Snooping Through Walls with Microwaves

denis-The-menace writes "According to an article from newscientist, scientists have devised a system to use microwave energy for surveillance. If people are speaking inside the room, any flimsy surface, such as clothing, will be vibrating. This modulates the radio beam reflected from the surface. Although the radio reflection that passes back through the wall is extremely faint, the kind of electronic extraction and signal cleaning tricks used by NASA to decode signals in space can be used to extract speech. Although, I doubt it would work in this room"

    I think I'm going to buy stock in Alcoa Operations...with shenanigans like this going on, they can only increase in value.

    In the meantime, here's some telltale signs you might be under microwave surveillance:
    • You feel slightly warmer than is normal.
    • Your food seems to be cooking itself.
    • Metal objects in your house give off sparks for no good reason.
    • Your coffee remins hot for a very long time.
    • Your beer remains cold for a very short time.
    • All your CDs are covered with tiny cracks and will no longer play.
    • Your house pets smell delicious.

    Watch for these signs and protect your privacy...cause the government certainly isn't going to.

    You're right. The foil will have to be glued to the wall sheeting, egg cartons to the foil, another layer of foil over the egg cartons.

    Yeah, they listen to the music playing inside your house. Say you are hearing the latest hit from Britney Spears but the RIAA has no record of you buying it, well they turn the 'volume' to 11 on their microwave emitter and fry your balls, burn your house and kill your dog. Justice has been served, right?

    A microwave device can be defeated by the good old tinfoil hat - by which I mean wallpapering in foil or otherwise turning the room into a faraday cage.

    I'd suggest lining the walls with bags of popcorn. That way you'll know when you're under survellance and have a nice snack readily available.
