Right up until this becomes part of the adversarial side of the deepfake model. Detection is never going to be perfect, but I suppose it raises the cost to entry.
- mensetmanusman 6y agoExactly, this was new until the moment it was publicized :) Adding a bit of human-pulse oscillation to the color bitmap is likely trivial. There is no way to solve deepfake entirely beyond cryptographic signing. Apple should obviously implement this on iOS at least.
- AnthonyMouse 6y agoCryptographic signing is itself almost totally useless, and possibly worse than useless if people trust it when they shouldn't, because the signing keys by definition have to be in the device. Then you have to keep every model of every device secure against key extraction, which, let's face it, isn't happening; or the attacker will be able to sign their fake with the keys from whichever device has a vulnerability. And the vulnerability itself need not even be published.
- mensetmanusman 6y agoiPhones already have a UID architecture that I’m guessing could be used in conjunction with the iCloud architecture to at least provide a ‘this video/image wasn’t edited’ type of signing (with enough effort). This would probably prevent some classes of data manipulation for legibility/bandwidth reasons, which may make it too cumbersome...
