In the fall of 2017, Apple made it clear that the era of fingerprint identification of users has passed and it is time to move on. As an alternative, in Cupertino, they chose face recognition technology, which, according to the company, is almost impossible to deceive. But, as it turned out, Apple could continue to exploit the second-generation Touch ID interface, which, regardless of age, turned out to be a more convenient solution for unlocking than what competing companies offer.
In autumn 2017, Apple clearly made it clear that the era of user identification by fingerprints has already passed and it is time to move on. As an alternative, in Cupertino, they chose face recognition technology, which, according to the company, is almost impossible to deceive. But as it turned out, Apple could continue to exploit the second-generation Touch ID interface, which, regardless of age, turned out to be a more convenient solution for unlocking than what the competing companies offer.
Journalist of the edition PCWorld Michael Simon decided to check how the fingerprint scanners have changed, and conducted an independent experiment. To do this, he took the iPhone 6s, Galaxy S9, Galaxy S10 and OnePlus 6T. Such heterogeneity of the subjects is explained by different technologies of fingerprinting: the first two smartphones are equipped with physical scanners located on the case, the third – with ultrasound technology, which is considered the most protected of all, and the fourth – simplified optical.
h2 Smartphone with the best fingerprint scanner
Since it was quite difficult to check the level of protection provided by scanners in the field, and, as practice shows, it was completely unnecessary, it was decided to test the recognition rate from signet. And in order to make the experiment as honest as possible, it was performed in three usage scenarios.
During the first test, Simon checked the unlock speed with repeated scanning. To do this, the author activated the smartphone screen, scanned a finger, and then blocked the smartphone and repeated the procedure again. Thus, each device suffered 10 unlocks, but each of them took a different amount of time. The iPhone 6s performed best in 15 seconds. In second place – OnePlus 6T, 17 seconds. The third is the Galaxy S10, 19 seconds. On the fourth – Galaxy S9, 20 seconds.
The second test was designed to determine the effectiveness of the scanners in situations where the user’s hands are soiled. As substances designed to confuse the scanner, were selected water, soap solution and powdered sugar, each of which Simon dipped his finger before scanning. In this test, the Galaxy S10 turned out to be the best, whose ultrasound scanner was the only one that managed to break through the water and the soap solution.
The final test showed which scanner is most convenient to use in everyday life, taking a smartphone out of his pocket and putting to him a finger to unlock. The iPhone also emerged victorious from this test. It took him an average of 1.5 seconds to unlock. Optical scanner OnePlus 6T proved to be a little worse, removing the lock in 2 seconds. Samsung’s flagship smartphones were the worst of all: the Galaxy S9 scanner opened access to the contents of the device in 3 seconds, while the Galax S10 ultrasound module – already for 4.
The third test was the most revealing, because that is how we use our smartphones 99% of the time, the four-year-old iPhone 6s scanner proved to be more than worthy. Of course, sometimes it happens that it is very important to remove the lock from the smartphone when the hands are not completely clean, but such situations occur extremely rarely. Therefore, the question of why Apple made a bet on face recognition technology without becoming embedded fingerprint under the display of the iPhone, can be considered closed.
