Abstract(in English) A personal computer (PC) radiates electromagnetic noise unintentionally. It has been reported that the display image screened on the PC can be reconstructed by receiving and analysing the electromagnetic noise. In the information security, the reports indicate very important problem that the electromagnetic emanation from a PC has the possibility of inducing information leakage in the display image. Therefore, the discussions for the evaluation and the countermeasure become an immediate serious issue. In this report, we propose an evaluation method of information signal on display image included in the electromagnetic emanation from a PC. And the availability is shown by the correlation with the quality of the reconstructed image and the level of information signal in our experiments. Our proposal method will be able to evaluate quantitatively the information leakage through the electromagnetic emanation from a PC.
