Compared with biometric unlocking, Sense ID is an important development trend in the field of mobile phone unlocking in the future.

Since 2013, Apple has introduced biometric unlocking on mobile phones. This technology has quickly become popular, and mobile phones from all walks of life have imitated them. It can be said that it is everywhere and everywhere.

In 2017, Apple X introduced a new biometric unlocking technology: Face ID. Face recognition technology is the only unlock mode in Apple X, and it is clear that Apple is ready to get rid of fingerprint recognition that has been proud of for many years. But for now, Apple X's Face ID is not mimicked and applied by major manufacturers like fingerprint unlocking, which is puzzling. It is reasonable to say that picking up the phone and putting it in front of it, the phone is unlocked, as convenient as looking in the mirror. Why is there no manufacturer to spread it?

A large part of the reason is technical. Face ID is not just a problem with the recognizer. It must be combined with 3D structured light technology to start the implementation. As for the 3D structured light technology, only a few manufacturers are currently in control. Another is to collect data on facial features and create 3D model saves. If this is not possible, the unlocking effect will be poor, and the more fatal is that the safety factor is greatly reduced. Therefore, under the premise of not getting the true biography, the mass manufacturers will not easily try. Therefore, it is very difficult to promote the popularization, and the other one is the speed of unlocking. Many Apple X users have responded that Face ID recognition speed is much slower than traditional fingerprint recognition. In this speed-seeking environment, the slow speed of unlocking is also a fatal flaw.

Iris recognition is a new way of biometric identification introduced by Samsung when it released S8 last year. The specific working mode is a bit like facial recognition. Sensing the distance and scanning the iris data of the human eye to compare the database to unlock. The only difference is that Apple X collects data from people's faces, while Samsung collects data from people's eyes. The data in these 2 are unique to the human body, so the safety factor is not bad. Similarly, the unlocking speed is slower than the traditional fingerprint unlocking. Fortunately, Samsung retains the traditional fingerprint unlock while adding iris recognition. So, Samsung's iris unlock is just a gimmick? Iris unlocking is the same as Apple X's facial recognition. It has not been promoted because of technology and other things!

Since the fingerprint was unlocked in 2013, this solution has been adopted by the world's mobile phone manufacturers, which can be said to be even better. China has developed a new unlocking method that is different from traditional fingerprint unlocking: (optical) screen fingerprint unlocking. Launched by the VIVO X20 plus, the limelight is no less than the 5S that Apple released. The Xiaomi 8 exploration version just released this year also uses this unlocking method. For now, the mode of fingerprint unlocking on the screen is still very popular, mainly a word: cool! With a finger on the screen without any holes, you can unlock it with a little bit of your finger. However, since the screen fingerprint unlocking has just arisen, some defects cannot be avoided, and 3D structured light must be applied. It is necessary to use an OLED display screen and various conditions, so development is hindered. Some netizens compared the speed of unlocking the screen and unlocking the traditional fingerprint, or the traditional fingerprint unlocking fast! Then the fingerprint unlock on the screen ends like this?

No, there is now an upgraded version of fingerprint unlocking: Sense ID, also called fingerprint unlocking under the ultrasound screen. More playable than the normal screen fingerprint unlocking, the range of fingerprint unlocking under the ultrasonic screen is not a specified point, but a specified area, that is, in this area, wherever you press at will effective. Moreover, the recognition rate is higher, the penetration is stronger, and the speed of unlocking is greatly increased. Some foreign media broke the news, Apple and Samsung's new flagship machine will apply this new unlocking solution. It can be seen that the advantage of fingerprint unlocking under the ultrasonic screen is large.

Therefore, Xiao Bian believes that Sense ID will be an important development trend in the field of mobile phone unlocking in the next few years. Compared with face recognition and iris recognition, it has great advantages, mainly reflected in the fact that fingerprint data is small and easy to collect. Second, the hand is the most flexible organ of the person. Fingerprint unlocking is also the most convenient and quickest way for people. Third, relative to facial recognition and iris recognition, fingerprint unlocking does not require the creation of a 3D model, which may be much easier in technology.
