There is a simple technical fix for this.

Have the cameras sign each frame. Other than needing a new camera, don't see the issue here. Then you can deep fake all you want and it gets marked. No mark... Means it is highly suspect.

The tech already exists, and is even already implented in some cameras. It would be a software change to have my smartphone start doing this. One signature from the device and then my signature as the owner/operator.

1. What keys are the cameras using to sign each frame? Where are they stored? How are they accessed? How are they verified?

2. Hex editors let you manipulate the individual bits in a file. What keeps someone from editing the raw image file to remove the watermarks?

3. Why is no mark highly suspect, if the mark is a sign of a deepfake? That sounds backwards.

4. If the solution is as “simple” as you suggest, why isn’t it being used? Or do you honestly think you’ve thought of something no one else in the field ever has?

The camera has my camera signing key and the camera's signing key. Standard PKI stuff. Anything not signed by trusted keys is not able to be authenticated.

Why should you trust a pic/video with no signature and not a website?
