Projector-based 3D face recognition. Nifty. Shines an IR dot pattern onto the face, recognizes with that, works in the dark. Seems on continuously, wonder how much power draw.
- sunsetMurk 9y agoI'd bet ~30 days with this in the public's hands we will see headlines like "How to beat iPhone's facial recognition with X". There are some crafty folks out there--
- simonh 9y agoThey look like they worked hard to cover that, even training the network to reject 3D face models done up by Hollywood makeup artists. It's hard to see how you'd spoof it better than that.
- sgarman 9y agoThis is a fundamental issue with developing secure software/tech in a private. You have to hope you are the smartest team in the world and that you thought of everything. It's you vs everyone else.
- pi-rat 9y agoDoesn't really have to look like a hollywood mask though, fooling neural networks is a growing area of research these days: http://www.evolvingai.org/fooling http://www.evolvingai.org/fooling There are probably many redundancies in face ID, but I wouldn't be surprised if some interesting techniques for fooling it show up.
- dgreensp 9y agoThese approaches assume you have access to the trained neural network weights, i.e. that it's a "white box".
- manmal 9y agoSince it's based on neural nets, I think there might be ways, but they will likely not work consistently.. they will only work in certain conditions. Also note that they also track head position (must face camera) and check the eyes (must be open and look at the camera).. this will be hard to get right all at once.
- monkmartinez 9y agoSunglasses?
- jareds 9y agoI'll be surprised if this works for me as a blind person. There's no way I could directly look at the camera. I don't need the iPhone X since I don't care about camera quality, but if touch id starts being removed from all new iphones I will be giving Android a long hard look.
- theshrike79 9y agoIs Android support for visually impaired users still as spotty as it used to be?
- jareds 9y agoI'm not sure. It was truly bad in the Android 2.3 days. I own a Moto E since it was cheep and I was curious if Android had improved. Running 5.1 was pretty accessible, but was slow which is expected since it's a low end phone. Android apps on a chromebook work pretty well, but who knows how that will translate to a modern mid range Android phone.
- MBCook 9y agoApple's pretty good at accessibility, they may have thought of that with one of their settings. They seem to work so hard at making sure all their products work well for people various levels of vision problems I have to believe they would've done something. After all even the Apple TV has support for people with total vision loss. I don't see why they'd break their flagship product.
- avn2109 9y agoAlso, what happens when I shave my big beard off? :( Or grow it bushier?
- dewey 9y agoThey had that as a test case in the video and said that the phone will learn that.
- theshrike79 9y agoAs long as you keep unlocking your phone while your beard grows, it'll learn your new face.
- avn2109 9y agoFine, but how can it possibly learn while I shave the beard off?
- theshrike79 9y agoI think it depends on the amount of beard you shave off. Worst case is that you have to use the passcode and it'll relearn your beardless face.
- plandis 9y agoYeah I'm not sure if that's new or not but it's the first I've heard of it. That seems like a really cool idea.
- kuschku 9y agoIt’s technically an older concept, and has been used previously for other kinds of 3D scanning of people, but this seems to be the first mainstream miniaturized version of this.
- cyanbane 9y agoIsn't this what the Kinect does to determine who you are and sign you on for the Xbox? I think that's been around for 4-5 years. Impressive they can do it all on the phone.
- patzol 9y agoApple actually bought company (PrimeSense) that was responsible for Kinect sensor and it seems to work the same way. It's just impressive that they manage to fit it inside these size phone. Google tango devices are bigger.
- joezydeco 9y agoIt is: https://www.youtube.com/watch?v=dTKlNGSH9Po https://www.youtube.com/watch?v=dTKlNGSH9Po
- SigmundA 9y agoThey bought the company Primsense that did the original Kinect in 2013, seems obvious now why.
- benbayard 9y agoNot unique, but fitting that hardware on a phone is pretty incredible.

- Jeremy1026 9y agoLikely only on when the screen is on, and the device is locked. So maybe a total of 5 minutes a day?
- apetresc 9y agoI'm not a camera hardware expert, but my understanding is that (like most things), the booting process uses up more power than the same duration of time in a steady state. So the "five minutes" number is misleading; if that 5 minutes is broken up into hundreds of discrete startup cycles (which is not at all unrealistic - people instinctively check their phone a lot more often than they think – and there's no way for the phone to tell whether you're turning it on to glance at the clock or to unlock it until after it's turned the camera on), then it's a significant amount of power draw.
- ctdonath 9y agoThere were indications during the presentation that it actually runs face recognition often, including as a power-saving technique (sounded like it would turn screen off when you weren't looking at it, back on when you do).
- simonh 9y agoIt probably activates when the phone is raised or held at certain angles. They're pretty smart at recognising the ways devices are held and moved, such as with the watch activating when you raise and turn your wrist to check the time. Also when Craig demonstrated it, he raised the phone, looked at it and also swiped up from the bottom. If that's how it works, they might activate the sensors at the beginning of the swipe gesture.
- nardi 9y agoRegardless, they said the phone gets 2 hours better battery life. That's pretty remarkable.
- Angostura 9y agoFantastic for when I'm skiing or in bed with half my face stuck in a pillow.
- theshrike79 9y agoMaybe turn your face 45 degrees for a second? Or just use the passcode if you're unable to do that for some reason.
- viraptor 9y agoWhen you're skiing you're also unlikely to use touch id.
- Angostura 9y agoThis is a very fair point.
- sixothree 9y agoCan be used by police to unlock your phone by pointing it at your face.
- esMazer 9y agoTHIS is all I could think since the rumors started. If someone wants to steal your phone can't they just hold you for 1 second and point the phone to your face to unlock it?
- lathiat 9y agoiCloud Activation Lock still applies unlocked or not, you need to enter passcode to disable it. Also if you close your eyes or look away it wont unlock, arguably harder to force than putting someones finger on the phone
- pi-rat 9y agoSure, but it might be stronger than fingerprints. If your eyes look away it won't unlock. Also, there's a "cop button", in iOS 11 you can disable touch/face id by pressing the power button quickly 5 times.
- stcredzero 9y agoThey should have an option to lock your phone, disabling face recognition, on voice command.
- foodstances 9y agoHow is that any different than them forcing your finger onto a TouchID sensor?
- daxorid 9y agoIt's not. Anybody who uses iPhone authentication methods other than a random six digit passcode with a ten-attempt wipe is asking for trouble.
