quote [ Scientists in China have found a way to hide messages in the calls of sperm whales. The discovery could allow the military to use whales to send encoded messages hidden from any eavesdropping enemies. ]
Now just to make the head gear to mount them on freckin whale head's.
Original paper in IEEE Sensors Journal: "Disguised Bionic Sonar Signal Waveform Design With its Possible Camouflage Application Strategy for Underwater Sensor Platforms", Jiajia Jiang, et al.
The covertness of an active sonar is a very important issue and the sonar signal waveform design problem is studied to improve covertness of the system. Many marine mammals produce call pulses for communication and echolocation, and existing interception systems normally classify these biological signals as ocean noise and filter them out. Based on this, a disguised sonar signal waveform design approach with its camouflage application strategy for underwater sensor platforms is proposed by utilizing bio-inspired steganography.

In the past the whales had been able to sing to each other across whole oceans, even from one ocean to another because sound travels such huge distances underwater. But now, again because of the way in which sound travels, there is no part of the ocean that is not constantly jangling with the hubbub of ships’ motors, through which it is now virtually impossible for the whales to hear each other’s songs or messages.
So fucking what, is pretty much the way that people tend to view this problem, and understandably so, thought Dirk. After all, who wants to hear a bunch of fat fish, oh all right, mammals, burping at each other? But for a moment Dirk had a sense of infinite loss and sadness that somewhere amongst the frenzy of information noise that daily rattled the lives of men he thought he might have heard a few notes that denoted the movements of gods. |

The first rule of steganography is YOU DON'T TELL PEOPLE YOU'RE DOING IT.

The second rule of steganography is A COMPLETELY INNOCUOUS PHOTO OF A KITTEN.
