What is face ai di. Face ID: what is this technology and is it so secure? Face ID does not work - disable "Attention Recognition"

Smartphone manufacturers are constantly trying to figure out how to improve the security of user data. Several years ago, smartphones introduced the ability to unlock devices using fingerprints, and now face unlocking is being actively implemented. Today we will tell you about Face ID and answer questions such as: what is Face ID, why this technology is needed and how to set it up.

What is Face ID on iPhone and iPad

Face ID became available on iPhone X last year and iPad Pro this year. She came to replace and represents the unlocking of the device by scanning the face. One glance away is enough front camera iPhone or iPad for Face ID to work and the device is unlocked.

Face ID completely replaces Touch ID, and is used in all situations that previously used fingerprint scanning:

• Unlocking the device;
• Authorization of purchases in App Store;
• Apple Pay confirmation;

Face ID is now available on devices such as the iPhone XS Max, iPhone XS, iPhone XR, iPhone X, iPad Pro (12.9-inch, 3rd generation), and iPad Pro (11-inch).

How Face ID works

Face ID isn't a front-facing camera, it's a separate TrueDepth camera system. The sensors project more than 30,000 points onto the face, through which a structural map of the face and an image in the infrared spectrum are compiled. Thus, you can unlock the device even in the dark.

Face ID technology to unlock the device works when you pick up the gadget or unlock it by touching the screen, as well as when receiving notifications. The response time, especially in devices of 2018 (iPhone XS, XS MAX, iPad Pro), is almost instantaneous, but there is still a slight delay. However, when used, it is almost invisible and does not cause discomfort.

Face ID adapts to changes in appearance, be it makeup or unshaven. She will also be able to recognize the wearer if he is wearing sunglasses, a scarf, a hat or lenses. Although, if you “registered a face” with a long beard, and decided to shave it off, the iPhone or iPad will ask you to enter a password to verify your identity. If the password is correct, the system will update the data and you will continue to unlock the device as before.

To pay with Apple Pay and Face ID, you need to double-click the side button. The Face ID scanner will launch. After successful completion, touch the device to the terminal to make a payment. As you can see, the process is no different from paying with Touch ID.

How to set up Face ID

You are prompted to set up Touch ID when you turn on your device for the first time. If you haven't, then go to Settings - Face ID & Passcode.

Click Set Up Face ID. Hold the device upright and move your head in a circle. A green circle will show which area is ready and which still needs to be scanned. Click Next and scan the face again.

Which is better than Face ID or Touch ID

Face ID is safer than Touch ID. There are many ways to fake a print, but faking a face is almost impossible (a photo on paper will not fool Face ID). In addition, if the owner of the device is asleep, and another person tries to bring the device to his face and unlock, then he will fail, since when unlocking the user must have his eyes open (even if there are sunglasses on top).

When we want to use the device, it usually looks at us, and Face ID will automatically recognize the owner. This is more comfortable than putting on your finger, which may not work due to being dirty or wet, or simply touching the scanner too badly. And in winter, Face ID easily unlocks the device, and for Touch ID you will have to take off your gloves or enter your password.

The only drawback is that if the device is lying somewhere on the table, your face does not fall into the field of view of the sensors. In this case, Touch ID is more convenient.

As a result, Face ID wins in every respect: safety and convenience, except in rare situations.

Face ID is an innovative feature that uses facial recognition to unlock your smartphone. It was first introduced with the iPhone X and replaces Touch ID. Face ID is only available on iPhone X, so older model owners can't use it.

Fortunately, there is now a way to use Face ID on any iPhone. This is possible thanks to the jailbreak application Appellancywhich mimics the Face ID feature on older iPhones. Through of this application you can unlock the smartphone with your face.

Here's how to use the Appellancy app on iPhone with iOS 11.

How to useFace ID on anyiPhone

Step 2: When the source is added and all its files are downloaded, search for the tweak Appellancy and install it.

Step 3: Return to your home screen and launch the app. Click the "+" button in the upper right corner of the screen to add a new user. Here you can take a photo of your face so that the application can recognize you.

