One of the more frivolous features introduced into Android with Ice Cream Sandwich, was the Face Unlock. While it's always been something cool to show off against your iPhone toting friends, it's never really been overly useful, or secure. It's not the most reliable feature in the world, and it can be duped by a photograph, and generally makes unlocking your phone longer.
Enter Jelly Bean, and an improvement to Face Unlock. Pointed out in the Android Central Forums, by member Jays2Kings, within the security settings menu in Jelly Bean is a new option -- Liveness check.
So, this is supposed to get round the potential picture duping issue, by making it so Face Unlock will check for the person in front of it blinking. In other words, making sure you're alive. While it's good to see solutions for potential security risks, Jays2Kings also points out that it doesn't really pick up normal blinking too well. Seems that it works best when you have your eyes open really wide, and all it seems to do is to further slow down the process of unlocking your phone with Face Unlock
How about you guys? Anyone who's running one of the Jelly Bean ROM's already out there, and tried this out, shout out in the comments and let us know how it works for you.
