Wire-tap channel concept in nature and society

The notion of abstract wire-tap channel concept (WTCC) has been proposed by A. Wyner in 1975 and it was later developed by many researchers. This concept executes special randomized encoding in order to prevent information leaking over the wire-tap channel while maintaining a reliable information transmission over the main channel. The difference between the wire-tap and the main channel is in a different level of noises in these channels or an existing of feedback channel as a part of the main channel. We present a short review regarding the main results of WTCC and its applications in communication engineering. But the goal of this paper is to “go back to nature and society” and to try to find some examples of this concept presence in nature and society. We show that among such examples it is possible to count the camouflage in the animal kingdom, the genetic code, and natural languages. We are unable to present rigorous total proofs of the WTCC presence in the mentioned phenomena, but we hope to motivate the IT community to find some new examples of such presence in both nature and society.
