One of the main features of the iPhone X was the TrueDepth front camera, which powers Face ID. But it works so-so - to confirm this, we collected 10 problems with the face scanner.
1. Face ID doesn't work in landscape mode
The first owners of the iPhone X note that Face ID does not work in landscape orientation. If you intentionally or accidentally turn your smartphone over, you will not be able to unlock it using your face.
This feature makes the face scanner not as convenient a solution as the fingerprint sensor, which works in any position of the device in space.
This is what Face ID does in it. modern form completely unsuitable for use in future generations of iPad. It’s likely that something similar won’t appear on tablets until Face ID 2.
2. Face ID needs to see your eyes, nose and mouth
The face scanner, which operates on the basis of the TrueDepth front camera, is based on machine learning and artificial intelligence technologies.
With the help of them, it is constantly improving and after a month of use it recognizes you in almost any form - with or without clothes, after a stormy night and with a week’s stubble.
However, as a rule of thumb, Face ID needs to see your eyes, nose, and mouth for it to work. For example, if the latter is covered with a scarf, the face scanner simply will not recognize you.
3. Face ID will definitely blind you in bright sunlight
Touch ID does not work with wet or even just damp hands, or with gloves in winter. This makes the fingerprint sensor useless in some use cases.
Similar weak spots Face ID also has it. For example, a face scanner can be blindingly bright sunlight, falling on it at a certain angle.
You can deal with this by changing the angle of the device and the position of your head. However, certain difficulties may definitely be associated with this.
4. Face ID does not recognize small children< 12 лет
Not long ago, a warning about the operation of Face ID appeared on the official Apple website, which is most directly related to the safety of using the face scanner.
Surprisingly, TrueDepth today cannot cope with recognizing children under 12 years old - at this age they are too similar to each other.
Of course, the percentage of iPhone users of this age is unlikely to be very large, but the situation itself looks strange - it turns out that Face ID can literally be deceived by a child.
5. Face ID doesn't always handle twins
As it turns out, Face ID can be wrong not only with small children, but also with twins. If you have an identical brother or sister, stay away from them.
As the experiences of Western journalists show, technology really does not distinguish some twins - however, this does not always happen.
It has not yet been possible to identify a pattern, but Face ID can distinguish even the most similar ones to our eyes, but confuses others. Most likely, the digital face map is not created in the usual way.
6. Face ID will not save additional users
While I was still using Touch ID, my iPhone had not only a couple of my fingers, but also the prints of my wife and father - just in case something happened.
With Face ID, such a system will not work even if you want to. The scanner built into the iPhone X can only save one face - this is its main limitation.
However, this won't stop you from telling everyone you need your iPhone X password in case of an emergency. Maybe this is for the best.
7. Face ID really wants to see the eyes on you
Western journalists have already noted that Face ID sometimes works strangely. In some cases, it doesn't work until it sees your gaze on itself.
They emphasize that at times you have to look not even at the screen, but directly at the TrueDepth front camera module. Otherwise it doesn't want to work.
As a result, it turns out that the iPhone X thinks that it is not its owner who is looking at it, and prompts you to enter a password. This is incredibly annoying.
8. Face ID can be disabled for security
Oh, by the way, similarly to Touch ID, Face ID is sometimes disabled for security reasons - in particular, if the scanner was unable to recognize your face five times in a row.
A similar situation occurs after rebooting the iPhone X, remote blocking via Find iPhone, and also after using the SOS signal.
In addition, the iPhone X will ask you to enter a passcode instead of using Face ID if the smartphone has been locked for 48 hours or the scanner has not been used in the last 4 hours.
9. Face ID is not needed to protect your data
We have already written that biometric data protection technologies are not needed to make your iPhone noticeably more secure - no.
They are necessary for ease of authentication on the device. Entering your password every time is difficult. But putting your finger on it is a piece of cake.
However, both Touch ID and Face ID are much easier to fool than the number pad for entering a password. In the first case, a rubber finger model is suitable for this, in the second - a twin.
10. Face ID is much slower than Touch ID
If you compare the speed of Touch ID in iPhone 8 and Face ID in iPhone X, it becomes clear that the face scanner is noticeably slower than the fingerprint sensor.
