videos need to be cryptographically signed and able to be verified. all news outlets should do this.
agreed. having a cryptography mark on the file and relying on chain of trust is the way.
The NFTs tried to solve this problem already and it didn't work. You can change the hash/sig of a video file by just changing one pixel on one frame, meaning you just tricked the computer, not the people who use it.
That’s not really feasible without phones doing this automatically.
Even then didn’t the first Trump admin already argue iPhone video can’t be trusted because it’s modified with AI filters?
