I find it amusing that Congress has suddenly become so interested in the dangers of deep fakes. When they started going on and on about the dangers I thought “why is this dude so worried?”. Then of course the Epstein stuff becomes news[1] months later and the cynical part of me can’t help but think they’re looking for a defense if they ever partied at his island or ranch. 1. https://nypost.com/2019/11/18/jeffrey-epst…

Deepfakes are readily understandable as a problem for politicians. Politicians are experts in public messaging; this technology has the ability to alter previously-immutable messages.

We've had the ability to make convincing fake videos for a long time. There are whole industries devoted to the task.

I think the bigger problem is it provides deniability and removes accountability. The "I never said that" kind.

Could blockchain give us a secure audit trail for digital video clips?

The blockchain could provide a timestamp, but it's hard to see how that would help.

Every type of video authentication system I've ever heard proposed can be defeated by simply pointing a 'trusted' video camera at a screen playing a fake video.

kind of... you can create a hash of the video, and store the hash on a blockchain. Then when viewing the video in the future, you can check it's hash and compare it to the one stored on chain to be sure the video wasn't tampered with.

But then you need to establish that the hash was posted on the chain by a trusted source, too.

It still looks wrong. There's still some of the floating/stuck-on head feeling about it. Or is that just because we already know it's fake from the headline? (... and the way that the flag moves is totally wrong .../s).

Don't forget the other side of the coin:

The President really does give a speech or make a comment, but 50% of the electorate is sure it's a deepfake.

Of course not. There’s no plausible mechanism by which it could.

Deep fakes are yet another prime example of how the writing is on the wall (i.e. it's clear that this technology can/will be used for nefarious purposes - esp. by our enemies) and yet mitigations - through regulation and enhanced standards - won't be pursued until long after the horses have left the barn. I don't know how/what form this should take, but an older analogy might be how colour photocopier manufacturers i…

Sadly they do not really need deep fake technology to spread fake news

Make-A-Wish Foundation can really benefit from this technology by sending these "heartfelt" deepfake videos of famous celebrities and idols to dying kids, hoping to cheer them up. Is it an ethical thing to do? You be the judge!

This is fantastically evil. I think you win the dangerous idea of the day award. It reminds me of the market for answering machine messages, but here you will have a large catalog of celebrities and you can create a personalized video message of them talking about you or someone you know. A con artist could also buy that to pretend they know a certain person. So the website would work like this: you pick a celebrity,…

What if that's what the startup Cameo is actually offering? https://www.cameo.com/

I think this is a regional thing. I'm from a rural community in Canada, and of course we answer the phone. Just floors me to visit my mother-in-law in Texas; when we visited eight years ago, she'd answer the phone; now she doesn't answer her cell or her home phone unless it makes a distinctive ring. I'd hate to need to get ahold of her using someone else's phone.

Obviously I'm not your mother-in-law, but I also don't answer my phone unless it shows it's someone I know because 95% of calls I get are spam. However, I will check my voicemail. So far every legitimate caller has left one to my knowledge.

That is pretty strong selection bias however...

We’ve had photographic deep fakes for decades now. How does this fundamentally change anything more than Photoshop already did?

We've also had video since before convincing photo edits were available. So people learned that we shouldn't trust a photo of Martians, or a sound clip of the President confessing to murder, but should hold out for video. When footage of Rob Ford doing crack cocaine shows up, we believe it's real. And when an investigative reporter wants a verifiable record of something, they resort to a high-quality video. Even if v…

Firstly, Ford was already known for that behavior. The bar of legitimacy was low. The famous early nazi fakes; looping rows of tanks and troops to suggest more, was indeed effective, and nothing new. We have been in this space for nearly a century already.
