The legal issue is that they used the authority of the Whitehouse to do a "comply or there will be consequences". We've all sat through various crappy powerpoints on ethics. That is plain and simple coercion. That's a first amendment issue and prohibited.

I haven't looked into this issue in detail and was surprised to see such a brazen threat so I wanted to find information on your quote "comply or there will be consequences". I'm not able to see that in the context of white house or twitter. I haven't found anything close to it yet. Could you point me to that information?

I'm old enough to remember back in 2005 when terrorist in Iraq claimed to be holding a US soldier hostage, and it turned out the whole thing was staged using photos of a doll: Original story: https://www.nytimes.com/2005/02/02/world/africa/rebels-say-t... Confirmation of hoax: https://www.nbcnews.com/id/wbna6894934 It's pretty easy to see that the photo is a hoax, but many news outlets didn't notice and ran the story…

I always have to think of the Wu Ming Foundation/former Luther Blisset collective and their fake news/LARPing missions[1] that showed how easy it was to fool major news outlets back in the 90s. Too bad that now those same techniques have been weaponized with great success. 1. https://en.wikipedia.org/wiki/Luther_Blissett_(pseudonym)#Li...

Loved "Altai" and "Q", the historical fiction they produced (under that pseudonym and "Wu Ming")!

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…

Let's say that camera records in 60fps. Maybe all the data on all the channels can be recorded in chunks of 1/60s and signed separated. Then camera combines it as whole playable video, but then there is a separate metadata for each time/byte offset which have been signed. At the beginning, camera manufacturers might need to provide their own editors, to make editing possible. How much we can trust the camera holders,…

Intraframe compression where each frame is individually compressed is barely used any more outside of movies and other professional nonsteamed production because it barely compresses the resulting video. Most streaming and consumer video cameras use interframe compression where you get a full frame every few frames and the rest are moving pieces of that around. This video by Captain Disillusion [0] goes over it much better than I can and any time the video is edited it goes through that process again of creating I-frames P-frames and whatever new homunculus frames are invented to further compress video while maintaining quality.

If you just cut away to the original clip and didn't have any modifications like motion graphics over the top of it you could in theory pass through the original video with the same compression and signing without too much drama but any modifications over that or presenting it as picture in picture would be a big difference as now you need to have both the original frames with the added graphics on top.

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.

One minor hiccup being that the allegedly coerced entities didn’t claim (and still haven’t claimed) to have been coerced.

perhaps because the threat of "comply or there will be consequences" worked.

Except most of the posts pointed out to places like Twitter stayed up with no moderation applied and the worst thing that's happened to Twitter recently is it's acquisition by Musk.

That is not really more likely. Most news outlets don't actually want to have a horrible reputation.

Yes and if other news outlets were already tricked, they could run an even better news story about that.

Interesting lecture on the connections between Q and Qanon by Wu Ming 1, also detailing some of their LARPing and hoaxing exploits: https://www.youtube.com/watch?v=VdcAT7pXYko

Really? How about not using unofficial channels for statements? I mean, what is new to this problem. Other than it is somewhat cheaper to pair the fake statement with the person responsible reading it out laud. Department press release -> Reuters -> News paper -> reader No signing required. The reader can verify the press release of he wants to.

It is different in my opinion. * Text: You have little (definitive) clue who wrote what. You essentially have to ask the (apparent) writer. * Photo: You used to have high confidence that a picture shows who appears to be shown. Not 100%, sure, but it's high. * Video & Audio: You used to have very high confidence that the video including its audio are genuine. It was very difficult to replace video and/or audio. Nowad…

This has long been a solved problem out in the real world.

Think back to the Nixon watergate scandal. When the reporters were going to press about that, they made damn sure it was 100% real first. By interviewing varying sources, human trust, etc.

All that really changes is they can't take video and audio evidence as fact anymore. So they have to, in essence, audit the video/audio trail, so they will want to talk to the person that filmed it, make sure the story holds up, etc.

Some technology changes can help with authenticity here, but it's not really a technical problem, it's a human trust problem.

There will be learning curves and maybe one or two of the currently well known and trusted news sources totally burn their brand because they didn't do their homework. Nothing really new though.

NPR seems to be one of the most reliable sources in America.

Reliably left wing? Yes. Reliably truthful? No.

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