And this is not surprising, because before today Touch ID has survived several generations of the iPhone and today is noticeably faster and safer.
Of course, in a couple of years, Face ID will definitely lose most of its shortcomings, but today it cannot be denied that it certainly has them.
- this is great. Yes, the technology is slower than Touch ID, but when it works properly, you don't even notice it. In a way, it's like magic. And this is still the first generation of the system. Remember how slow the first generation Touch ID was? So it has its own nuances and bugs, like any other new technology.
Face ID works great 90% of the time. If the remaining 10% really upsets you, try following the tips listed below. They may make Face ID work better for you.
1. Don't wait for the castle animation
If you just stare at the locked screen and wait for the lock animation to complete, the unlocking process will take a very long time.
Here's what to do instead: Immediately swipe up from the bottom of the screen, and by the time the home screen opens, your phone will be unlocked. Face ID is designed so that you don't notice it at all. And usually it is.
After a week of tests, we can say for sure that this unlocking method is the fastest.
Perhaps Apple is trying to save battery in this way, but if you just look at the screen and do nothing, the phone rarely unlocks itself.
2. Quick method: touch and swipe in one motion
Most quick method using Face ID - using tap-to-wake. You don't even have to reach for the side button to activate the screen.
If your phone is on the table, or the display doesn't turn on when you pick it up, simply tap the bottom of the screen and immediately swipe up. You will unlock your phone very quickly.
3. HoldiPhoneon distance 25-50 cm
Face ID works best if you hold the phone at a distance of 25-50cm from your face. If this is too far for you, move your phone closer or change the angle. When you're lying in bed and holding your smartphone too close to your face, the technology is unlikely to work.
The easiest thing to do if the authentication attempt fails is not to change the angle, but simply move the phone further away from your face or vice versa.
4. Keep your sensors cleanTrueDepth
Over time, the area of the screen where the sensors are located (the notch) may become covered in dust. Especially if you carry your phone in a case. Wipe the display with a microfiber cloth from time to time.
5. Disable recognition attention
If you often have to unlock your phone without looking at it: in the car, when it's on the table, etc., turn off attention recognition.
Go to Settings -> Basic -> Universal access -> Face ID and password code and disable the option Demand attention ForFace ID.
Now Face ID will work even when you are not looking at the display. However, this increases the risk that someone else can break into your phone while you're sleeping or not looking at it.
6. Avoid sun protection points
Some Sunglasses do not transmit infrared light, which is used by Face ID to recognize attention. If you often wear such glasses due to work, then it is better to disable this function (discussed above).
7. Avoid sunny Sveta
Direct sunlight prevents Face ID from working properly, like any other camera. If you're trying to unlock your phone outside, turn around so that the sunlight doesn't shine on either the camera or your face.
8. After an unsuccessful attempt enter password
If Face ID authentication fails, do not try again, but instead enter your password. When you enter your password, Face ID learns and remembers your face.
9. Enable notification previews on your lock screen
For many people, Face ID doesn't work very well when the lock screen is open. If you immediately swipe the screen, everything works fine. In this regard, problems arise. For example, the inability to quickly see the content of your notifications on the lock screen.
To solve the problem, go to Settings -> Notifications -> Show thumbnails -> Always.
Now you don't need to use Face ID to view the contents of notifications.
10. Reset settingsFace ID
The last salvation is to reset all Face ID settings. This will remove all data about your face.
X curbed the ardor of enthusiasts and gave more reasons for skepticism. The funny embarrassment that happened to Apple Vice President Craig Federighi instantly became known to the whole world, after which people began to doubt the reliability and security of Face ID.
In this article, we will tell you why this technology is needed and discuss whether there is reason to fear that one day the iPhone X will not be able to be unlocked.
Face ID is a program that can identify a user by face. The True Depth front camera is responsible for this. The camera is located on a small “island” in the front, not covered by the display – geeks aptly dubbed it the “bangs”. "Bangs" hides great amount sensors and electronics.
