npub19qm2trjs3p32nwqwry4ufxl4fk9q4utkq53ywueg0yk8cvggra5s79sn8k (npub19qm…sn8k) it depends on how this "signature" is implemented.
We already have image metadata stored in most of JPEG images - it's called EXIF headers. Photoshop and GIMP already know how to deal with them (they may add their own headers on save but not touch existing ones). If such signature is just another EXIF headers, I don't see how an AI algorithm couldn't simply mimic the header (you don't even need AI for that).
Unless the header payload is encrypted with a private key that only the manufacturer owns, of course - but then the question becomes "how do you efficiently distribute the public key to everyone to decrypt/validate the header".
