    If this ever became widespread, people would game the "verified real" checkmark using the analog gap.

    1. Print AI photo 2. Point fancy expensive camera at printed photo 3. Take a "real" photo

    Then you'd see more sensors and even more expensive cameras. Then you'd see miniatured virtual-production volumes.

    So, this is not a solution. It's just an arms race disguised as one.

      Can you photograph a photo so it’s not really noticeable?

        Yes to arbitrarily good degree with hobby grade tooling. The previous gen photo tech (b&w negative film, colour negative film) used device called enlarger† which is pretty much taking a photo of a photo.

        I&#x27;ve been able to get some truly great digital copy of old analog printed photo using Google snapseed and a sub 1k€ smartphone and that was almost a decade ago, so I&#x27;m pretty sure anyone dedicated can.

      This would make deepfakes more expensive because you would have to tightly control the chroma and illuminance of the display.

        Something a calibration tool surely can do I assume.

          Fakes were always possible. Just labor intensive or costly.
