"profile view challenge" coming in 3, 2, 1 ...

"Hey! To make sure you stay secure, we require a short video. Please look straight into the camera and tap the screen." "You look great! We just need you to blink 5 times, and you're almost done!"

Just turn your head to the right like displayed above, and we can continue." "You've almost g…

Absurd requests will increase in absurdity as long as there is not significant push back.

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.

This sounds like a great way to get sufficient images/video of you to create a deepfake that could pass this test. Hmmm...

And now that scan could eventually end up out there someplace.

Agreed. Now they have the data to deep fake you turning your head.

I hope they delete the data immediately after use.

Slightly more robust method...

Ask the caller to move out of the frame and then back in again.

You will see a noticable 'step' as the face that is partially in the frame suddenly gets detected as a face and the deepfake is applied.

The only way around this is to crop the input video quite heavily - by at least one face diameter, which is a lot if the user is near the camera.

Interesting to bump in to somebody that works in this field.

What do you do in this field?

What's the direction of travel on it?

What makes it worth pursuing at a commercial level? In other words - how is this tech going to be abused/monetized?

May I ask what card/Institution? This would be an immediate no for me.

Tangentially related but a simple way to bust a chatbot is to ask “What is larger, the Eiffel Tower or a shoe box?”

Here's what Meta's blenderbot replied with: "The Tokyo tower is taller than the eiffel tower. Interesting facts like that interest me. Do you know about it?"

Side thought: I really enjoy how similar some of the suggestions (in TFA and comments) resemble reality checks for lucid dreaming. In general Observing something and asking oneself "is this really how reality behaves?" Which is such an interesting question itself to question the nature of reality beyond our own initial perceptions.
