Fingerprint, Face Unlock and PIN: Which is the best?



If you know the Hierarchy of Needs of Maslow, you know that protection is one of the basic needs that we humans need to fulfill. And that goes for our devices in both directions. They must always be secured, which is why we have several choices to secure our smartphones — from the good old pin and pattern to the more sophisticated fingerprint sensor scanner.

This raises the question: which of the most reliable and safe biometric security options?


PIN


PINs consist of numbers which vary in length depending on the phone you are using. You definitely can't get rid of it, because you will probably spend hours and hours trying to unlock your computer if you mess up and forget your password.


PATTERN


Unlocking the pattern is a safety mechanism found only on Android phones. If you want, you can use it in conjunction with the PIN, but it is a decent security device by itself. You can only try it a number of times until it locks you out for a couple of seconds.

But, as always, the device must delete user data through some incorrect attempts. One of the problems this method can cause is that your finger or thumb can leave patterns or a trail on your displays that make this method less functional. Make sure that the presentation is free of smudge

PASSWORD


Many users consider this as the easiest way to unlock the computer by using a combination of numbers and letters. However, if you lost your password, retrieving the password can be as hard or harder as the PIN.


FACIAL REGONACION


Before Apple's FaceID, a facial unlock feature on Android phones was already discovered. It was first seen on Android 4 (Ice Cream Sandwich), but it was not the best and most reliable feature at the time. It used only your front camera and 2D face algorithms. So a simple picture of you is necessary to unlock your phone. But over time, with the introduction of the Microsoft Lumia 950, which used Iris Scanning technology, face unlock gradually improved. It scans the iris with an infraround light beam. Infrared light works better because it reveals the iris pattern even when the light is dim.



Instead, with the iPhone X, Apple introduced FaceID. It is much more safe as it uses 3D face scanning and a variety of sensors including infrarot light, flood lights and dot light to map the entire face of the consumer.






Fingerprint scanner: Capacitive and In-display
Capacitive Scanner


This scanner is currently the most popular model in smartphones and is much more accurate in terms of safety than modern optical displays. The idea behind this is that rather than recording an image of your fingerprint, the capacitive scanners use small condenser circuits for data collection. It would be quite difficult to fool this one without the hardware or software problem of the device


In-display Fingerprint Scanner: Optical and Ultrasonic


OPTICAL SCANNER

This scanner lights up a 2D representation of your finger and records it. As such. As such. The downside is that, compared to the ultrasonic scanner, it is theoretically easier to fool this sort of sensor.

ULTRASONIC SCANNER

In contrast to the optical scanner, your fingerprint is not only given a 2D picture by ultrasonic scanners. This gives the fingerprint a 3D feeling. It's like fingerprint scanners ' FaceID. It's a lot more reliable and precise. Then Qualcomm announced a 3D Sonic Sensor, the 3D Sonic Max, second generation to address issues identified in the original. The company has promised that the new version will be 17 times larger and more robust.

Let us now return to our first question: what is the most secure and healthy of these biometric securities?

Honestly, we still recommend your password because it is much safer, but less convenient than unlocking face and fingerprint. Indeed, all complementary or secondary protection measures include an iris scanner and facial recognition. As the technology behind them improves, they're not good enough to be the only way to protect your phone. With these methods, you still need to register as your first option for a PIN, pattern or password.

You can always count on more traditional options, such as the PIN, pattern or password because a second layer of protection is not required for them.

So you guys, how about you? Which of these safety methods are most reliable and secure for you? Only leave a comment below.
