Yeah but does it actually work, though? There have been a lot of online tools claiming to be "AI detectors" and they all seem pretty unreliable. Can you talk us through what you look for, the most common failure modes and (at suitably high level) how you dealt with those?

Give it a try for yourself. It's free!

We have been working on this problem since 2020 and have created an trained an ensemble of AI detection models working together to tell you what is real and what is fake!

Proof of work is not needed, just a pool of time servers that you can make a quorum out of. We're working on exactly this on top of roughtime (https://roughtime.googlesource.com/roughtime) for a future version of QR Date (https://qrdate.org/)

Great discussions! Some thoughts:

First, there are multiple solutions to this problem, all need to be explored and many will have a part in the future. Bad actors will do everything they can to find a way around every solution.

Second, for the hashing approach, have a look at "Perceptual Hashing", it's a way to hash content like a an image, even if the resolution changes.

Where to store the hashes? A centralized server is probably fine, but there is always a risk of a bad actor exposing it somehow. A secure blockchain can work better. But if you go that route, might as well go with the most secure blockchain. POW is generally more secure than POS. And currently the most secure blockchain is Bitcoin. So one solution is to batch hashes together and write them with a Bitcoin transaction in some cadence.

This is definitely an interesting problem, and I can see a place for it.

I want to comment (in ignorance because I don't know the techniques you are using) that there is more to detecting fakes or "misinformation" than just the digital attributes of the data. Specifically, confirmation from multiple sources, reputation of sources, and above all, consistency with a world model of how people behave. For example, if there's a video of Biden backing Putin, you could dismiss it as fake regardless of video attributes.

I think (and have been criticized for saying, why I don't understand), that education and emphasizing critical thinking are the biggest counters to fakes, not learning to spot them in feature space. I believe that whatever you make, sanity checks need to be a part of it, and not just blind flagging of true / false based on the digital attributes.

Thanks!

Great points! This is a problem that must be tackled from multiple directions. Different tools that flag content and general education.

We plan to guide our users in this way, incorporating these different tools and providing general education.

This is super cool, you should chat with the folks in Estonia who had worked on developing Sentinel (https://thesentinel.ai/) which had a similar premise but ended up pivoting. I advised them for a bit, happy to chat too (email in bio).

Edit to include link to their website

asail77 · 3 years ago

Awesome! We will look them up! And happy to chat with you. You can also email us at ask@realitydefender.ai

Thank you!

That makes sense. But if signed AV takes off, the video someone else took of you and shared likely bears their seal. And audiences decide how much they trust that source – just like they look for a CNN / BBC / etc logo in the corner currently.

Great discussion. Many have asked the same questions.

We hope a standard will be created and used by all digital content creation tools. But this will take time. And even then, bad actors will not be deterred. They will always find ways to create fake content and pass it as authentic. We want to be there to fight them every step of the way!

We have solved this problem already for text with digital signatures. There might be a way to digitally sign speech in real-time and show the signature on a display device, which is captured on video. It could be just a smartphone app or a separate device. This way every video could be proven authentic, even if they originate from unofficial sources.