The more photos you take, the better face recognition will work. You can photograph your face from many angles. You can also add the faces of your relatives so that they can also unlock your smartphone.

Step 4:All is ready. Now, to unlock your iPhone, simply hold it up to your face so the front camera can recognize it. After a second, the device will be unlocked.

Now you can add Face ID to your iPhone too. It's important to note that the app only mimics the Face ID feature, it doesn't add it to the device. The app is not as secure as Face ID, much less Touch ID or passcode. You can only play with them or surprise your friends.

Tweak developers are getting more creative and adding more new features to older iPhones. If you still haven't installed the jailbreak on your device, you can use our step by step instructions About, .

The facial recognition system introduced in the iPhone X (iPhone 10). Used to unlock your smartphone and pay for purchases using Apple Pay. It is a complete replacement for the fingerprint scanner.

Main materials

When Apple introduced Face ID, it called it the most convenient and secure method of identification that modern smartphones have ever equipped. The new face recognition interface has surpassed even, not only increasing the reading speed, but also reducing the percentage of false positives when the smartphone did not want to remove the lock. Most users really appreciated the innovation and now do not understand their life without Face ID. That's just the Chinese coronavirus 2019-nCoV ruined everything.

Prohibitions on the use of certain developments used in apple devicesare completely standard practice in many countries around the world. For example, in Russia Ultra Wideband technology is blocked, in China - several services at once like iTunes, + and Apple Arcade, and in the United Arab Emirates - FaceTime video calling. But since none of this is key function Apple branded gadgets, Cupertino is quite loyal to the desire of local authorities to limit the access of their citizens to its developments. But how will the company react to the Face ID ban, which is massively adopted by the US city government?

Despite the fact that Apple rarely directly asks its users about what they expect from the company's future products, it cannot be accused of being uninformed or lagging behind trends. In Cupertino every now and then they conduct all kinds of research, the result of which is an accurate hit on the target. So it was with Apple Watch, whose success, and even with the iPhone XR, which, although it came out quite a compromise, in the end. The love of users for Touch ID has not been ignored either.

The decisiveness with which Apple replaced Touch ID with Face ID in 2017 surprised not only retrogrades, but also technology fans. To many, the abandonment of the usual method of identification seemed even more radical than the release of the 5.5-inch one. In the end, then users were offered an alternative in the form of a more compact model, and in the case of biometrics, they were not given a choice at all. Probably, this is how Cupertino wanted to emphasize their willingness to mercilessly part with old technologies, but I personally would still like to return Touch ID. And that's why.

Have you ever heard the opinion that everything new is well forgotten old? So I hate him, especially when someone tries to convince me of the opposite, drawing parallels with various facts from history. In such cases, I recommend opponents not to call what has a historical prototype new, or, if the analogy does not hold out, not to cite it as an example at all. Most of the time my theory works pretty well, but sometimes it fails, like now.

Apple is rumored to be due this fall. The updated laptop will receive minimal bezels around the display, a new scissor key mechanism and top-end processors of the latest generation. The new product will primarily be aimed at professionals - hence the high base price of $ 3,000 (~ 200,000 rubles). But in my opinion, there is another option that Apple should implement in the MacBook Pro is Face ID.

Everything you need to know about Face ID on iPhone X.

One of the most impressive features of the iPhone X is its Face ID scanning technology. Apple engineers have come up with something really amazing that can revolutionize the field mobile devices... In this article, we talked in detail about the Face ID function, how it works, how to configure it, and many other features.

What is Face ID?

Face ID is Apple's new authentication system that allows you to verify your identity to unlock your iPhone or pay for purchases by just looking at your smartphone. Identity is verified by scanning the face and comparing it with a previously recorded structural map of the owner's face. Face ID was first introduced with the iPhone X, Apple's 2017 flagship.

How does Face ID work?

Ultra-precise and fast face scanning technology is made possible by the combination of advanced software and hardware developments from Apple. A key hardware development is the TrueDepth camera system, which includes:

• Point projector... It projects over 30,000 invisible infrared points onto the user's face, which are then used to create a mathematical model.
• Infrared camera... It reads the point structure of the face and creates an image in the infrared spectrum and places this data in a special module of the A11 Bionic Secure Enclave processor.
• Infrared emitter... Shoots an invisible beam of infrared light onto the face, allowing accurate face scans, even in complete darkness.

