Steganography is a (fascinating) bitch. There are a lot of ways to hide a message in an image which is very resilient to manipulations like resizing, compression or even the loss of information by actually filming a screen versus taking a screen capture.
If you adjust your approach to not rely on a single picture to reliably convey a short message, but part it out over tens or hundreds of frames in a video, it’s basically impossible to make sure that the message was erased without knowing the algorithms used or rendering the video unwatchable.
It’s an awesome field and nothing new.
I’m a bit disappointed with the hypocrisy of some commenters here.
So many very questionable articles, posts and statements that can’t be verified regarding IDF crimes get treated as the absolute truth. Yet a statement regarding a fake story, verified by Hamas and Al Jazeera, gets reported and isn’t trustworthy, since it’s from an institution aligned with Israel?
Holy echo chamber, batman.
