Samsung Note 7 will carry iris recognition technology
China Internet of Things News Beijing July 7 news, according to technology site PhoneArena reported, speaking of the term iris recognition, we are not unfamiliar, because this technology has long been the oldest of many spy movies. In addition, all kinds of major examinations now require us to input iris information, and some units even use this type of identification system for checking in and out of get off work.
Soon, the technology will appear in the mainstream smart phones, allegedly in the second half of this year's Samsung flagship Galaxy Note 7 will be equipped with iris recognition technology. So how does this seemingly spy-full technology come about? What is the difference between it and our common security solutions (such as fingerprinting)?
How does iris recognition work?
First of all, we come to popular science knowledge. In addition to the common brown, blue pupil, the world there are green, amber and silver pupil. In addition, people who have the same color pupil (Persian cat eyes) also exist, but they account for only about 1% of the world's population.
The iris is the material that determines the color of our pupils. If you look closely at people's attention, you will find that the surface has complex wavy lines, and these lines are your fingerprints on the iris, iris scanners rely on them to identify you. Like fingerprints, these lines are very complex and their formation is random. Therefore, everyone's eyes are unique, even your left and right eye irises are different.
Is iris scanner is taking a picture of the human eye, and then compare with the pictures in their database? Non-non-also. In fact, the entire recognition process starts with the irradiation of the near-infrared. This invisible light "lights" the lines on the iris so the camera can snap a clearer iris photo. In addition, this bunch of near-IR also made iris recognition work in the dark as possible.
If you are myopia do not worry, ordinary lenses and contact lenses will not block this bunch of near infrared (except for color contact lenses). Once the iris scanner has captured your iris data, it automatically translates it into the corresponding code, which in the future will become a reference in recognition.
Is there any difference between Note 7's iris recognition?
The principle of iris recognition in Note 7 is similar to that described above. The sensor that appears in front of the fuselage in the rendered image may be an iris camera.
In this case, why should we add another sensor? Common front camera iris can not complete the task of identification? In fact, the reason is very simple, ordinary front camera is not sensitive enough, and it can not issue the near-infrared mentioned above. In a normal camera, the infrared light is filtered out completely by the filter because it can interfere with taking pictures. In addition, in order to clearer access to the user's eye information, the new sensor focal lengths longer, which determines it simply can not afford ordinary wide-angle Selfie task.
What is the difference between it and retinal recognition?
First of all, we need to clarify two concepts: Generally speaking, the iris recognition is actually different from the retinal recognition. Although they are from the human eye, but the scan is actually a different part.
Because the retina is deep in the eye, iris recognition is more user-friendly and faster on mobile devices.
Iris recognition in the end what are the advantages?
Many people will certainly say that, since now even thousands of machines are used fingerprint recognition, do we still need iris ID? What is it in the end?
In fact, iris recognition is more secure than fingerprint recognition.
Although fingerprinting has a high penetration rate, such biometrics can easily be exploited by criminals (easy-to-copy), after all, we always leave fingerprints inadvertently. In addition, the use of fingerprinting users know that every summer when the fingerprint reader on the phone face hot and humid fingers will be a little powerless. However, these problems do not bother iris recognition at all because it is very difficult to copy the high-resolution iris data of others and the eyes are not sweaty like fingers.
However, we do not expect too much iris recognition on Note 7. This new technology certainly has its own uniqueness, but it certainly has a lot more user experience than the more mature fingerprinting. Previously, Lumia 950 had also tried such a technology, but slow recognition speed and rigid recognition distance made it a "cool tasteless feature." If Samsung can not significantly enhance the use of iris recognition experience, I am afraid this feature can only live in the configuration list.
Of course, science and technology day by day, Samsung dare to iris recognition on behalf of them have enough strength, if the experience is good, the technology is bound to lead the industry's new development trend.
