Could a one time pad be used to make a spy tape recorder or camera?
It would work like this. At the spy's home base two identical
(digital?) tapes are make containing random noise. Then the spy goes
into the field with one tape recording things
by XORing information onto the tape.
If he is every stopped the tape looks completely random so no one
can prove that he was spying or tell what he recorded.
If the mission is successful he sends the tape back to
base where they decode it with the other tape.
