"But the problem with reincarnation is that it's hard to imagine what the storage medium for past lives would be. Not to mention the input-output device. I hesitate to rule it out completely, but I'd need pretty definite proof."
- Arthur C. Clarke

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.
