- borism 15y agoSteganography doesn't hide existence of communication, it hides/obscures existence of messages in it. Important distinction.
- ksolanki 15y agoSteganography hides the existence of covert communication. The message is hidden in an innocuous looking host (say a picture or video that noone would get suspicious about). So in that sense, the existence of actual communication is not known to a third party. I did a PhD theses on this topic :)
