I don't think this would accomplish anything. For one thing, quite a bit of misinformation these days comes from official government sources that can just compel the manufacturers to turn over authentic signing keys. Remember that Trump just posted an AI-generated video of himself shilling medbeds; when it was pointed out as AI-generated, he deleted it. If Truth Social checked the cryptographic signature, he'd order his staff to sign it. They wouldn't dare say no.
The next flaw is that cameras are happy to record screens playing AI-generated videos and mark them as authentic. Perhaps you can tell today because the screen pixels aren't perfectly 1:1 mapped to the image sensor pixels, but as soon as elections depend on being able to do that, those screens will exist.
People are saying to add LIDAR to prevent this "record the screen" hack, but a mirror over the LIDAR sensor and me sitting at a desk motionless looks to LIDAR exactly like the world leader I'm deepfaking sitting motionless at a desk. People are not using AI to generate amazing action shots.
At the end of the day, people will have to take some personal responsibility. Migrants probably aren't killing and eating pets. Pets taste terrible and grocery stores that you can just walk into and steal whatever you want exist. There isn't a bed that can cure any disease. If someone says they do, even a world leader, test them out on something non-critical. Break off a fingernail and see if the magic bed can regrow it overnight. If not, maybe stick to traditional cancer treatments until there is some clearer evidence.
It’s already possible. See the Stagecraft studio they built for the production of TV series The Mandalorian.
> shooting the series on a stage surrounded by massive LED walls displaying dynamic digital sets, with the ability to react to and manipulate this digital content in real time during live production
> The StageCraft process involves shooting live-action actors and sets surrounded by large, very high-definition LED video walls. These walls display computer-generated imagery backdrops, once traditionally composited primarily in post-production after shooting with chroma key screens. These facilities are known as "volumes". When shooting, the production team is able to realign the background instantly based on moving camera positions. The entire CGI background can be manipulated in real-time.
