I've been playing with the TrueDepth Camera APIs on the iPhone X. Some things I've noticed: 1) The ARKit "Face Mesh" seems to be a standard model that is scaled and skewed to fit your face (for example, it ignores glasses, still works if you put your hand in front of your face, etc). It is _not_ a 3D scan. 2) The "TrueDepth" data is not really all that granular. It seems similar to the depth map you get from the rear…

Well that's not what I was sold at the keynote. Has this been verified? I thought my face was being scanned with 30k dots and all that.

Sure. But 30,000 is only 150x200. And not all of them are going to hit your face.

I'm honestly less worried about Apple than others. They've at least made some measures to prove that they are willing to go some distance to protect privacy, even losing ground to competitors in voice recognition. Now thinking about co's like Facebook that not only has access to far more imagery of faces tied to sentiments and moments but have shown time and time again that privacy is a secondary concern AND that the…

Bait.

And switch.

Oh but they won't is not any kind of safeguard at all. We have no idea who will own apple in 10 years time, the entire management team could be changed. Even if you trust apple now, which is probably naieve, you're trusting all possible future apple. That's just crazy. Insert any company large or small in the place of apple and it is precisely and exactly the same. Apple are no different.

I just tried using Animojis with the TrueDepth camera covered. After a second the frame rate drops significantly (to roughly 10 fps) and the character's eyes glitch out. I'm convinced Animojis are doing something with the TrueDepth hardware. It still tracks head movement with just the camera, but its significantly slower and more error prone.

Initials reports suggested Animoji worked with the TruDepth camera covered, but detailed reports of subsequent experimentation have revealed that TruDepth is required at intervals, just not 100% of the time.

> What if I don't want to have my face scanned, but nevertheless need to pick up somebody's lost-phone/detonation-device? Shall I just wear a mask? Well...yeah. If you're out in public and your face is visible, you don't have a reasonable expectation of privacy.

If you are an apologist for what is the equivalent of having hundreds of people in trenchcoats following every person on the planet, detailing their every public move and storing it forever, you don't have any reasonable expectation of your part in the documentary being underlaid with anything but sinister music.

You just described Android.

Haha, cool! Hi :) Given the small size of the laser projector, I imagine natural movement from the phone being hand-held would result in significant displacement of the projected dots over a 1s interval? Have you tried integrating the 15 frames to see what it looks like?

Getting minute, subpixel movements can ironically give you MORE resolution if you process it over time, though you'd probably need some sort of "anchor" points

That doesn’t seem ironic to me.

Re 3) I don’t know any details of Apples implementation, but typically computer vision algorithms integrate data from multiple sensors to generate a 3D model. The more data you have, the more robust the output will be. It’s possible to generate reasonable 3D models of faces from a single photograph. [1] The highest resolution 3D scans I’ve seen are produced by aligning data from multiple high resolution photographies…

A skilled human with a decent tool can also make a pretty good 3D model from one face image in less than 5 minutes. https://youtu.be/Eq0tTzCwXNI

Are you sure. I mean, I know it's tinfoil and the refusal to open phones for the FBI is debunking it, but we've given Apple a database of our fingerprints and now our facial ids as well as constant real time location data of our whereabouts.

It's probably not abused, but how can we really know in the post Snowden world.

So... How do I turn it off?
