That's nice...the government will have access to this, and anything they have access to, they'll learn to break into. I'd be surprised if the CIA's "PRISM" can't intercept communications under this new protocol within the year.

What if they have a system which just runs an app that takes a picture with a phone and encodes the data in the least significant bits of the photo? If they can keep the LSB order random using an crytographically secure PRNG, it would be somewhat secure. The problem is, if an adversary believes a photo contains stego info, then it just becomes a crypto problem. Stego is just a form of security through obscurity, which generally isnt a good security policy.

Again!? 🤣 I give them 6months to a year before this is found to be a scam or used by criminals and the Feds requiring a backdoor that is then exploited by cyber criminals 🤣

> Cryptographic hashes are a perfect test for this type of communication - the hash of the original will never match that of the altered copy

You're assuming you can access the original.

Nobody but you has access to the original, so unless you can detect the steganography without the original it is "perfectly secure".

I didn't read anything on this, but I'm guessing the only real advance is that the encoding is not discernable from noise.

This is my general argument for the whole "ban tiktok" argument.

To think that it's just Tiktok doing this is ignorant.

We literally saw Facebook's affect on politics via Cambridge Analytica, and that was 100% data driven science. They literally manipulated the flow of information to particular types of people and fucked with their brains enough to sway their whole thought processes.

To think there is no one else in the world doing this is ridiculous.
