My Samsung phone has a feature that requires you to blink in order to unlock the phone to ensure that you're not a still photo.

Of course, I don't actually use it because the face recognition is so bad, and nonexistent in the dark.




Apparently that can be defeated with Photoshop.


Or maybe a animated GIF image.


Animated gifs would today work. What if the camera focused on something behind you first and then the face? Would that bypass a 2D method?


On a camera with effectively infinite depth of field? Probably not.


Couldn't the camera even just focus on a face and then the neck as a point of depth? Honestly, all of these quick-check systems have countless flaws.

I'm ready to have a chip in my arm now.


The point is they're both in focus. The camera (lens) isn't able to focus on the face and not the neck.
