Chinese scientists from Tianjin University have proposed a new way to encrypt secret military messages transmitted underwater. According to New Scientist, they can be disguised as the sounds of dolphins and whales.
Underwater communication becomes more difficult when it comes to secret messages, as they can be detected and intercepted. In addition, the sounds of dolphins and whales usually interfere with military communications. However, these hindrances can be used to their advantage, Chinese scientists are sure.
The trick is that the sounds of marine mammals such as whales and dolphins are usually considered interference, so it is customary to filter them. Accordingly, if the signals are masked for the natural sounds of the inhabitants of the ocean, then no one will be able to detect them.

A group of Chinese scientists, led by Chunyue Li, has already developed a prototype of a technology for transmitting secret signals disguised as the sounds of communication of marine mammals. Experiments have shown that the technology is suitable as an effective tool. The authors of the study are confident that such developments will interest the military from different countries. It is possible that the sounds of whales and dolphins that will fill the ocean in the future will often be artificial.
