Abstract :
Handheld communication devices fitted with touch-screen LCDs do emit some kind of electromagnetic radiation (EMR) even though they were not designed to do so. There is potential for the emission can be intercepted and reconstructed for eavesdropping or even intelligence purposes. Information leakage from hand-held devices can be valuable information for the intelligence communities. This paper presented discussions on how much unintentional emission is radiated from these devices. Comparison on the level of emission is made based on manufacturers and sizes of LCD.
