I thought this bounced since i didnot receive a copy, hence resending. apologies if you already received it. hi, I came across this link through this months Cryptogram. http://oculislabs.com/Products/ChameleonP.htm The link reads.... "Oculis Labsb Chameleon System protects your monitor against eavesdropping. With Chameleon running, you can read your screen normally, but no one else can. Chameleon protects against the shoulder-surfing eavesdropper as well as opponents using sophisticated TEMPESTbtype electronic surveillance." I am curious to know how it prevents TEMPEST?

Any insight is welcome. Thank you, Sarad AV
