"[Science fiction] is the only kind of writing that allows you to look at the world we live in and change one piece at a time."
- Frederik Pohl

Anti-Spying Device  
  Foolproof means of defending against spy beams.  

It was not a large office, but it was quite spy-proof and quite undetectably so. Spy-beams trained upon it received neither a suspicious silence nor an even more suspicious static. They received, rather, a conversation constructed at random out of a vast stock of innocuous phrases in various tone and voices.
From Foundation, by Isaac Asimov.
Published by Doubleday in 1951

Compare to the cone of silence From Cease Fire (1958) by Frank Herbert, hush corner by Robert Heinlein in Double Star and the Fenton Silencer from an early Arthur C. Clarke story.

The earliest example I know of is the isolation barrage from Wandl, The Invader (1939) by Ray Cummings.
