Nikon’s been offering chip-based video crypto for years, it’s just not popular in consumer-grade hardware yet. If it was, we’d all be up in arms about our devices having a unique fingerprint in every photo (or video) that could be used to track us.

>If you wanted to do the cheap version of this you could probably set up a screen with proper lighting such that it'd line up well enough that screen and sensor pixels matched closely making it near if not completely impossible to tell a screen was involved.
You could make things more difficult by using multiple cameras (and perhaps some other sensors) to detect a 3D scene rather than just a 2D representation, but I agree that it's all ultimately fakeable.

Worse, such a signature on a fake video may give people false confidence in it being real, when really it still needs scrutiny especially if a possible state level or dedicated attacker is involved.
