I've been thinking about a future where deepfakes/AI are more everyday (which is soon).

I can imagine Apple doing some kind of hardware-level signing of camera and video data, so that any image shot by an iPhone/iPad would have a signature declaring that is was not edited by the user in any way. Details on whether RAW or any kind of auto-cleanup could be included.

In other words, a chain-of-custody kind of thing so that images can be asserted as real vs. created by a computer.

Depending on how such a system would be implemented, this would require "real Apple hardware" from the ground up.

This exists, and is why the (Canon?) cameras used by police departments at crime scenes are so expensive.

And "Real Apple Hardware" supporting "Real Apple ID" on every device in the network.

Cryptographic signatures can be decoded by anything which has the public key, that's not how this would work at all.

Cryptographic signatures are _meant_ to be decoded and verified.

If you want to take a signature you need to extract a secret key from an iPhone in this scenario, which would be probably stored in the secure enclave.

That's how asymmetric cryptography works.
