Abstract

A risk of eavesdropping the screen image of a device by exploiting unintended electromagnetic (EM) emanation is reported. Estimating the source of EM emanation from the device is an efficient method to protect the device from eavesdropping by use of EM shield to reduce unintended EM emanation. The authors estimated, multiple EM emanation sources by observing the EM distribution at leakage frequencies of a tablet and a display monitor. The mersurement, showed estimation of the EM emanation sources such as a cable that connects LCD panel to the integrated circuit in the tablet, HDMI cable, and the edge of the screen.
