Take a new picture, encode info, destroy original picture so no one can compare it.

Or if the process requires comparison of the original you could simply use wily different methods of sending the original and the doctored image. Send both via sneaker net and thumb drives with self destruct buttons.

But the main one being don’t let the same people see the good and doctored image for comparison.

Well, allegedly whatever type of steganography the article about doesn’t, but they don’t go into detail so I have my doubts.

The extent of my experience with steganography was a grad course a few years back with a professor who was a big name in the field. So I’m not an expert or anything, but I am somewhat familiar with this. And in my experience the answer is no. It’s an arms race. Someone comes up with a way to hide data, someone else comes up with a way to find it, so someone else comes up with a new way to hide it, so someone comes up with a new way to find it, etc. That’s not to say it’s perfectly accurate and that you can always tell with 100% certainty if a file has data encoded in it, but every method I’ve seen creates some artifact that is generally detectable with with a high degree of accuracy using the right kind of statistical analysis.

impossible. perfectly secure.

LMAO. People who knows nothing about how security works.

Humans have never created anything that's "perfectly secure". We might someday (probably not), but haven't yet.

Well, Pegasus specifically had been seemingly mostly used to target high-profile, valuable individuals:

Diplomats, activists, etc

Modern day spy stuff, frankly

I'm not buying.

This just seems like a gov't honey pot to me. Of course, I could be completely wrong and maybe they did discover "perfectly secure" communication algo, but I doubt it.

Stego is usefull in a very different way from crypto. With crypto shure i might not know what you are sending between yourselves, but i can know that you are sending stuff. Thus if i catch one of you doing a crime for example, i will be very very interested in investigating your crypto communication buddies, even tho i do not know the messages themselves. Stego aims to fix this by hiding the fact you ever comunicated in the first place. This type of security is ONLY achievable by obscurity.

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

Interesting. But it sounds like you're saying that the vulnerability is limited to some forms. Are there forms of steganography which lack that vulnerability?

How's this gonna sit with EARN IT in america? EARN IT bill passed in 2022 and puts companies on the hook for crimes committed against children, and specifically seemed to have been made with cryptographic messages in mind.
