Selfies reveal smartphone pin

If so, one's PIN would be revealed when the screen's image didn't get in the way.
This article (I tried to find a more informative one than this and failed--maybe I'll try to find the presentation itself) seems to imply that one could film at sufficiently-high resolution someone's face and eyes, and reveal what was on their phone screen. Interesting stuff. Like Starbug says, "Everything can be spoofed."
The order of the pin (4-6 characters on most phones?) would still need to be figured out. So it depends how many guesses the user enables. With 24 different permutations of 4 digits and iPhones having "wipe the phone after 10 failed attempts" option this would have a little under 50% success rate.
Which is still a huge improvement over "just guess" but hardly "we can pwn you from a photo every time" territory.

and I agree with this:

It sounds like neither of us is concerned about being pwned from this. But I take from this that given enough time, someone will find a way to get unintended-data-emission from people, and it'll be from an unexpected source.
