| Abstract: | The electromagnetic radiation will result in information leakage when computers work. This paper presents the recognition technology of information leakage caused by video signal electromagnetic radiation. To get the intact and useful information of video signals conveniengtly, the pattern recognition method based on artificial neural networks is proposed. In the last part, the primary word image recovered from the electromagnetic leakage is recognized and reconstructed and the recognizability of the information leakage from computers is discussed. |
