Reply to comment by czl 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
Wouldn’t it be even safer to encrypt the orinal anyway and then obfuscate it with stengraphy?

But if you encrypt information everyone knows there's information to be uncovered. Not every image you come across on the internet has hidden messages.

Encrypt a red herring or low value info and inside that put the sten?

That’s usually what you’d do. Typically steganography isn’t your only form of security. You’d encrypt it first, then encode it. And even if you can detect that there is a hidden message encoded in some file, that doesn’t mean you actually know how to extract it even if it’s not encrypted.
The steganography is really just there to try and avoid having people know you have something worth encrypting so that they aren’t trying to figure out what it is in the first place.

Originals are proof stenography was used. You destroy those since they are not needed for anything after you send the altered media.

You don't need to keep the original at all. Just delete it. The version with the hidden message should be the only version anyone but you ever sees.
