There's still pretty solid techniques for spotting photoshop fakes. Is this not likely to be the case for videos for a long time as well? Or does the machine learning element obviate that

Generative Adversarial methods make this difficult, because they already use "systems for spotting fakes" as part of the teaching process to make better fakes. As such, if there's an innovation in fake-spotting technology, it can be directly applied to improving fake quality.
-
Yep. But maybe human forensics pros will be able to do some things that the automated tools can't, for a little while longer.
-
Oh for sure. Most people can learn to spot GAN artifacts pretty quickly (traditional convnets seem to have trouble grokking geometry, which might be a max pooling artifact). Long term, though, the advantage lies with the generators.

Additional concern: the disintegration of trust in traditional media is now a central tribal signaling thing, so all of on the left are (to some extent) prepared to boil like frogs.
-
To clarify, I'm mostly concerned about *unintentional* dissemination of fakes. I'm pretty certain the media will be overconfident wrt its ability to identify them, even w/o using all available tools. A lionized press that's not well calibrated for this is going to be a disaster.

It's surprising to me how well timed the public adoption of verifiable blockchains useable for evidential integrity is.
-
(And yes, this is only useful for certain classes of proof, like "verifiable camera X signed that this happened at time Y with its private key.")
-
OK, so do you have ideas for who to ask for funding for our startup to develop this system and license it to high-end video-camera makers?
-
I’ll DM you!

The solution is that camera vendors start including chips that digitally sign the output images / video frames, and display applications need to verify those signatures, showing a big warning label for unsigned images.
-
There have been some attempts at signing cameras but they had security holes. So that needs to be done better, and the camera certificates used for signing must be signed by a CA that can sign a public revocation if such holes are found.

The credibility of audio is also nearing it's end.
-
Yup, I'm given to understand that Adobe is working on something like that. On the plus side, maybe I can eventually buy a synthesised voice pack that's based on James Earl Jones or Christopher Hitchens.
-
Bunch of companies are working on it. The Hitch voice pack sounds amazing, btw.
-
Wait, is there a demo of the Hitch voice pack out there? I'd love to hear it, if you know where it is.
-
Hahaha, no, I meant the idea for it sounds awesome. I wish it was out there...
-
I'd say it grows more likely with each year.
-
Only a matter of time. Can you imagine a program that would read ebooks to you in anyone's voice?
