A possible information leakage from DVI cable corresponding to display color

In this paper, the possibility about information leakage from digital visual interface (DVI) cable for color display is analyzed. The principle of information leakage form DVI cable, which already documented before, is reviewed. The electromagnetic emanations from DVI cable are measured for several cases of color display which have different color combination. Also, it is shown that the legibility of recovered image is different with respect to the color combination.
