Mobile Fingerprint Unlock is a screen saver unlocking software that uses your fingerprint data and performs record verification. When you start the software and enter the unlocking interface, you can simply unpack your phone by placing your finger in the scanning area and waiting for a short scan comparison.
Iris recognition
Iris recognition, as the name implies, uses an input instrument to scan our eyes to obtain iris information from the human eye and to create an iris database dedicated to the iris. Similar to the fingerprint information, the iris information generated by our eyes is also unique, so the iris recognition is also without the identification of the second personal identification information.
In the face of many mobile phones equipped with iris recognition function in recent years, the front camera needs to work under the strict and unique technical conditions and cooperate with the infrared light at the same time. After scanning the iris data of the human eye, the speed is extremely high. The matching of the data information is entered, thereby realizing the function of safe unlocking which requires high technical requirements for the mobile phone itself. It is not yet said how much the safety performance of iris recognition technology has improved, and the speed of unlocking the mobile phone alone is also comparable to the speed of fingerprint recognition technology.
Which way is safer to unlock iris and fingerprint phones?In 2013, Apple took the lead in launching the fingerprint of mobile phones, launching its first fingerprint model iPhone 5s and immediately triggered the collective follow-up of the Android camp. In the following two years, before the mobile payment has officially opened the door, the fingerprint has been very limited in the country, and it can only be in the embarrassing situation of thunder and rain.
It seems to be a bit difficult today when we talk about innovation in smartphones again. Traditional hardware has been difficult to attract consumers' attention. On the contrary, some functions that seem to be gimmicks are expected to become a black technology after fingerprints, and iris recognition is one of the most representative technologies.
I remember that last year, Fujitsu showed a prototype equipped with iris recognition technology on MWC. You only need to stare at the front camera to be unlocked by infrared detection. Soon some new machines will use this technology to make a fuss, such as the Lumia 950 series launched by Microsoft, and some domestic eye recognition models such as vivo, ZTE, and Nubia. So what are the advantages and disadvantages of iris recognition compared to fingerprint recognition? In this issue, we found Microsoft Lumia 950XL and Apple iPhone 6s Plus.
Iris recognition
Before comparing the experience, we need to first come to the definition of the two.
Iris recognition is based on the iris in the human eye for identification, mainly used in security equipment and places with high security requirements.
We know that the structure of the eye is composed of the sclera, the iris, the pupillary lens, and the retina. The iris is located in the annular portion between the black pupil and the white sclera, and contains many detailed features of interlaced spots, filaments, crowns, stripes, crypts, and the like. After the iris is formed in the fetal development stage, it remains unchanged throughout the life course. These characteristics determine the uniqueness of the iris characteristics and also determine the uniqueness of the identity. Therefore, we can use the iris characteristics of the eye as the identification object of each person.
Iris recognition requires four steps, which are divided into iris image acquisition, image preprocessing, feature extraction and feature matching.
Iris/eye pattern recognition is differentWhen it comes to mobile phone iris verification, we have to talk about the difference between iris, eye pattern and eyeball recognition. Although the name is similar, in fact, there is a big difference between the three. The same point is that the front camera needs to complete the information acquisition, but the iris recognition is recognized by the annular iris outside the pupil, and it is collected with infrared rays.
Eye lines and eyeball recognition actually belong to the same category, mainly by identifying the venous blood vessel pattern of the white part of the eye through the camera. In general, the iris is more accurate than the white of the eye because of its own uniqueness.
Fingerprint recognition
Fingerprint recognition is a very common type of biometric recognition. It includes a pattern recognition system for modules such as fingerprint image acquisition, processing, feature extraction, and comparison. Fingerprint recognition is often used in places where personal identification is required, such as access control systems, time and attendance systems, laptops, bank internal processing, and bank payments.
Fingerprints are the lines formed by the uneven skin on the fingertips of the primate fingers, and may also refer to the marks printed on the objects by these lines. The detailed feature points of the texture have a starting point, an ending point, a joint point, and a bifurcation point. Since each person's fingerprint is not the same, the fingerprints of different fingers of the same person are different, so fingerprint recognition can be identified by comparing the differences of these detailed features. From the initial sliding fingerprint unlocking to the full era of push-type fingerprint unlocking, the advancement of fingerprint technology on smartphones is obvious.
