With your scheme you can't prove the timing of when the hash was made, nor who made the hash. At the very least the camera would have to include something that proves the time in the hash, and then sign the result with a private key that can't be extracted from the camera.
Trusted, cryptographic timestamps exist, and have for some time. NFTs don't add anything new.
Okay good. I thought it would, just didn't know any specifically. I wasn't trying to suggest a public blockchain would be the only solution or even the best of multiple solutions, only that they needed to consider more angles beyond just making a hash.
