Galaxy S8 isn’t just going to be fast when you talk about raw speed, but also Samsung is intending on implementing a new security feature that’s going to be much faster than ultrasonic fingerprint recognition. By now you may have heard that Samsung is planning to get rid of the home button, and perhaps decrease the bezels on the Galaxy S8 but the obvious question was “What happens to the fingerprint scanner?”
I, for one, believed Samsung would probably use Qualcomm’s SenseID which uses ultrasonics to detect fingerprints more accurately and can be implemented right onto the display. Turns out, Samsung is probably looking at something even faster and accurate.
Optical fingerprint recognition
Sam Mobile reports that the Samsung Galaxy S8 will feature an optical fingerprint scanner housed under the seamless glass of its front display. The site claims that optical recognition is both faster and more accurate than the kind of ultrasonic fingerprint scanning made possible by Qualcomm’s Sense ID. Faster, probably but accuracy I’m not so sure of.
So far there has not been any smartphone to utilize optical fingerprint recognition technology, meaning that Samsung could be the first. But wait a minute, there’s a reason why no one else has implemented it yet.
Optical fingerprint scanners are stupidly easy to fool and are the oldest method of capturing and comparing fingerprints. As the name suggests, this technique relies on capturing an optical image, essentially a photograph, and using algorithms to detect unique patterns on the surface, such as ridges or unique marks, by analysing the lightest and darkest areas of the image.
As the technology is only capturing a 2D picture, prosthetics and even other pictures of good enough quality can be used to fool this particular design. You may have seen this happen in movies so many times. This type of scanner really isn’t secure enough to trust your most sensitive details to.
Capacitive sensors like Apple’s TouchID or Ultrasonic scanners like SenseID are far superior in terms of security and Samsung also has Samsung Pay involved in the mix so for Samsung users, who do use Samsung Pay, this can turn out to be a disaster. And Samsung can’t afford that when Samsung Pay’s security flaw recently made a few headlines, not to forget the Galaxy Note 7.
Even if we were to believe that Samsung is working on upgrading this old technology, it would need to be a significant advancement over even the advanced kind of electro-optical scanner that can distinguish between a live finger and an image of a finger. And why would Samsung spend money, time and resources in upgrading an old technology rather than adopting a newer one, especially one that fits the bill here (SenseID)? Beats me.
So I’d suggest don’t hold your hopes up, and if Samsung does indeed go this route, it will be interesting to see how they do it. What do you think?
