An article to understand what is iris recognition
Acuity Market Intelligence, the US think tank, has published a report on "The Future of Biometrics". The report shows that iris recognition technology will rapidly spread in the next 10-15 years, accounting for 16% of the global biometrics market, and total iris recognition products. The output value will also reach 3.5 billion US dollars. After all, there is no need to say that outside the smartphone, the rise of the entire IOT industry in the future can be regarded as the cornerstone of the popularization of iris technology. You know, when the era of Internet of Everything comes, data security is taking place and people are moving. I am looking forward to a way to interact with machines more securely.
Thanks to Hollywood, the following scenes have long been regarded as part of the future: a Boss-level character looks calmly or flustered into the mysterious department of the lab, and he only needs to "look at" the screen to come and go. In fact, iris recognition is not a nascent thing. The theoretical cognition based on iris scanning to identify identity can be traced back to the 1930s, and gradually commercialized in the 1990s. Now it has also been applied in finance, government, airports and The military and other places that look like "mysterious departments" in reality. But as you know, the underlying driving force of human history is always technology and the business that spreads technology across a wide range. Following the similar steps of disruptive technologies such as computers, the Internet, and smart phones, iris recognition is now taking specific areas. Promoted to the general consumer group. The most intuitive example is of course the Samsung Galaxy Note7, which is the first time that iris recognition technology has been added to the true mainstream flagship smartphone.
In the eyes of many people, considering the control and appeal of Samsung in the mobile phone industry chain, the urgency of iris recognition is different from the niche models such as Fujitsu ARROWS NX F-04G and Microsoft Lumia 950XL last year (such as recognition time). Long), Samsung's entry is expected to play a certain driving force - it is reported that Samsung's participation even makes the stocks related to iris recognition stocks once red. The maturity of technology is of course another aspect. Throughout the ages, human beings have long been eager to "accurately identify themselves" - and there is reason to believe that it is increasingly important to safely inform the machine "who am I" in the future.
In this case, at least it seems that iris recognition can do more.
Your only
In general, in all conventional biometrics (including fingerprints, faces, irises, sounds, palm prints, etc.), due to the accuracy, anti-counterfeiting, uniqueness, and stability of the iris itself, mainstream academics generally consider the iris to be Fingerprint or facial recognition is more "advanced" identification method. It should be known that compared with 0.8% of fingerprints, 2% of the face's false positive rate, iris recognition as low as one millionth of the misrecognition rate seems to have almost no Bewildering.
What is the iris? The structure of the human eye consists of three parts: the sclera, the iris and the pupil. The iris is the annular part between the other, belonging to the middle layer of the eyeball, which is responsible for automatically adjusting the size of the pupil to adapt to different lighting environments. The subtleties such as crossed filaments, spots and stripes constitute a large number of unique information features of the iris, and therefore have some inherent non-reproducibility (by the way, the uniqueness of the iris also exists in the same egg In the twins, the latter has a very high degree of DNA information overlap, and its complexity far exceeds the fingerprint recognition popular in smartphones today. Studies have shown that iris recognition accuracy is 10,000 times that of fingerprint recognition.
It is conceivable that the small dynamic characteristics make the forged iris almost impossible, at least for now, regardless of the photo, the fake eye, or even the contact lens. (Right, when the eyeball is peeled off, the iris will be magnified with the pupil. Losing activity), there is almost no way to deceive the machine's trust in the owner's iris.
The strong stability is another weapon for the iris to be used for biometric identification. After the formation of any part of the fetus, the iris remains unchanged for the rest of its life and is hardly disturbed by the external environment. Under the protection of the eyelids, it is not susceptible to trauma and, more importantly, it seems to be red eye. The common eye intrusion, cataract, glaucoma, trachoma conjunctivitis, and myopia surgery can not affect the iris's own texture. This means that the iris will not be prone to wear when the fingerprint is unlocked, the sensitivity is low, and the skin is wet or damp, which makes the phone unrecognizable.
In addition, I want to say that, compared to the fingerprint, the long-distance non-contact collection in the iris is undoubtedly much healthier.
how to use
It is well understood that iris recognition technology can convert iris information features into password storage.
In the specific implementation path, for Note7, IR LED and iris camera are added on the same side of the front lens. During the recognition process, the front camera assists the iris camera to determine the general outline of the holder, and then via the IR LED. Infrared light source (Iris recognition can not use the most common color visible light sensor, use a separate infrared sensor to ensure that it can be used under dark light), iris camera scans the iris information of the holder through the light source, and then converts the iris information into code , compare with known passwords to finally decide whether to unlock. Generally speaking, compared to the cumbersome fingerprints, the first time you enter the iris is much faster, it only takes a few seconds. When the user tries to unlock the phone with the iris, according to the video demonstration, although it is no more than a fingerprint, it is still quite sensitive. .
Intuitively, the application scene of iris recognition can be extended beyond the screen unlocking. For example, a scene scheme proposed by Note7 is to add a “safe folder†to unlock some applications including photos, photos and notes. Private data or information inside (you know, everyone has some "unspeakable" secrets), so that it is independent of other mobile phone data, only the iris can be opened, it is a double insurance.
In my opinion, this function also largely responds to the industry's concerns about the popularity of iris recognition – in fact, at least at this stage, iris recognition as a technology pioneer and mature fingerprint recognition is not a substitute for Closer to the complement or advancement in different scenes, this is the safe folder of Note7. You can think of it as the second security protection after the fingerprint. In the movie, the mysterious department has to defend the heavy level. ?
Well, in telling the machine "Who am I?", humans have experienced various passwords, digital certificates, hardware KEYs (such as U-Shield) and so on. There is reason to believe that the next scene of identity is largely It will be completed by biometric recognition such as iris. In fact, retrospective history of human-computer interaction, a clear context is: each form of mainstream computing equipment changes, necessarily accompanied by the difficulty of human-computer interaction, and with the improvement of iris and other recognition technologies, the "trust relationship between humans and machines" "It is bound to move to a new chapter.
The future is paved by reality, and "the future has come." In the field of technology, the next decade will eclipse the past decade, and I hope that there will be great credit for biometrics.
