We've been told that the antidote to deep fakes is supply chain security. It's troubling to hear that supply chain security is already broken and by fairly unsophisticated attackers from the sounds of it.
I would not use deep fakes to refer to counterfeit goods. Deep fakes refers only to artificially generated videos of a real person (usually face, but it could include voice).
Deepfake (a portmanteau of "deep learning" and "fake"[1]) is a technique for human image synthesis based on artificial intelligence. It is used to combine and superimpose existing images and videos onto source images or videos using a machine learning technique known as generative adversarial network.[2] The phrase "deepfake" was coined in 2017.
Because of these capabilities, deepfakes have been used to create fake celebrity pornographic videos or revenge porn.[3] Deepfakes can also be used to create fake news and malicious hoaxes.[4][5]
I didn't read the parent post as using it that way - I believe they're saying that any claim that "supply chain security" (of videos) will combat deep fakes* isn't necessarily a credible model of security considering that the "real" supply chain (of physical goods) isn't apparently particularly secure.
I don't think I actually agree, however. Things like hashing and cryptography make me inclined to believe a digital 'chain of custody' is easier to prove and validate than a physical one.
( *I'd never heard this before, but it's an interesting claim )
