Abstract
This study verifies the feasibility of information leakage from video cable of digital video display interface. The compromising electromagnetic emanations are estimated by analyzing digital visual interface (DVI) used as video display interface in this research. Leaked signal from DVI cable was measured by near-field probe and digital oscilloscope. Target display is composed with '10' and '55' color as maximum contrast of electromagnetic emanations. Strong frequency band of received signal is near 324 MHz which is related to pixel frequency of target display. Emanated signal filtered with 10 MHz bandwidth at center frequency of 324 MHz is recovered to display. Information leakage from DVI cable at close range is demonstrated by recognizable recovered display.
