At the time were all a surprise but today fingerprint readers are one of the most common features on smartphones. 5s iPhone was not the first to port it, of course, but it certainly contributed to fix a trend at your arrival. The security of smartphones had since then with a new ally: the biometric identification.
Regarding this, we are used to make optical. Fingerprint readers carry cameras make a screenshot of your finger and, through recognition patterns, determine if we are or not. But earlier this year was a new technology that is now installed on my 5s Xiaomi. Ultrasonic fingerprint readers, are devices with real advantages or simply a marketing strategy?
Confirmed, it’s Sense ID
While fingerprint sensor rear of my Xiaomi 5s Plus was quickly confirmed by the manufacturer of the sensor on Twitter, Fingerprint Cards, the model with the standard ultrasound kept a little more suspense until the own Xiaomi published the official tab. Finally it’s Sense ID, Reader submitted earlier this year by Qualcomm and we have already seen in some terminal as LeEco you Max Pro.
On January 5 of this same 2016, Qualcomm made public its new fingerprint, Sense ID detection system. The new system was something else the cameras we’ve seen so far. The detection was not visual but acoustic, a system of ultrasound that created a three-dimensional representation of the object that had front and allowing one greater degree of security, although that will see it later.
Sense ID has not reached for the first time in the my 5s Xiaomi, as we mentioned at the beginning. Xiaomi device can be, however, the main driver of Qualcomm technology it is a very popular manufacturer and with an excellent reputation both at home and abroad. Will we see more Ultrasonic sensors now? Probably, but before we see its advantages.
It is safer
He has been said on many occasions that the biometric sensors provide an extra point of safety to our devices, not in vain carried decades using technological non-smartphone devices. With everything, they are vulnerable and the most fond computer security have already found ways to violate the system and pass through them.
We don’t talk about Ethan Hunt capturing footprints with a plastic sheet and some glue, but this system has proven to be able to fool a fingerprint reader. We are talking about skipping the reader using simple photocopies of our fingerprint, current fingerprint sensors used a photograph and, therefore, to detect our footprint in two dimensions. Therefore it is easy to make an image through our own finger and, voila, unlock the phone.
Ultrasonic fingerprint reader from Qualcomm is a three-dimensional image so it is able to discriminate between an image and an object in relief. Allows you to sense ID capture the smallest imperfections of our fingerprint and thus ensure that we are those who try to unlock the phone with margin of error much less than the photo.
It is more efficient
Another great advantage of a ultrasonic fingerprint reader is its efficiency against the photographic. The manufacturers themselves warn of possible errors in the detection footprint if we dirty or wet, toe that the combination of a submersible smartphone and a fingerprint reader is not the best that can offer today. In the end, he plays go to the pin to make usable phone.
Sense ID detects finger in three dimensions and therefore no matter what color is your finger, so it We can have it stained at the time of the release. It also influences is wet because water refracts the image of photography and distorts it, but it has no effect on ultrasonic mapping which, according to the own Qualcomm, should be able to avoid all the objects that are not purely our footprint.
Much better integrated into the smartphone
The differences between a photo reader and other ultrasonic appear stronger if it fits in the integration of your own player to the smartphone. We are accustomed to seeing that the fingerprint reader excels own Smartphone, sometimes in a more pronounced way and in others it is more covert. Something which, on the other hand, does not help too I be it with your finger to unlock your phone, as it happens in the Vodafone Smart Platinum 7.
Position the reader on the surface is a requirement of readers today because they need to “see” your finger to photograph it. Ultrasonic readers have the ability to pass through opaque surfaces and similarly that Xiaomi has hidden his behind a transparent glass, could have it set after the terminal housing, marking his position with a simple screen printing on metal.
Thus, while Xiaomi has the reader in the front bass, also could have it hidden behind the screen itself. Do not confuse this technology which is rumored for the Microsoft Surface Phone, which is supposed to be able to detect your finger anywhere on the screen. Ultrasonic sensor still need a transmitter and a receiver, so its size is limited and must be located at a specific point to turn to unlock the device.
Another possibility, the fact that the finger should not necessarily touch the fingerprint reader, as we have already deducted to talking that I can hide it behind other materials is added. So, Why not imagine an aerial detection in the future? It will certainly be viable and would only have to graduate these ultrasonic power.
It is not marketing, it is the future
View all of these capabilities of the new Qualcomm Sense ID fingerprint reader, we can realize that We should not take in attending a technology replacement by another. The small current cameras must go giving way to ultrasounds. More efficient, safer and faster, as well as allowing changes in the design of the own smartphone.
Qualcomm came earlier year with Sense ID and is already noted, let’s hope that soon more marks are pointing to this new type of release, and continuing flows of more systems added as Note 7-Galaxy-iris reader. Our phones went from making calls to contain all our data inside, all the security measures we take to protect it will be few.
