IPhone mask has been unlocked. What technologies are behind this technology?

IPhone launched the mask to unlock under the epidemic situation. It can only be said that this wave of operation is very beautiful. The black technology that masks are unlocked is completely superior to domestic manufacturers.

Before IOS updates the system, users still need to take off their masks for face recognition. However, after updating the system, in the era of national masks, users feel that the IPHONE in their hands is getting more and more fragrant and beautiful, which is very dazzling in front of domestic machines. And the speed of unlocking the mask has not slowed down. It is estimated that other domestic mobile phone manufacturers will follow suit.

Moreover, Apple's mask unlocking technology is payment level, which can not only unlock the mobile phone, but also be used for payment function. Security will not be greatly reduced. In fact, Cook announced that he owned the technology several years ago, but he didn't show the application. At that time, because of the security of payment, he did not launch this technology. At present, Cook dares to launch this technology, which shows that Apple's mastery of mask unlocking technology is complete and there is no need to worry about security issues at all.

Mask unlocking technology is more advanced than 3D face recognition currently on the market. This time, Apple adopted dot matrix projection technology. Although the face is wearing a mask, as long as the projection can identify the details of the face and eyes, this technology can ignore some facial details behind the mask, thus ensuring sufficient safety and application.

Although many Android users have exposed off-screen fingerprint recognition, it is impossible to wear gloves in autumn and winter. In the face of mask unlocking technology, it looks pale and powerless. Especially affected by the epidemic, it is normal to wear masks now, and the unlocking function of IPhone masks has also come, which is another great progress in technology. However, at present, it is necessary for models above 12 to have this function. I think some Android users will change their Apple phones. According to the past practice, it will take several weeks for the new function launched by iOS beta to be officially launched, and users of the official version will not be able to experience this convenient function until years later.
