Taking the controversy out of the ?forehead? of the iPhone X (team of those who liked it and consider it a distinctive feature from it vs. team of those who hated / found a horrible cutout), his biggest novelty and the one that is generating more questions certainly his new 3D facial recognition, called Face ID.
And this uncertainty is very understandable, after all, overnight Apple ?abandoned? (not so much, no, Touch ID is still present in all other generations of iPhones still on sale, on iPads and even on MacBooks Pro with Touch Bar ) a consolidated, fast biometric system that everyone trusted with their eyes closed. No pun intended.
In addition, Apple is in that delicate position to show the world, once again, how to do something the right way. Now, there were smartphones with fingerprint readers before the Touch ID came to the iPhone 5s in 2013. Anyone remember them? Incidentally, many forget but at that time there was also a lot of skepticism about Touch ID. , history repeats itself.
To the haters of course, of course, the failure that occurred just in the first public demonstration of Face ID is still a laughing stock for a while even though it has already been extensively clarified. There was no failure of the system itself, there was a failure of the Apple team that prepared the iPhone X unit that Craig Federighi senior vice president of software engineering at Apple used it on stage.
If you want to know more about Face ID, start reading these other three articles from us:
But there is still a lot to go into it, not least because ordinary users will only be able to put their hands on the iPhone X in early November. For this reason, Federighi himself gave two interviews yesterday discussing the operation of the system.
Speaking to Matthew Panzarino, from TechCrunchFederighi started by saying that Apple really cared about using lots, lots of data to train Face ID during its development. Senior Vice President of Worldwide Marketing Phil Schiller at quoted in last Tuesday's keynote that they would have collected more than ?1 billion images? for this, but Federighi says that his colleague went to conservative in the number.
In short, Apple has prepared Face ID so that it works perfectly with the most diverse ethnicities, races, geographic origins, etc. The front camera system of the iPhone X, which Apple called TrueDepth, you simply need to be able to see the person's face with your eyes, nose and mouth. In other words, it * will not * work if part of the face is covered with a mask or, for example, with a burqa (helmet, hat and scarf, on the other hand, it will not be the problem). Federighi associates this limitation with Touch ID when people were wearing gloves or with very sweaty / wet fingers.
The executive also clarified the issue of dark glasses, which we already mentioned in a previous article. He told Panzarino that the problem is not polarized glasses, but glasses with certain lenses that actually block infrared light entirely. In these (rare?) Cases, the person will have to use their alphanumeric password or, alternatively, quickly raise their glasses so that Face ID can recognize it. An option too, as Federighi joked talking to John Gruber in episode # 200 of the podcast The Talk Show, simply buy new glasses. ?
Incidentally, speaking of eyes, one thing that Apple highlighted in the keynote is that Face ID requires the person to be in fact paying attention on the iPhone so that it is unlocked. Obviously, this would not work well for the visually impaired so there will be an adjustment on the iPhone X for those who want to allow Face ID unlocking even without this ?Attention Detection? (facial recognition keeps happening, but without requiring the user to be looking directly at the device). Or, of course, the person may simply not use Face ID as a whole.
Apple promotional images and videos may also have given the wrong impression that the iPhone ?illuminates? the user's face in the dark for Face ID to work. This will not happen; in the dark, Face ID works using only the dim light of the device's own screen on the person's face combined with the data collected by its IR sensor, which are processed in fractions of a second by the A11 Bionic chip. And that works perfectly, according to Apple.
To those who think Face ID s works by lifting the iPhone X straight in front of their faces as if we were on a call via FaceTime or taking a call selfieFederighi also guarantees that this * will not * be necessary. The system recognizes the user by simply having the device be insured in a natural way, even ?at very extreme angles?. The TrueDepth system only needs to be able to see the elements of the person's face to work, and that's it.
Another very important aspect to note regarding velocity Face ID. Many who saw Apple's presentation and / or watched videos of journalists in the hands-on after keynote they thought that Face ID would be slower than Touch ID. The problem, a, that everyone was still demonstrating / testing the feature in a somewhat robotic way. Federighi claims that it is so fast that you just need to pick up the iPhone and immediately swipe from bottom to top to access the home screen. At the same time, Face ID recognizes the face and unlocks the device. This is certainly something we will test when we get our hands on iPhone X.
Gruber also asked Federighi why it would be necessary to slide up instead of just looking at the iPhone X and unlocking it. For the executive, people who are imagining this did not even realize that sliding a finger there is very natural and, if it happened directly, the user would no longer be able to simply look at the time, check their notifications or use the shortcuts. flashlight (new) and camera. Furthermore, iOS does not necessarily take the user to their home screen with app icons; if you last locked your iPhone within an app, when you unlock it you return to it. This would mean that each time the person picks up the iPhone, they would not know exactly where they would be taken.
Federighi also reiterated Apple's concern about security, saying that even if she wants to be able to collaborate with government / security agencies because all the data on the user?s face is stored locally in the Secure Enclave iPhone X. Apple does not send facial recognition data to the cloud in order to improve Face ID, not even anonymous.
In addition, Face ID can be quickly deactivated by the user in an unusual and / or dangerous situation by pressing and holding the side buttons for a few seconds, something you can do without even taking your iPhone out of your pocket. Similar to what happened with Touch ID, the person's alphanumeric password will be requested instead of Face ID if it is not used for 48 hours, if the iPhone is restarted, after five failed attempts to identify a face (which is what happened on stage, with Federighi), among other specific situations.
For developers (and, consequently, for us users as well), the good news that nothing needs to be done to incorporate Face ID support into your apps. That is, applications that were previously protected by Touch ID (such as 1Password, Telegram and banking apps, for example) will automatically work with Face ID without even needing to be updated.

Certainly we will still have more doubts to clarify about Face ID from here until the iPhone X actually reaches the market, but this is certainly a nice overview of what Apple sees as the future of biometrics in the iPhone, but in all your products.
