If you are trusting a camera to upload to a blockchain, the same can be simulated on a computer, given enough time.

The idea is to say “these images/sounds were recorded at this time by this device,” and to have that statement both registered publicly at the time of creation and backed by the reputation of the device maker. It’s acknowledging that using AI to catch AI fakes is a fool’s errand, and relies instead on the premise that hashing a raw data stream is much faster than producing a good fake, and that a secure device key is secure. You’d need both for it to work, otherwise you can generate a deepfake beforehand and get the device to sign a fake stream. That may be easier to do than I think; this is not my area of expertise.
