Leica M11 signs each photo. "Content Authority Initiative" https://leica-camera.com/en-US/news/partnership-greater-trus...

Cute hack showing that its kinda useless unless the user-facing UX does a better job of actually knowing whether the certificate represents the manufacturer of the sensor (dude just uses a self signed cert with "Leica Camera AG" as the name. Clearly cryptography literacy is lagging behind... https://hackaday.com/2023/11/30/falsified-photos-fooling-ado...



Even if the certs were properly cryptographically vetted, you could just point the camera at a high-enough resolution screen displaying false content.
