Wikipedia disagrees with you ...https://en.wikipedia.org/wiki/Steganography?wprov=sfti1
Steganography is a form of security
Via obscurity :)

Except...you can't know who all has gotten copies

Steganography is used for security
Maybe it shouldn't be ...but it is

And then you gett he problem of security by obscurity .. "as long as no one knows how we did it, it's secure!"

someone can
The sender, for example

You have to have the unaltered originals somewhere, or you won't know what you hid where

>Besides being perfectly secure, the new algorithm showed up to 40 per cent higher encoding efficiency than previous steganography methods, they said.
Sorry, but extraordinary claims require extraordinary evidence
If you're altering a source file (by adding information, as in this example), it's detectable
Cryptographic hashes are a perfect test for this type of communication - the hash of the original will never match that of the altered copy
The only "perfectly secure" communication is a true one-time pad ...though, of course, the individuals using that system are subject to data extraction through less 'technical' means
