    That simply won’t work, since you could just use a tool to recreate a Ai image 1:1, or extract the signing code and sign whatever you want.

      There are ways to secure signatures to be a problem to recreate, not to mention how the signature can be unique to every piece of media made, meaning a fake can’t be created reliably.

        How are you gonna prevent recreating a Ai image pixel by pixel or just importing a Ai image/taking a photo of one.

          Importing and screen capping software can also have the certificate software on and sign it with the metadata of the original file they’re copying, taking a picture of the screen with a separate device or pixel by pixel recreations could in theory get around it, but in practice, people will see at best a camera image being presented as a photoshopped or paintmade image, and at worst, some loser pointing their phone at their laptop to try and pass off something dishonestly. Pixel by pixel recreations, again, software can be given the metadata stamp, and if sites refuse to accept non stamped content, going pixel by pixel on unvetted software will just leave you with a neat png file for your trouble, and doing it manually, yeah if someone’s going through and hand placing squares just to slip a single deep fake picture through, that person’s a state actor and that’s a whole other can of worms.

          ETA: you can also sign the pixel art creation as pixel art based on it being a creation of squares, so that would tip people off in the signature notes of a post.

      The opposite way could work, though. A label that guarantees the image isn’t [created with AI / digitally edited in specific areas / overall digitally adjusted / edited at all]. I wonder if that’s cryptographically viable? Of course it would have to start at the camera itself to work properly.
