Chinese scientists are investigating ways to use giant creatures to help “camouflage” messages sent by the military.
Researchers believe that sperm whales can hide underwater signals sent by Chinese submarines, preventing any nearby enemy from detecting anything at all. Instead, it will simply sound like the natural sound of the ocean.
Sperm whales are extremely social creatures, travel in capsules and use a variety of clicks, whistles and buzzes to communicate.
“When sound waves bounce off an object, they return to the whale, allowing the whale to identify the shape of the object. Clicks can even help differentiate between friendly creatures and predators, “the National Oceanic and Atmospheric Administration (NOAA). describe online.
Like sperm whales, the Chinese army would also like to send signals and warnings if they detect potential threats.
Hiding military messages
Jiajia Jiang, associate professor of the State Key Laboratory of Technology and Precision Measurement Instruments at Tianjin University in China and principal investigator of the project that was published in the IEEE Communication Journal, described two ways in which officials could try to hide Military messages can alter current “man-made” signals to make them more difficult to understand or send “weaker signals” to make them more difficult to discover.
Jiang says the second option is more effective, although there are, of course, pitfalls. The farther the message has to travel, the more likely it is that it will get lost along the way.
“The advantage of steganography over encryption and other conventional methods is that the intended secret message does not attract attention, avoiding scrutiny,” said Han Guangjie, a computer scientist at the Dalian University of Technology in China who was not involved in the study. the investigation. Submit. “Clearly visible encrypted messages, no matter how unbreakable, arouse interest.”
To achieve this, the researchers said they would have to edit the sperm whale sounds to hide the messages within them, while at the same time distinguishing them enough so that the whales do not confuse them with theirs. They would also have to build new technology that would translate the codes for the Chinese army.
While the idea may seem unorthodox, it is not the first time that marine animals inspire the military.
In Ukraine and Russia, for example, dolphins are used to help detect abnormal activity near their limits, the magazine reported previously.
