Abstract
Unintentional electromagnetic waves leak out from a liquid crystal display (LCD) monitor, which is the main output device of a computer. When the leaked signal is recovered, the display information of target monitor can be interpreted. Because leakage electromagnetic waves which include video signal information occur in the hardware system after the video signal processor of the LCD monitor radiation band is dependent on the clock frequency. In this paper, a method to distinguish the leaked information from two target monitors which have different refresh rate is proposed.
