Difficult and also solves nothing, since you can just point the camera at a screen.

- fightfake-ai 22d agoThere is active research addressing this problem, for example https://www.usenix.org/system/files/usenixsecurity25-park.pdf https://www.usenix.org/system/files/usenixsecurity25-park.pd... But yeah, difficult too :)
- thaumasiotes 22d agoHave you ever tried pointing a camera at a screen? The screen is doing all kinds of crazy things that are not apparent to your eyes, but that show up clearly on camera.
- blincoln 22d agoSome screens are like that, but it's not an inherent property of all visual displays. For example, you'll see a sort of barber-pole effect when pointing a video camera at a raster-scan digital display whose refresh rate isn't synced to the camera's frame rate. To avoid that, sync them, or maybe use a colour e-ink display. Alternatively, print a high-resolution version with a decent photograph printer and take a picture of the print with the C2PA camera.
