Well it looks like there might be 2 competing systems for security/unlocking. Facial recognition is getting very sophisticated nows and maybe the days of holding up a photo of a face won't work anymore. Fingerprint reading is coming along with Iphone purchasing Authentic. Whatever system is implemented, you will still have to wake the phone up first, because of the battery drain if it is just waiting.

I just hope whatever systems are put in, they work quickly. 1-2 seconds would be okay. 8-10 seconds would not.

In my opinion, in the future, we could expect both, but while I trust in the fingerprint reader as much as in a password, I don't feel facial recognition very secure.

My understanding is that facial recognition is very good on the nexus devices now since 4.2.2. No picture can unlock it and it's very fast. I've only tried it a few times when I had my nexus 4 and remember it being pretty impressive.

^ facial recognition works as long as your face remains the same.

What if you grow a beard? Will it still work?

Fingerprint scanning on the other hand will always work, and so will a retinal scan.

The picture blocking is something you have to turn on and still not the best.

By turning it on what it is looking for is things like the eye blinking.

It depends on the beard. Really what it is doing is taking several measurements and looking at ratios. Like distance between the eyes compared to width of nose. cheek bone measurements. lip sizes and has ratios that it should be expecting for all that.

The features it looking for things like beards do not really changes it to much.

Does aging change any of those ratios?

I was looking at this the other day on my n4, but it tells you "someone who looks similar could unlock it."

I don't think face recognition is supposed to be super secure. It's just a deterrent from those nearby getting on your phone if you leave it laying somewhere. I think face recognition with a high enough security level to be considered secure is going to be to slow.

Finger print isn't that secure either if someone is willing to get your finger prints off of something. Don't confuse the police using finger prints to see who is who as meaning its difficult to falsify because its not.

I think head to head face recognition with a life check is more secure then a fingerprint but will be too slow of a method for unlocking a phone 100 times a day.

Most of the time, locks are to keep "honest" people honest. A true thief will just smash the window of a "locked" car to grab whatever is on the back seat.

But in a smartphone we are generally guarding our personal information. Who wants that? A thief? Possibly but unlikely. Friends and family? Possibly out of curiosity. Police? If so you have other things to worry about.

That said I would like a fingerprint reader for the convenience aspect. Facial recognition is cool and all that. But it doesn't work in the dark.

Facial recognition is pretty gimmicky. I can still unlock with picture on my HTC One probably because of 4.1.2. And blink check takes too long to use it day to day.
