Interesting idea and I think Nikon did with high end(?) cameras a number of years ago. Nikon tried this a number of years ago, and I am not sure if they ever managed to stop hardware hackers from extracting their private keys, here are some examples: https://petapixel.com/2011/04/28/nikon-image-authentication-system-cracked-just-months-after-canons/?utm_source=chatgpt.com https://petapixel.com/2011/04/28/nikon-image-authentication-... On a second reading it seems that Canon keys were leaked even earlier.
