Until someone figures out how to crack it real soon now.

It isn’t a new difficult-to-crack algorithm but a way of hiding information.

Can you find it?

Too late...

OK, so they can hide hidden data or compressed images inside an existing image. HOW CONVENIENT! Post an image on a conservative website, and everyone who visits the site has that image in their web cache. THEN, you raid the side, get a list of the visitors, and raid all of them for having “bad pictures of kids” on their computer. DESPITE THE FACT THAT THEY DIDN’T KNOWINGLY DOWNLOAD IT.

Might seem a bit far-fetched, but I wouldn’t put it past them to try it.

“In particular, the ability to send perfectly secure information may empower vulnerable groups, such as dissidents, investigative journalists, and humanitarian aid workers.”

And fans of child pornography.

"X- Steganography!"

A long time ago I heard it posited that one possible answer to Fermi’s paradox (”If aliens are out there, why haven’t we heard from them?”) is that they have perfected the ability to conceal their communications, so we can’t detect them. If we could find the signals containing their communications, we couldn’t get anything from the signal.

Nice 3-D but I cant figure out what it is supposed to be.

What? You don’t see Brandon falling on the AF1 stairs?

I sure do like your tagline...

conceals sensitive information so effectively that it is impossible to detect that anything has been hidden

Steganography isn't new and Al Queda guys were using these techniques to coordinate amongst themselves using messages hidden in pictures on message boards back in the 2000s. I was playing around with it in the '90s and it's older than that.

If someone wanted to use it to entrap us all they would make it uncrackable. Hypothesis: if you turn someone in for encrypted kiddie porn but you are the only person in the world with the key to break the encryption you might just become a suspect.

"If someone wanted to use it to entrap us all they would make it uncrackable."

If someone wanted to use it to entrap us all they would NOT make it uncrackable.

My posit on why we don’t hear from aliens is that any technology that can communicate across the vast distances of space is not going to be radio.

Whatever technology the aliens have it is to radio what radio was to semaphore flags.
