@braddwyer is me :) It gives you about 15 fps of depth data

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

You know how some F2P games will allow you to watch video ads in order to e.g. earn extra in-game currency, activate a point multiplier, etc? As it stands, you can start one of these ads and then turn your phone upside down, or look away. How long until an advertising provider makes use of the attention API and makes it so that you can't look away? Seems bleak.

I called this on the day they announced all this stuff. It's definitely going to happen.

What’s interesting is that on the previous security method - fingerprint - no data was shared with apps. If your face is now a security feature and the data is being shared with apps, that sounds like a security leak. If an app collects your face data, can that data be subpoenaed by a court to attempt to unlock your phone? If a court could work with an outside party to use subpoenaed face data to 3D print your face,…

But face data is not shared with apps for security/unlock purposes. Access to the live face data stream is provided for features like silly Snapchat filters ("turn your face into a lion" type crap) which the user may opt in to.

The problem is, apparently, the opt in question is "do you want to allow this app to use the camera" not "do you want to allow this app to use your face 3D measurements data."

The FaceID camera is infrared and can see in the dark [1]. According to the Post "Once you give it permission, an active app keeps on having access to your face until you delete it or dig into advanced settings. There’s no option that says, “Just for the next five minutes.”" So a random developer can (kind of) look at us when we turn the light off. Not only that, those cameras work also in the sunlight. You can go on…

"Once you give it permission, an active app keeps on having access to your face” Isn’t the definition of an active app, one that is open and in the foreground? The minute the phone sleeps, or the app is put into the background, access becomes more at Apple’s discretion. I’d expect an app running in the foreground to be able to keep using the camera as long as needed.. Or is your point more: allowing once allows it ev…

I have no direct experience of iOs but according to the post it's as you wrote. It could be an app that needs the camera once for some sensible reason, then it can use it forever when it's active even if it wouldn't need it from the point of view of the user.

> I'm honestly less worried about Apple than others. That's a pretty low bar. Yes, Apple at least gives lip service to security which other companies don't even bother to do, but Apple has had some pretty major security screwups lately (three in the last few weeks). You might be less worried about Apple than the competition, but you'd do well to be somewhat worried about them nonetheless.

Two other issues I'm worried about with iOS: - MAC address tracking (RTS packets thrwart MAC randomization[0], not immediately clear if WiFi is fully off[1]) - All-or-nothing access to photos on the phone (append-only for apps that request it) Discord in particular is bad for the photo permission, as I don't trust China's Tencent with access to all the photos on my phone (which can include lots of frequent location i…

Apple changed the WiFi in Control Center behavior in iOS 11.2 to be more clear: https://www.macrumors.com/2017/11/13/ios-11-2-beta-3-control...

"15 Million Credits" from Black Mirror vibes there.

This came to mind to me, too. haha

Something alarming occurred to me: Apple has to be saving all of the faces of people who come into Apple stores and do the Face ID demo. There's no reason for them not to do that, they'd be leaving good data on the table otherwise.

what would be so good about the data?

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…

>The lack of Animoji and front-facing ARKit seems to be a software limitation made for business reasons rather than a hardware limitation.

The A11 chip has dedicated “neural engine” hardware which is used for Animoji and other facial recognition tasks.

How much could be done in the standard CPU on other devices I’m not sure.
