Face Unlock becomes smarter in Jelly Bean: asks you to blink for the camera

Face Unlock becomes smarter in Jelly Bean: asks you to blink for the camera
Face Unlock was one of the coolest new features in Android 4.0 Ice Cream Sandwich, but while having your phone recognize your face sounds like a fun (it is) way to access your device, it definitely isn’t among the most secure ones. 

Face Unlock becomes smarter in Jelly Bean: asks you to blink for the camera
Why? Well, you can easily trick the phone into thinking it’s seeing your face when you’re actually showing it a picture of yourself. With Jelly Bean things have improved as Google has now added a feature it calls “Liveness check” that basically asks you to blink in a certain moment and only then unlocks the phone. Now, that’s something a photograph can’t do and definitely an elegant solution making it harder to crack the mechanism. 

Is it still possible to trick Face Unlock, though? Certainly. All it takes is a bit of tech savvy to craft an animation out of still photos with you with open and closed eyes, and then play it to your phone’s camera from another display. But still, that’s much harder than just showing a picture, isn’t it?

Anyway, we’d only use Face Unlock for the fun and coolness of it, not for real safety, and we’d advise you to do the same.

Then you don't have to use this feature. Freedom - you decide what to use, and what not. A radical concept these days of the iOS plague, I know.

I was actually impressed with face to unlock. It worked way better then I though it would. That said, I had to stop using it, I work outside and wear sunglasses all day.

Face unlock does not work well with sunglasses and I imagine it will not work at all now being it won't be able to see my eyes blinking.

they should instead have you rotate the phone around your head or something that requires 3d authentication. because its still pretty easy to bypass whether its animated digitally or whether i just take a pic and some construction paper. nevertheless it's still really cool!

i think i can see the new iphone ....
*NEW , iUnlockByFace!* ONLY on iphone lol