These sensors enable Face ID to work. When the user takes the smartphone in his hand, an infrared sensor (flood illuminator) is activated, the task of which is to recognize whether there is a face in front of the screen. If there is a positive response from the infrared sensor, the dot projector is launched - the laser projects 30,000 dots onto the face in front of the screen. Finally, the infrared camera reads those points that are clearly visible and compares them with the 3D image the user originally took. If the technology “recognizes” the owner, the processor is given the command: the gadget needs to be unlocked.
The same system is used to create animoji, which are capable of copying the user’s facial expressions.
For Face ID, the most important thing is to see 3 elements of the user’s face: mouth, nose and eyes. If an iPhone X owner changes his hairstyle or grows a beard or mustache, this will not confuse Apple technology. It’s another matter if a person puts on dark glasses, takes his eyes away from the camera, closes them, or covers his mouth with a scarf - in these cases, Face ID may be powerless.
Apple has installed a small coprocessor in its flagship, thanks to which Face ID will remember the face more and more clearly over time. The longer you use your smartphone, the faster facial recognition works and the less accessories like glasses confuse the program.
What is Face ID technology for?
Using Face ID, you can:
In short, Face ID completely covers the functionality of Touch ID.
How to set up Face ID?
Setting up Face ID should only be done by thoroughly stretching the cervical vertebrae. You can find the required option on your phone by following the path “ Settings» — « Face ID and password" Once in the menu of the corresponding settings section, you need to act as follows:
- Click on " Setting up Face ID» and place the device at a distance of approximately 30 cm from your face. A round frame will appear on the screen - make sure that your face is in the center.
- Slowly move your head in a circular motion so that the program can form a structural (3D) image. By the way, for those who, due to physical limitations, cannot turn their heads, Apple has provided a different algorithm - you can activate it through the settings section “ Accessibility options».
- Click " Further" and repeat the circular motion.
- When a notification appears on the screen that Face ID is configured, click on “ Ready».
This useful animation is posted on the Apple website:
You can only add one face to Face ID on iPhone X. Setting up a smartphone so that any family member can unlock it using their face will not work.
Is Face ID really safe?
Apple claims: the probability that an iPhone X will make a mistake when unlocking by face is 1:1,000,000. For comparison, the probability of a Touch ID error was 1:50,000. In order to explain the incredible security of Face ID and relieve users of doubts about the advisability of using the program , Apple said the following about the technology:
- A unique 3D facial image cannot be stolen. It is stored in the memory of the Secure Enclave coprocessor on the device itself and is not sent to Apple servers.
- Face ID won't "buy" into a photo because infrared dots are projected differently onto a flat image. In this aspect, Apple certainly outperformed, whose Face Unlock technology was easily fooled with a photograph.
- You can’t fool Face ID with masks and plaster models either. Apple checked.
Despite all this, Face ID technology is far from perfect. Specifically, she failed the “twin test.”
There are no guarantees that the smartphone cannot be unlocked by using a 3D mask. Modern technologies They allow you to make one from just one photograph of a person. From this point on, Touch ID is even more reliable: hollywood movies they lie - the fingerprint sensor will not respond to the finger of the deceased, a severed finger or a prosthesis. For the scanner to work, you need a surface electric charge, which only living tissue provides. In the case of Face ID, there is no direct contact - this gives scammers room to experiment with a 3D printer.
In addition, Secure Enclave cannot be called invulnerable. Back in mid-2017, they managed to hack the coprocessor and made the decryption key public (as reported by threatpost.com). Apple has patched up this “hole”, but users of Apple technology have already begun to have doubts about how responsibly the Cupertino people take to ensuring the safety of personal data.
5 Important Points a Face ID User Should Know
It is important for iPhone X users to remember that Face ID:
- Will not be able to recognize the child. For technology, all children under 12 years of age are (approximately) the same person.
- Doesn't like sunlight. There is a possibility that the True Depth camera will not be able to perform its functions in sunny weather. The user will have to find a shadow or at least change the angle of the device in order to unlock the phone using the face.
- Doesn't work in landscape orientation. At least for now. The iPhone must be held vertically.
- It will turn off if it fails to recognize the user's face 2 times in a row. The iPhone owner will have to enter a password.