Thanks to its unique components, the TrueDepth camera projects over 30,000 invisible dots onto the face, analyzes them, and produces a detailed structural map and infrared image of the face.

The map is then passed to the A11 Bionic's Secure Enclave, where the infrared image and depth map are converted into mathematical representation. It is this representation that becomes the face of the owner for the iPhone X.

When Face ID remembers the user, the function "takes over" the iPhone X. Each time you attempt to authenticate, the face is scanned again, a map is drawn up, and then its mathematical representation. The latter is compared to a reference view already stored in the Secure Enclave module. The iPhone X spends a split second on all these absolutely incredible actions to understand.

I have grown a mustache / wearing unusual makeup, what will Face ID do?

Minor facial changes, be it thick hair or custom makeup, won't be a problem for Face ID. In addition, the function easily recognizes users wearing glasses (including sunglasses), scarves, hats and contact lenses. At least that's what Apple says. Whether this information is reliable will be found out after the iPhone X goes on sale.

To be fair, we note that Apple does not call Face ID something magical. The company explicitly states that if the face changes significantly, Face ID will not be able to recognize the user. In this case, the iPhone X owner will need to enter a passcode. After successful identity verification, the system will update the face data.

How do I set up Face ID?

In order to start using Face ID, you need to perform the initial setup of the function and scan the face. To do this, go to the menu “ Settings” → “Face ID and password"And click" Add face“. After that, a special front camera screen will start with the crosshair shown, in the very center of which you need to place your face. When the green bar around the camera screen is full, your face scan is complete and you can start using Face ID.

How to unlock iPhone X using Face ID?

Everything is very simple. To unlock iPhone X using Face ID, you just need to look at the device's screen. The scan will be performed instantly and if the face matches the previously saved mathematical face card, it will be unlocked.

What is the best distance to hold your iPhone X to unlock?

During the presentation of the iPhone X, Apple executives boasted that Face ID will be able to recognize the owner of the smartphone even if the smartphone is not directly in front of the user. And indeed it is. A face scan will also be performed in cases when you hold the iPhone X in your hands, but at an angle, and if the smartphone is on the table. The main thing is that the face is in the view of the TrueDepth camera. The scan overview is identical to the FaceTime camera capture overview.

Apple did not talk about this during the iPhone X presentation, but the accuracy of unlocking the device using Face ID will be better if the smartphone is at arm's length (or less) from the face. Therefore, the ideal distance for Face ID to work is less than 50cm.

Does the scan also occur when the screen is “sleeping”?

Yes, you don't have to specifically press the power button and unlock it. When you pick up or touch the screen of the iPhone X, the smartphone automatically wakes up and activates the TrueDepth camera. This allows you to scan as quickly as possible, without delay in pressing any buttons.

Is Face ID Infrared Harmful?

The radiated power of the TrueDepth camera system is extremely low and safe for normal use. Apple has rigorously tested TrueDepth to meet all possible security standards. There is nothing to worry about.

Is the radiation completely invisible?

The infrared glow from the TrueDepth camera can be seen with the naked eye, but only in complete darkness. In other lighting conditions, it will be possible to notice the glow only through the viewfinders of cameras with the ability to register infrared radiation.

Is my face card on Apple servers?

The data used by Face ID, in particular the mathematical representation of your face, is stored encrypted in the Secure Enclave, which is part of Apple's revolutionary A11 Bionic processor. In other words, the face card is only stored on your device and is not sent anywhere. The Touch ID fingerprint scanner works exactly the same way.

What actions can I use Face ID for?

You can use Face ID on iPhone X to:

• unlocking iPhone,
• authorization in applications that support this technology,
• making purchases in the App Store, iTunes Store and iBooks Store,
• identity verification when shopping with Apple Pay.

What is the chance that another person will unlock the iPhone X with their face?

The likelihood that your iPhone X will be unlocked via Face ID by another person is 1 in 1,000,000. In this case, this person will have only five attempts to authenticate. If they all fail, iPhone X will ask you to enter your passcode.

