For editing it does not matter if you just remove or move frames. Video is just a series frames and each of them are signed, each frame can be validated if the content is unmodified. If the same root key is used for another stream, then frames can be combined easily. I don't know audio well enough how it happens there. But potentially it can be signed in chunks as well. Of course, one needs to consider risks if editi…

You do get into issues because video files aren't just raw frames and haven't been for ages. Plus any changes on top of the video wouldn't just pass the frames through beyond the fact that current video encoding would reencode the embedded video when the larger video it was embedded in was exported. You'd have to add support for seamless passthrough of the original frames so the signatures could be validated plus som…

> video files aren't just raw frames and haven't been for ages.

Does that really matter? You could sign keyframes, and then also sign the differences frame by frame til you get to the next keyframe.

We got lazy with the internet age. We’re going to have to go back to basic principles again. That means if you didn’t see it with your own eyes, it’s not real. If someone didn’t tell you in person, then they didn’t tell you. Maybe this won’t be a bad thing after all.

It might bring down all the bridges the internet helped build. Also, it will make the world more centralized, having to trust more on big names and institutions. As a libertarian, this is the opposite direction I’d like the world to go in.

We need to start trusting people we know again. Not institutions or celebrities on pedestals. We need to trust our family and friends and community again.

A recently announced breach at Retool[0] involved the use of a deepfake version of an IT employee's voice for social engineering. [0] https://news.ycombinator.com/item?id=37500895

"My voice is my password"

Is that a reference to the game Uplink?

There are no deepfake threats. Deepfakes is just the hype word for digitally altering photos/videos. In the past doing this well was restricted to governments, large corporations, large institutions. And they did it regularly. Now individual human people can do it themselves. That's good. That's not bad in any form or manner.

The difference is that rather than altered, they’re generated. It’s a new seeming-photograph that can’t be discovered as an alteration by checking against other photos to play “spot the difference”. Nobody really had this capability before.

>Nobody really had this capability before.

I find your distinction between altering and creating to be ... a sidetrack. But okay, let's pretend I said "Deepfakes is just the hype word for digitally altering or creating photos/videos".

Large institutions/etc have definitely been able to create novel "photos" from scratch for a long time now. It was just a lot of work, which is why it was restricted to large groups of people with lots of capital. Now even individuals can do it. And that's good. The idea that prior to deepfakes that photos could not be created is not supported by my lived experience since the 1980s. Just look at any hollywood movie.

Reliably left wing? Yes. Reliably truthful? No.

Please link me a single story you think NPR was untruthful about.

Or are there groups that upvote/downvote content to groom a certain narrative?

There are not many sites around that don’t have this problem.

I wonder why that is.

It might be the reference to the movie Sneakers. The quote from Sneakers is: "My voice is my passport. Verify me."

…what the camera saw. Cameras can record screens. Perhaps adding a signed channel for depth and/or non-visible light would be the next step.

Yes but the idea is that you trust the camera which unique and works as a physical private key.

> Yes but the idea is that you trust the camera which unique and works as a physical private key.

You're pushing a (bad) technical solution to a social problem.

Cameras that cryptographically sign their output will not solve anything. The idea has more flaws than it's possible to list, but here's a big one: do you really think a technological gimmick like that would stand up to a nation state? Do you really think the CIA, NSA, FSB, Chinese Ministry of State Security, etc. will not be able to sign whatever the hell image they want with a camera's signature?

to be fair, that article is about PRI, not NPR. They are not related.
