I was recently looking for designers for my company when I came across an interesting profile on Dribbble. I reached out and quickly scheduled a time when we could talk over zoom. At the meeting time, in comes this person who seems to have a strange-looking, silicone-like face. I was using my Zoom account (I rarely use other peoples zooms unless I trust them), to avoid situations like this. One thing I noticed is tha…

> Arguably, this approach could be extended to automated systems that ask the user to adopt various poses in order to authenticate their entry into banking and other security-critical systems.

This approach works until it doesn't. How long before deep fake can handle the 90 degree profile scenario? Not saying its not a valid approach but you'd have to consider the time it takes to implement these other checks and then the time we expect deep fakes to improve in this scenario

Is audio harder to fake than video? I was watching the Keanu one and wondered if it is harder to real time fake Keanu’s voice than his face?

No. Both face the same challenge - quality of data. The rest has already been solved.

Here we go again... there's a rule that describe this situation where a measuring matrix becomes the standard, the said matrix is no longer indicative.

But please, I don't want to be pointing to a random bus outside my window to prove that I'm not a robot/deepfake...

The degrade of news article quality > the degrade of fact-checking journalism scrutiny > the degrade of written article quality > people rather watch live stream event than reading > degrade of live stream event trustworthiness because of deepfake...

What's next? Heavily scrutinised journal articles which runs check on videos with anti-deepfake AI-based algorithm?

Oh wait we've just gone through the full cycle.

For what it's worth, it looks more like an aggressive filter rather than a deepfake.

Earlier quoted context omitted.

Yes, but one of the points of the article is a distinct lack of source material to train models on profile views

For people like Tom Cruise that shouldn’t be a problem.

> ...,we need to consider the high availability of data for notable Hollywood TV and movie actors. By itself, the TV show Seinfeld represents 66 hours of available footage, the majority featuring Jerry Seinfeld, with abundant profile footage on display due to the frequent multi-person conversations.

> Matt Damon’s current movie output alone, likewise, has a rough combined runtime of 144 hours, most of it available in high-definition.

> By contrast, how many profile shots do you have of yourself?

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…

“The Impossible Mission Force has the technical capabilities to copy anyone’s face and imitate their voice, so don’t base your secops around someone’s appearance.” … yes, because that worked well.

> … yes, because that worked well.

Just to be clear, Mission Impossible is not a documentary.
