Google says Face Unlock will not work with a picture

Do I have to smile? What if I'm just an angry person?

Google has being woking on this for quite some time ,how old is the Nokia feature ?

8. MichaelHeller posted on 20 Oct 2011, 12:31 4

I like to see real world usage rather than controlled demos anyway.

Yet...iphonearena already posted a "review" of ICS. Now we are forced to read about your "guess" as to how it operates. Surely you have hands on experience, right? No one with a shred of ethics would "review" an OS they had never used...would they?

Can't "review" an event you did not attend either ( how is parking in Hong Kong, Michael? )...but no one would ever be so small minded as to attempt that...right?

Your kind of a d**k

We actually haven't posted any "review" of ICS. We have only posted previews of features to expect.

I'd say a full video feed of an event gives enough to review. It seems you would agree since you've found enough about me to judge without having met me or had a conversation with me.

I have no intention of starting a fight, but I will certainly defend myself and this website from anyone slinging mud unjustly (and hypocritically in this case).

I'm guessing there needs to be some sort of depth, so a video or photo won't work. Maybe a photorealistic mask though...

9. Snapdude posted on 20 Oct 2011, 12:35 2

IR sensor for depth perception, simlar to the microsoft xbox kinect system

22. vette21man posted on 20 Oct 2011, 13:16 2

Does the Nexus have an IR sensor? Do ANY phones have this?

If not, what's to stop a photo from working? Taking in ambient light and judging if the face is receiving the correct "shine" on their forehead? Does it require you move your mouth or eyes for validation? Could I just take a blown up photo of the person, cut out a hole for the mouth and eyes, then smile a cheesy grin and have access into my bud's Nexus?

Proximity sensor is IR based, isn't it? Could the range on that help with Face Unlock?

indeed the prox sensor is usually IR based so in theory yes if they bumped up the specs of the prox sensor it could double as an IR sensor to aid in facial recognition

i assume it has some way of "measuring" distances from eyes to nose n mouth n such and looking for slight variations. Im not really up on this kinda tech, so its just a guess.. but it sounds good :)

51. Diablo2424 posted on 21 Oct 2011, 07:01 0

I'm not sure about a video, but my friend and I were talking about using a photo and determined the technology probably works on micro-movements that all human beings would do. For example noone can stay %100 completely still, you are always moving, and so is your facial expression, it's never %100 still, so it probably uses these micro-movements to determine if it's really your face trying to unlock the phone. A video might possibly be able to fool this system, however that video would have to be VERY clear, no glare on the screen it's being played back on, same depth (as mentioned below) and same facial expression. That's a pretty serious video you'd be requesting of someone, lol.

Either way, we just have to wait until it's released to see! :-)

23. vette21man posted on 20 Oct 2011, 13:23 1

You would need 2 lenses to read that it is indeed 3D. So 2 phones out of all Androids would be able to do this (not Nexus).

Side note, say you have 2 EVO 3Ds...play a 3D video on device A, record 3D video on device B of the 3D playback on device A...Will the video look 3D on device B?

11. remixfa posted on 20 Oct 2011, 12:37 7

what if we just chopped the head off and wiggled the mouth infront of the camera?

I tried that with the beta and it worked fine

12. bossmt_2 posted on 20 Oct 2011, 12:38 5

If someone goes through the effort to make a perfect 3D replica of your face, they deserve to unlock your phone.

On that note, I'd assume there's a slew of reasons a picture wouldn't work, from the lighting not being proper, to curving of the picture, reflection off the picture, who knows. Aside from a picture of you, I don't think any other way of hacking it would be highly practical

Those are some ugly chicas at that pittpatt.com website.

25. Mobile-X-Pert posted on 20 Oct 2011, 13:47 1

My N8 is able to recognize people faces on the pictures and even on the newspaper with the face detection feature, so I guess it is possible that a picture of you can unlock the phone.

30. rd_nest posted on 20 Oct 2011, 14:44 0

hmm...

simple actually, the phone unlock system has a secondary option - You can add a simple pin code or you could also add a unlock pattern like in older androids. if facial recognition fails, the secondary option pops up.

31. Alantef posted on 20 Oct 2011, 15:01 2

not you....you didn't say anything funny....so this doesn't apply to you

36. roldefol posted on 20 Oct 2011, 16:26 1

Just get plastic surgery to look like them & reprogram the phone.

49. MichaelHeller posted on 21 Oct 2011, 00:37 2

I think we're getting some good ideas here. So far, we have to ask Google about: photorealistic masks, video, and Face-off scenarios.

50. Thump3rDX17 posted on 21 Oct 2011, 00:56 0

don't forget look a likes! o:

52. vette21man posted on 21 Oct 2011, 07:58 0

Agreed, and as proven in the original demo, it won't even let in the actual owner of the phone. Now THAT is security.

everything is better native baby.

Yes there is one on the market ,but many will work with a picture this one won't , this one is also embed in the system, as always from google the"facelock" is an invitation for devs to do something cool with it. Learning how it works assures an app could use your face for tons of other things All it needs is creative mind
