They mention their own captcha system but don't really reference it anywhere as far as I can tell. I'd guess it'd be based on something like ARC (Abstract Reasoning Corpus), instead of object recognition which already have decent methods of solving if you can get enough data.

couldn't find anything...

Can someone please explain to me why smart people keep saying that we’ll just build software to detect deepfakes? When AlphaZero plays against itself it just gets better. Once that spread is so narrow, every deviation is in the range of possible error. And it can’t explain WHY a certain move is better or why the picture is a squirrel. And sometimes it can be wrong, but only on hilarious edge cases, in the rest we jus…

security by obscurity - The companies detecting deepfakes will certainly not publish their methods/networks.

And what about universities?

There are plenty of publicly published papers detailing detection of deep fakes.

Step 1: Use Captcha to get free AI training data. Step 2: Sell improved AI. Step 3: Add edge cases to the Captcha that your AI can't handle yet. Go to step 1.

Up until the last decades, photography was an art, and photos were generally manipulated, sometimes heavily , sometimes to remove people etc. This is not new, human societies have survived without video evidence since forever

> photography was an art, and photos were generally manipulated, sometimes heavily , sometimes to remove people etc.

Except this was time consuming and couldn't be done automatically in an undetectable way.

> human societies have survived without video evidence since forever

Stupid argument, we've also survived war since forever, except now a war between nuclear powers would be devastating in a way war historically wasn't. It will absolutely not be the same as it was before photos and videos.

I did collect the images from the puzzles, here is a few: https://drive.google.com/open?id=18b0HxyOsLP6AZMpF1-DNITrGvF...

Woah, I never seen something like this done with bash and command line utilities. Thanks for sharing, made me find xdotool which is exactly what I neede to replace SikuliX. I can't comment on the project since I didn't test it but wow, only this example https://bitbucket.org/Pirates-of-Silicon-Hills/voightkampff/... made me think why didn't OP use a scripting language and went with Bash? (Python?) Don't get me wrong,…

Sikuli has the benefit of being fairly cross-platform, so scripts written for X will also work in Windows and in theory other more esoteric window manager environments. It also has the ability to identify visual cues, which this doesn't seem to do.

Sikuli is not fast enough. I have know about it since it was developed at MIT because I was there in 2010

At some point Captcha's will be easier to solve with software than by people. Hopefully by then we can retire them completely. The onus for proving that a visitor is not a bot should be on the server side, not on the humans.

Server should never trust client input How would it make that determination?

That's not my problem. As a user I should not be inconvenienced for a problem caused by someone else. The offending party should pay the price.

And we see what happens when we do have video evidence because everyone has a camera in their pocket. For decades law enforcement version of events were taken as gospel. Now we have evidence that they do lie.
