亂的基礎上,根據(jù)人眼視覺效應提出了互補置亂的方法來抑制視頻信息通過電磁輻射的泄漏.通過對相鄰的每幀視頻信息進行加減隨機噪聲,使得人眼視覺觀察效果抵消掉噪聲對視頻圖像的干擾,在疊加噪聲的同時,保證了視頻圖像的清晰度,同樣也達到了抑制視頻信息電磁泄漏的功能.最后也通過實際截獲實驗,驗證了該方法的可行性.
[Abstract]:The electromagnetic radiation of the computer contains the information leakage caused by the video information. Based on the random scrambling, this paper proposes a complementary scrambling method according to the human visual effect to suppress the leakage of the video information passing through the electromagnetic radiation. By adding and subtracting random noise to each frame of adjacent video information, the visual observation effect of human eye cancels the interference of noise to the video image, and the definition of video image is ensured while the noise is superimposed. It also achieves the function of restraining the electromagnetic leakage of video information. Finally, the feasibility of the method is verified by the actual interception experiment.
