Abstract

It is known that the display image on a personal computer with a monitor can be reconstructed by receiving the electromagnetic noise. Recently, the concern about information leakage in the display image caused by the electromagnetic noise has increased from the aspect of information security. In the present study, the information leakage of input button key operations on touch screen monitors was investigated experimentally in the reconstructed display image using the received electromagnetic noise. The experimental results revealed that the touched button image on the touch screen monitor can be identified in the reconstructed display image. In addition, the information leakage origin was discussed based on the reconstruction principle of the display image.
