Underwater unlock actually failed | After reading these challenges also buy kidney X?

Faced with the 10th anniversary of the iPhone this year, Apple released a full-screen design of the iPhone X has aroused widespread media attention, its face recognition technology Face ID become more popular hot topic now iPhone X has been on sale, People are questioning its effectiveness, safety and creativity, and in order to find answers to these questions, our team at ZOL challenged Face ID, which claims to be one in a million mistakes.

Face ID in the end can fully protect the user's safety, and in some harsh environments can still be used normally? With this question, the editor made 12 on iPhone X face recognition violence test, take a look at iPhone X In these conditions, but also can not unlock it yet.

Face ID working principle analysis:

Earlier, Apple officially released a white paper on Face ID detailing how Face ID works: Face ID uses the TrueDepth Camera to project 30,000 invisible points to capture user face data and create Facial depth map; the same time, through the infrared camera to capture facial infrared images.

At the same time, the A11 release of the chip's separate neural engine (Neural Engine), the user's facial data processing, and registration of user facial data compared to the following today's 12 tests.

1, unlock underwater

The initial test is interesting, since iPhone X has the ability to drain dust on IP67 and test whether it works in water.

The result is eye-popping, iPhone X is not unlocked after three tests, the conclusion is iPhone X in the water can not be unlocked.

2, speed unlock

Is it fluent to unlock iPhone X while running or moving? Again we tested.

The results showed that iPhone X could not be quickly unlocked when swiftly moving the arm or with a large range of motion, which required some 'pause' to recognize the time, although this was a short time.

3, cats / dogs to unlock

Recent Dog Face Entries and Unlocking iPhone X Successful videos are widely circulated on the Internet, and although the dog has not been well matched, the dog successfully unlocked the phone after two recorded faces. : Even dogs have iPhone X. In order to test the video is true, we use a cat Face ID input unlock to see if it works.

Test Results: While recording the face of a cat, the iPhone X can record the facial contour of the cat. However, the unlocking can not be successfully unlocked. Therefore, for the moment, the iPhone X does not allow facial recognition Way to unlock the phone.

4, many people to unlock

Continue to test the performance of facial unlocking on iPhone X. Multi-faceted Multi-face When entering the iPhone X screen, it is inevitable that its infrared lens and The original deep interference lens, take a look test:

When the three immigrants to enter the unlock, when the 'protagonist' stood in the middle of the three, there is no significant difference between the unlock process and single unlock, the unlock speed is also more normal.

When the object is recognized at the edge of the trio, the lens does not directly shoot the 'protagonist', iPhone X appeared insensitive phenomenon, iPhone X and not the first time to identify the owner, sometimes slow, sometimes The result was a 50% success rate (10 tests and 5 unlocks), which also means that users with iPhone X try to align their faces with the camera as they unlock the phone.

5, foil unlock

Foil is the most loving young people bought a new machine to do the first thing, since the iPhone X is a bangs shape, then it's cell phone foil must also be bangs, the sensor position must be exposed? We will be iPhone X screen at the top of the sensor paste a thin layer of plastic film to test.

The results are very regrettable, the failure to unlock.Applying a thin plastic film will affect the identification of iPhone X. Interestingly, with the naked eye can not see the infrared flash, when shooting with the camera came out, mainly because of the camera Photosensitive devices can receive spectral range stronger than the human eye, so you can shine on the infrared.

6, stains to unlock

Tainted to unlock the test session, using a color and more viscous milk for testing.

And foil test has the same characteristics, covering the sensor can not be unlocked, without cover can be unlocked.

7, double learning to unlock

Face ID, also known as One in a Millionth, a 10-year-old boy who unlocked her mother's iPhone X with her own face.

The man named Malik recorded a video and posted it online: Mom, Sana Sherwani, recorded her facial features into her cell phone and her son, Ammar Malik, unlocked the phone and, according to the family, Ammar had been able to unlock his mother's iPhone X, maybe even his dad, but that seems impossible to reproduce.

Andy Greenberg of Wired Magazine wanted to verify the process, and suggested that Sherwani re-record Face ID and unlock his son to see what happened. The result was a son's failure to unlock. Interestingly, a few hours later, Under the indoor lighting conditions, Ammar's face can unlock the phone again.

The reason is not hard to understand because iPhone X's Face ID will continue to learn to adjust, enter the mother's face, the son constantly unlock with the password to enter, resulting in a second face information is mixed with the first face of information , The result is that both faces can be unlocked, which can be very magical, but it also shows that iPhone X is not absolutely safe.

8, one eye to unlock

Open one eye, the other eye closed, test whether the iPhone X can identify its owner.

The result is that the iPhone X recognizes users who only have one eye open, and the reason is well understood that the iPhone X is unlocked by recognizing the contours and structures of the user's face and is not a way to identify images like a QR code .

9, across the glass

Since the phone can not be blocked at close range to unlock, then whether through the glass iPhone X unlock it?

As a result, the glass can not stop the pace of unlocking the iPhone X. This is not only a reflection, since the glass can, then the plastic film to block the iPhone X can not be unlocked perhaps the current recognition in the field of Apple, there is still no place to overcome the technology.

10, super dark light

Unlocking in super-dim light is theoretically not too much of an issue for the iPhone X equipped with infrared lenses. How Infrared Light Simply Speaks Infrared Technology in the Dark: All objects that have temperature, not absolute zero, can radiate The naked eye can not see the infrared. Infrared radiation directly onto the object is the result of heat. In short, the infrared camera with the original deep camera allows iPhone X in the dark can also be easily unlocked.

Unlocked in the dark light environment, iPhone X did not let us down, you can clearly feel the unlock speed and no difference during the day.

11, light to unlock

Stay away from home, it is inevitable encounter the dazzling hot sun, we guess the strength of the light will not interfere with the Face ID unlock it?

First, we put the fill light up to 100 watts and tested three times against the face and found that the iPhone X was unaffected.

We put 100 watts of fill light direct iPhone X, three times the test found iPhone X still did not receive too much influence, unlock speed smoothly.

12, long-distance unlock

iPhone X maximum unlock distance is what, we also tested.

Using and tapping the tape and moving the iPhone X in parallel, the results of the three tests were both 60 cm, meaning the farthest unlocking distance for the iPhone X was 60 cm. The human arm was about 70 cm long, and lifting the phone had one Arm curving motion, This result can be said that does not affect the normal use of most people.

Write last:

Now, all 12 tests have ended.Although these 12 tests include the mainstream opinion test, as well as non-mainstream opinion test, but it also reflects some of the features of the iPhone X: In general, the best use of Face ID distance Is 20-50 cm. Officially said it will automatically adapt to the user's appearance changes, such as make-up or grow a beard .If the user's appearance there have been significant changes, such as shaving a beard, Face ID will require the first password Verify the identity, and then update the facial data.Moreover, Apple officials said Face ID is only 1 / 1,000,000 unlocked by others, and let the iPhone X continue to learn the successful double unlock test results, which makes Apple's official rhetoric Some paradoxes, Face IDs may have a long way to go, perhaps at the 'how to learn' level.

Although Face ID is not perfect, from its body, we also see the development trend of the future mobile phone industry, the infrared camera + original deep camera face unlock way, is step by step to replace the fingerprint to unlock.
