With the challenge of maintaining reliability and quickly authenticating the real user, manufacturers continue to dedicate themselves to new types of mobile biometrics.
At first, the users They could only trust one numeric password to encrypt your banking records, credit card numbers, private messages and other personal information. Over time, the ways to enter the phone have been advancing and have come to recognize the physical characteristics of the individual.
Next, we will talk to you about this sophisticated technology.

Face recognition
Like the fingerprint reader, Apple Lossless Audio CODEC (ALAC), was a precursor of facial recognition. The software maps facial features known as nodal features to authenticate the person. Face ID It is the best and most stable unlocking model iPhone and it is the fastest in the iPhone 11 Pro.
In addition, it is very easy to use, since you only have to look at the front camera.
Iris Reader
The Galaxy S8 proposed an important way of unlocking: iris detection. Here, the device maps the peculiar features that make up the iris of the human eye (like the characteristics of a robotic eye) and then authenticates the user.
It is a very successful approach that massively prevents popular attempts to access another person's mobile phone. However, experienced consumers have devised strategies to recreate the system's proprietary features and deceive the viewer. Besides, iris identification was slower than the detection of fingerprints.
The sensor on the back
Due to the new magnification pattern of screens, the fingerprint reader began to move towards the back of the device. As before the sensor was on the front, it took up the space below the screen, which took up much of the bottom edge, an area that could be used for the screen.
Little by little, the reader It decreased until it died completely, and then moved to the back. In fact, there are mobile phones on the sides that feature it.
Being hidden, the sensor gave a little more user protection, so people could no longer clearly see which finger activated the machine. Operation was slower, however, than when placed on the front, since the user could not see the sensor.
The Redmi Note 7 It is one of the devices that focuses this technology on the rear, but it is also present on the Galaxy A20 and A30.
The sensor integrated into the screen
Although the biometric reader It was no longer part of the front of the device, the user continued to be bothered by the fact that he had to touch the back with his fingers while maneuvering the phone to avoid falling. However, the idea of advancing the sensor was inconceivable, since manufacturers had already taken advantage of the area to stretch the screen. The option, then, was to put the reader integrated into the screen itself.
Innovation brought technology to the level of ultrasound, producing more protection and rhythm through digital scanning and formulating a 3D model simulated. However, it was easily circumvented with a simple detail: since most of the panels are glass, the human digital leaves a heat mark, so it could be cloned.
