Reply to comment by nybble41 in A group of researchers has achieved a breakthrough in secure communications by developing an algorithm that conceals sensitive information so effectively that it is impossible to detect that anything has been hidden by thebelsnickle1991

For one, steganography systems do not universally assume that. There are plenty of use cases for hiding data in plain sight, commonly used images, etc. Hiding data in a common image might be plenty to slip it past a censor or authority even if a later cryptanalysis might detect it.

But please link me the mathematical proof that backs up their claim that this is "perfectly secure" (whatever that actually means). "Random seeming" is not random. Even tiny biases can tip off attackers that there may be encrypted data, no matter how many times you XOR it. Random is random, everything else has patterns. No matter how cleverly they intermingle it with other structured data, it is not random and I'm not buying it unless they have a peer reviewed proof that backs their claim up.
