Riffing on your thoughts:
Killer blockchain app: Couldn't we just use blockchain to protect against video deepfakes? Hash every frame as the video is recording, then create an immutable ledger of frames. All "official" videos must be able to be verified with said ledger, and the ledger itself can only be verified with vendor-specific key licensed by a central authority. Perhaps two -- say, Apple has one for iPhone and they must verify as well.
This could certainly be the billion dollar opportunity blockchain fanatics have been looking for.
- chha 7y agoHow would this prevent anything? A deepfake is essentially video which has been edited. Most newsstories have also been edited, either by processing the sound, video or adding fx and graphics. How would you verify these edits against the ledger, and how would they differ from a deepfake?
- lifeisstillgood 7y agoI'm not sure about the blockchain part but I would suggest that we are just trying to prove that there exists raw footage (is an hours interview from which the one minute segment was edited) and that footage was shot on a unique identifiable camera, whose history can be traced. If the video of politician X making unguarded remarks comes from a camera owned by CNN for the past two years it is a different level of trust than it coming from one bought last week with a credit card in the name of politicians opponents new intern.
