[Trafodaeth]List of four mobile phone biometrics, which unlocking method do you like the most? – Mobile phone brand news | ePrice

Now people’s mobile phones store more and more data related to personal privacy, covering large amounts of information such as finances, identity, and images. To enable users to use the device securely, the user authentication method has also been upgraded. People can no longer be like the age of feature phones, where everyone’s cell phone is unlocked and others can borrow it to watch at will.

Today, face and under-screen fingerprint unlocking is the solution adopted by most models, and it’s also the most used unlocking method for you and me. However, whether it’s face or under-screen fingerprint unlocking, there are still some flaws. Today, let’s take stock of the biometric methods that have appeared on mobile phones in the past and their respective advantages and disadvantages.

Unlock an entity’s fingerprint

As early as the 1990s, Siemens launched the mobile phone fingerprint recognition and unlock function on mobile phones. For fingerprint recognition on smart phones, the initial fingerprint sensing area is mainly designed on the back of the phone, and many inconveniences are still used. Therefore, it later evolved into a “front unlock pie” designed on the front like the iPhone and early Samsung Galaxy series phones and integrated with the Home button, and a “side unlock pie” designed on the side like SONY phone and integrated with the power button.” Two factions. In the pursuit of a high screen-to-body ratio for mobile phones, “front unlock” mobile phones have almost disappeared.

Fingerprint unlock under the screen

In 2017, vivo introduced the fingerprint recognition and unlock under the screen for the first time on the OLED screen of the mobile phone. The fast, convenient design without sacrificing the screen ratio was adopted by most mobile phone manufacturers except Apple, which was promoting Face ID at the time. In addition to optical screen fingerprint recognition, Qualcomm also launched the 3D Sonic Sensor technology based on ultrasonic waves, emphasizing that 3D depth information from fingerprint grooves can be detected through ultrasonic waves, so it has higher security.

The advantage of under-screen fingerprint unlocking is that it is integrated with the screen, so there will be a better full-screen experience; however, the under-screen fingerprint unlock recognition speed will be slightly slower than that of the physical fingerprint reader. , especially the ultrasonic fingerprint reader, which is more vulnerable to the interference of the screen protector, so you have to pay more attention when buying the protector.

unlock iris

Samsung adopted the iris recognition unlocking solution on the earlier Galaxy flagship smartphones. Compared to fingerprint unlocking, iris unlocking is more secure and accurate; but the disadvantages are also very obvious, such as high cost, actions It is cumbersome, etc. the phone needs to turn on the screen first, and then place the human eye on the designated area to complete the unlocking. The recognition speed is a little slower than fingerprints and faces.

With the Galaxy S10 adopting the fingerprint unlock function under the screen, Samsung also announced to say goodbye to the iris unlock function; cause discussion.

face unlock

Although facial recognition unlocking has been used on mobile phones for many years, it has never become mainstream, and 2D facial recognition technology also has the problem of poor security. It was not until 2017 with the release of the iPhone X that Apple boldly used the Face ID 3D face unlocking technology on the iPhone for mobile phone unlocking and mobile payment, which allowed facial recognition unlocking to enter the mainstream market .

However, not only does 3D face unlocking require the sacrifice of screen space, but the configuration of 3D structured light face recognition components will also increase the cost of mobile phones. Especially with the progress of the epidemic, people generally need to wear masks, which has caused a lot of inconvenience when using them. Therefore, most Android models also use fingerprint recognition to unlock.
