I'm wondering if all agencies are trying to capture as many pics of high officials of other countries to make the best training set.
Then they can use it during war.

Re: To uncover a deepfake video call, ask the caller to turn sideways
#82Probably a more robust test would be asking the caller to run their hand through their hair a few times. Maybe you could pre-render a few samples, but it would be trivial to request the person pass their hands through their hair in a specific way, or simply do it again after their hair is already messed up a bit from the first time. It could still be defeated by the caller having the same hair style (or wearing a goo…
in my career i've personally worked with no less than half a dozen bald coworkers.
i do think this is a good idea but won't work for everyone

Would you please stop posting unsubstantive and/or flamebait comments to HN? You've been doing it repeatedly, it's against the site guidelines, we end up banning such accounts, and we've had to warn you more than once before.
If you'd please review https://news.ycombinator.com/newsguidelines.html and stick to the rules when posting here, we'd appreciate it.
Note this one, just to pick one example:
"Eschew flamebait. Avoid unrelated controversies and generic tangents."
That's one of the most important rules for avoiding what turns internet threads dumb and nasty.

#84Perhaps could ask the caller to perform some other interaction that would be difficult to fake, like drinking a can of Mountain Dew. Maybe make them sing a jingle and do a dance...

in the UK this is already relatively common for online banking. I asked my bank to raise my daily transfer limit the other day for a property purchase and part of the process was recording a video of myself in their app.
And, of course, as barriers are raised it makes it very difficult for some portion of the population (and less convenient for everyone else). I have to change addresses for an older person at a couple of banks and I'm sure it's going to be a nightmare.
That being said, if instead of "use our custom app you've never seen to record a video" it's "just talk to a person with some standard video chat" then maybe it makes things a whole lot easier? But I don't see that being how it's implemented these days...
Re: To uncover a deepfake video call, ask the caller to turn sideways
#86Serendipitously over the weekend I was thinking about a future where for key sensitive data access (e.g. production main) you may need to have a quick 5 minute call (4th factor, "3D verification") where you would be asked to turn on your camera and be asked to answer some simple question and in different positions... Main thinking was how out of control it would get, it would probably end up looking like anti-cheat s…
We have PK cryptography you know, yubikeys and such.
Yubikeys can be stolen... I take it from the GP's description the access is sensitive enough to require more assurance than that.

#87Source: I work in the field. This is a current limitation, and an artifact of the data+method but not something that should be relied upon. If we do some adversary modelling, we can find two ways to work around this: 1) actively generate and search for such data; perhaps expensive for small actors but not well equipped malicious ones. 2) wait for deep learning to catch up, e.g. by extending NERFs (neural radiance fie…
Last time I applied for a credit card online, they asked me to take a video of myself and turn my head from side to side.

What if it's your CEO? Or someone from the bank? Or a college professor? Or a political prisoner?
I suppose the same way people used to deal with getting a letter from someone.
This is pretty funny. We're going to run the entire gamut of different verification technologies for them all to become compromised, forcing us to return to in-person transactions for everything.
Time to start investing in closed bank branches.

The two symbols we need you to hold are a loaf of BREAD and a FISH (the name of our church). This proves that the person in the photograph is genuine.