- Not the most dynamic way to unlock a smartphone. Touch ID is much faster - like any other fingerprint scanner on modern mobile phones.
It is obvious that many of the described shortcomings will be eliminated as the program is updated and improved. The same Touch ID, which is now an effective tool for protecting a smartphone, was mercilessly criticized by users at first.
Conclusion
The 1:1,000,000 ratio that Apple loves to flaunt looks extremely dubious. A study led by the University of Washington found that even the most powerful modern systems facial recognition systems show an efficiency of 98% - that is, they are wrong at least twice out of 100 times. The analysis is carried out permanently, the data is constantly updated - perhaps someday a system will appear on the list that works accurately in 99.9999% of cases, but modern level technology development looks like a utopia.
However, even in its current state, Face ID copes well with iPhone protection. Sometimes the program is even too vigilant, which explains the incident with Federighi. According to Apple, in the time leading up to the presentation, Face ID had to try to identify a huge number of individuals, so it decided to play it safe and ask for a password.
Yesterday, a new video interview with the notorious young rapper from Ufa, performing under the pseudonym Face, appeared on the official channel of video blogger Yuri Dud. And so that you don’t torment yourself by watching this too long and obscene conversation, we have collected for you all the most important and interesting things here.
Face doesn't stand on ceremony at all
Ivan (this is his real name) shamelessly talks about how he can easily attack a person with his fists if he doesn’t like something. The most obvious example was the incident during a concert when Face beat a man from the crowd with a microphone because he was showing his middle finger. Yes, everyone has haters, but this is not a reason to break a person's head. Or is there something we don't understand?
Face does not have a higher education
Of course, this is his choice, because now he is on hype, and he simply does not have extra time. Face openly declares that he does not consider it necessary to receive it.
“I don’t need anything higher education. I'm on a wave right now and I just can't get carried away with all this bullshit. If you work and study at the same time, you are unlikely to succeed in anything. ...In general, I don’t understand why it is needed.”
Don't be like Vanya. Go study!
Face had a huge number of girls
But you can’t say that :) What’s even stranger is that this happened before his popularity. Just think about it, in his 20s he dated more than a hundred different girls! In an interview, he honestly admitted that when he reached 100, he got a “Playboy” tattoo and stopped counting. And that is not all! Face said that he never uses protection.
“I still don’t know how to use these things... Haha, just kidding. But I really don’t understand them much.”
But you and I are smart girls and we understand what terrible consequences this can lead to.
Face believes that planning is for old people
The rapper never plans his life; everything happens spontaneously. Of course, this lifestyle has its own thrill, but for how long? “I generally hate planning anything and I think that this kind of life is for old people. I love thrash and the elusiveness of the moment." It’s also funny that he immediately said that he plans to marry Maryana Ro (if you didn’t know, they
When three devices come out at once, and these are the iPhone 8, iPhone 8 Plus and iPhone X, real confusion begins regarding the features. Many users begin to get lost as to what and where.
There is a lot of information everywhere about the Face ID function. Is it available on the new iPhone 8 and iPhone 8 Plus? a large number of they cannot understand people and so that there are no more incomprehensible situations, today we will clarify this point once and for all.
How to enable Face ID on iPhone 8?
To understand this issue, it is enough to understand what Face ID is. If anyone else doesn't know, this is a face scanner and is used to unlock the phone, payment system Apple Pay and in general everything else that Touch ID was used for.
The device can only have one security system, either Face ID or Touch ID. As you know, the iPhone X does not have a Home button, because it is called frameless and the presence of any buttons on the front is simply unacceptable.
Therefore, to get out of this situation, a face scanner was invented so that the user did not have to use his fingerprints and there were no additional inserts on the back.
IPhone 8 and iPhone 7 are not too different from each other and, in fact, all the differences can simply be counted on your fingers. And if we talk about the Touch ID fingerprint scanner, it is still present and functions well.
So, to answer your question, I can say that there is simply no Face ID on the iPhone 8. This means that Animoji is also missing, because it uses a face scanner.
There is no need to be upset about this, because both technologies are still quite raw and we will only be able to see their full potential next year, with the release of the next generation of iPhones.