Can I unlock Face ID while a person is sleeping?

No, facial recognition with Face ID only happens when the person is looking at the device. It is not possible to authenticate with your eyes closed.

So, can you forget about entering a password?

Despite the fact that Face ID works very accurately, it constantly learns and remembers your appearance, reacting to its changes, you will not be able to forget about the need to enter your password forever. Moreover, to be able to turn on Face ID on the iPhone X, a password must be set. It will need to be entered if:

• More than 48 hours have passed since the last unblocking.
• iPhone X just turned on or restarted.
• There were five unsuccessful attempts to unlock using Face ID.
• Face ID has been blocked through Find My iPhone.

Note that there is nothing new in this regard. All the same points were relevant for Touch ID.

How much will it cost to repair a TrueDepth camera?

Apple did not even disclose the approximate cost of repairing the TrueDepth camera system, but emphasized that infrared emitters can be damaged when repairing or disassembling the iPhone X. However, the company strongly advised iPhone X owners to contact only Apple or its authorized service centers in the event of a breakdown.

As with the Touch ID fingerprint reader, the TrueDepth camera system has built-in components to detect unauthorized modifications. This means that if non-original components are detected in TrueDepth, the camera system will be disabled and face function The ID will stop working.

How to turn off Face ID and unlock by entering a password?

If you don't want to unlock iPhone X using Face ID, you can turn off this option. Go to the menu " Settings» → « Face ID and passcode» → « Use Face ID"And disable the" Unlocking iPhone».

How do I turn off Face ID completely?

You can turn off Face ID completely on iPhone X and delete your face card data at the same time. To do this, go to the menu " Settings» → « Face ID and passcode" and press " Reset Face ID". Note that all data used by Face ID is deleted and when performing a full reset iPhone X.

Surely many users who are going to buy an iPhone X are concerned about the question - how clearly does Face ID work on the new flagship? Can he be fooled by, for example, showing a photograph of the owner or creating a wax figure of him? Agree, all these questions directly relate to the security of the smartphone and we simply have to deal with this in detail.

Ways to cheat Face ID on iPhone X

Let's figure out in what cases Face ID can be removed without the knowledge of the owner of this iPhone 10 and vice versa - if the owner's face changes, will he recognize it.

1. If he has a twin brother (sister) - can he cheat a smart piece of iron?
2. If the owner grows a mustache or beard, can he unlock his smartphone?
3. If you reproduce the owner's face in any way (cast, wax figure) - will this deceive the smart system.
4. Will an attacker be able to unlock an iPhone X using a printed A4 photo of the owner (hello Galaxy Note 8)?
5. How Face ID works in the dark - is it possible to unlock the device at night.
6. Will someone be able to unlock the smartphone by bringing the sleeping owner to the face?
7. How do accessories affect - will the iPhone 10 be able to recognize the owner if he is wearing glasses, a hat or other clothes.

The video below partially answers these questions.

Video

Based on tests:

1. A twin brother or sister can unlock iPhone X in some cases, but not always.

2. Apparently, such a probability is embedded in an intelligent system, and in this case, recognition occurs at other points. But you will need to enter the password the first time in order to add a new element (mustache) to the system.

3. This method will not work. The system will not release the lock, even by the silicone impression of the owner's face.

4. No. The attacker will not be able to unlock iPhone 10 from the photo (hello Galaxy Note 8 again).

5. Face ID works great at night, because the 3D face scanning system has 30,000 points that are emitted in the infrared spectrum and the presence of light in the room does not matter.

As you can see, the system identifies in the dark not only the points of the face, but also the body, clothing, etc.

6. It is also impossible to unblock the master's sleeping face. This video clearly shows everything.

7. Face ID recognizes its owner in clothes, glasses and other accessories. Even if the glasses are with tinted glass, there are no problems. However, if it is great to wrap a scarf around and leave only part of the face, the system will certainly not be able to see and recognize its owner, since there will be too little data for analysis.

conclusions

The new Face ID system in the iPhone X, while not perfect, works just fine and is Apple's most unique and revolutionary technology to date.
