Chinese Scientists Have Hijacked Whale Song to Send Secret Military Messages

Chinese scientists have found a way to hide secret messages in the sound pulses that sperm whales emit to keep enemy reconnaissance systems from deciphering them – a breakthrough that could help military submarines avoid scrutiny, researchers said.

With this technique, whale sounds are edited and a coding system is built around them. Messages are emitted in the form of these edited whale sound bites, indistinguishable from regular whale sound, which are deciphered by the receivers following the code.

How would they help subs avoid detection. All that the technology being touted is a communications encipherment tool. It most definitely not is methodology for hiding a sub from detection or creating a "stealth" sub. So it appears to be what some politicians call fake news.

Well it’s as trustworthy as any news out of China.

But the theory seems pretty sound to me. Anti sub listening technology filters out whale song and other background sea noise. So if you modulate your sub-ship comms to sound like whale song it will be filtered out and missed.

The leads scientist did say it would only be successful for a short while until the enemy identified it and countered.

My thoughts are it would be useful as a sub distress call in combat operations. When you don’t want the boat to fall into enemy hands.

This is an absolute load of rubbish and yes fake news. Why ? because the transmission and method of transmission is of no relevance whatsoever. What does count is your cryptography !

The whole supposed stealth of this method is now shot because they have told people about it, so if it were true and they do use it, it is a very simple matter of adding it to the mix, it would be very very easy to distinguish the difference between a real whale and a fake, the obvious one being that fact that it would have to be a synthesized or digitised sound, the embeded code would need markers, and depending on ocean conditions, temps, depths etc the variation on transmission distances would make the entire system pretty much useless.

As for the comms and methods that subs use, how they are employed etc, well I won't be going into that in an open forum. So nice try China, but BZZZZZZZZ
Try again :)

A few years ago in another similar discussion I provided a better link Im unable to find naming the sealife and the effect it gave at night due to submarine passage
the above link also provides some evidence of it
