  • How would they be made secure against faking?

    If the cryptographic key itself was extractable, it’d be easy to sign fake images with just a bit of custom software.

    If it isn’t, there’s still workarounds. Buy a professional photography camera, disassemble it, extract the chip that does the signature, feed it fake GPS and image data, and you have a modified image signed as legit. A country’s intelligence agency could easily do that.

    Even if the camera was made completely unmodifiable, you could put it in a Faraday cage, feed it a spoofed GPS signal for fake date/time/location data, and take a picture of a high resolution screen showing your photoshopped image.

    Building a system where end users are told “this image is cryptographically confirmed to be legit” just makes it easier to convince users that your fake images are legit.
