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...

Yeah. It's still going to be a barrier for some people but I'm guessing most could get comfortable with it if they were forced to. But getting my dad to do anything that isn't a voice call is pretty much pulling teeth. (Except for using Amazon. I think a lot of things are more don't want to than can't.))

Long term, the only robust way to solve this is going to involve a remote attestation chain i.e. video that's being signed by the web cam as it's produced, and then transformed/recompressed inside e.g. SGX enclaves or an SEV protected virtual machine that's sending an RA to the other side. Although hard to set up (you need a lot of people to cooperate and CPU vendors have to bring these features back to consumer hard…

The only solution will be in person meetings, as it has always been. Faking audio has been around a really long time. If you needed to be absolutely sure the person you're talking to is legit, you met them in person (mission impossible style disguises not withstanding).

Nothing has really changed with deepfake, other than the fact that for a brief period we could be sure the person we were having a video chat with was legit because the tech didn't exist to fake it.

I wonder how good the deepfake would be for things it didn't have training data on. For example, making an extreme grimace. Or have the caller insert a ping pong ball in his cheek to continue, or pull his face with his fingers. One thing I notice with colorized movies is the color of the actor's teeth tends to flicker between grey and ivory. I wonder if there are similar artifacts with deep fakes.

Please drink a verification can to continue, caller.

A can of Ubik please

Source: 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.

Yes I believe this sideways turning thing is mandatory when doing online identifications

I'd trust the data with a (real, not online) bank more than most other companies like Google. I'd be more worried about people hacking into networked security camera DVRs at stores and cafes and extracting image data from there. Multiple angles. Movement. Some are very high resolution these days. Sometimes they're mounted right on the POS, in your face. Sometimes they're actually in the top bezel of the beverage cool…

> Banks are the hardest way to get this data, not the easiest one. Is this statement based on data or a hunch? A quick google turns up a lot of bank data breaches.

A quick google turns up a lot of bank data breaches.

Because banks have to report data breaches. Do you think every neighborhood Gas-N-Blow is publicizing, or even knows, that it's been hacked?