Fingerprint recognition is divided into five steps, including image acquisition, image compression, image processing, fingerprint shape and detail feature extraction and fingerprint comparison.
Experience the duel
Lumia 950XL
Last year, we evaluated a lot of eyeballs and eye-striped smartphones, and the iris-recognized Lumia 950XL was the first contact.
Under the latest Windows 10 Mobile system, you can see the login options by clicking on the system and encrypting the device. For the first time you need to set a PIN code for your phone to prevent it from being recognized, and then you can enter the iris information. The entry process must ensure that the naked eye is entered, and the duration is about 10 seconds. In addition, you can choose to improve your recognition ability to get more accurate information recognition.
The Lumia 950XL is recognized by activating Windows Hello in the lock screen state. The mobile phone repeatedly searches for the user's iris through the front camera and infrared rays. When your eyes are about 30cm away from the device, the accuracy of device identification is higher, and the recognition time is about 2 seconds.
The accuracy of the iris recognition in the actual test is good, and the device can be accurately recognized even when wearing glasses. This is very good, and it can be smoothly recognized in places where the light is dim. However, if you want to play smart and try to unlock with photos or videos, you can't succeed. Once the iris is not scanned multiple times, you can unlock it with a pre-set PIN.
The Lumia 950XL does not have many iris recognition scenes. It only supports unlocking operations, not to mention passwords and mobile payments. And after multiple errors are identified, the system will lock the iris authentication by default. In addition, since Windows Hello is a beta version, I also encountered an accidental recognition system crash.
iPhone 6s Plus
With the same biometric technology, mobile phone fingerprint recognition has been popularized for more than 2 years, and the black technology is obviously more mature than iris recognition. The iPhone 6s Plus supports up to five sets of fingerprints. The entry process is divided into finger center texture and edge texture authentication. The unlocking accuracy is very high, and it supports 360-degree unlocking in any direction. Just compared to Android phones, Touch ID does not currently support unlocking in the screen-out mode.
In terms of functions, fingerprint recognition can be used for unlocking, replacing password input, and Apple Pay mobile payment field that will be launched in China. Compared to the more exaggerated authentication method of iris recognition, fingerprint operation is easier to use.
It's also very interesting to think about it. Maybe Microsoft is going to separate from Apple and Android camps in order to seek differentiation. Microsoft chose iris recognition, Apple and Android chose fingerprint recognition. In fact, Microsoft plans to allow all future Lumia phones that support the upgrade of Win 10 to join the iris recognition function, which means that those with infrared sensors can directly activate this function through firmware update. Microsoft's National Iris program seems to be advancing. With.
Iris recognition is cool, but it can't replace fingerprintsBy comparing the identification and application scenarios of iris and fingerprint, we can see the advantages and disadvantages of both. On the hardware level, iris recognition is simpler than fingerprint recognition. It only requires the front camera and infrared camera of the mobile phone. Fingerprint recognition also requires a separate sensor to inevitably add a certain cost.
In terms of security, iris recognition technology is better than mobile phone fingerprint recognition. After all, fingerprint recognition hackers can obtain fingerprints by acquiring fingerprint information, but since iris recognition can only detect iris information of living body, it can successfully identify users. Sexually has an advantage.
The ease of use and application scenarios are clearly superior to fingerprint recognition. After more than two years of development, mobile fingerprint technology is more mature than iris recognition, and can be applied in other fields besides unlocking, such as mobile payment, password recognition, application encryption, etc. Iris recognition can only be used as identity verification. The most basic unlocking scenes.
It can be said that the user has become accustomed to the simple operation of the fingerprint operation, but the interaction logic of the iris recognition has just started. Due to the jaggedness of the camera pixels, there are problems such as low recognition accuracy, long recognition time, scene constraints, etc., which may be long-term. "Challenging" the patience of consumers. This is why iris recognition looks very cool, but the popularity is still very long.
Nowadays, smart phones have completely entered the stage of biometric identification. In the past, fingerprint recognition only appeared on high-end models. Now domestically produced 100-yuan mobile phones can also be equipped with fingerprint recognition technology, and the popularity speed is obvious to all. Today's fingerprints are popular, we are seeing a black technology iris technology emerging from mobile biometrics. Although it may not seem so reliable at the moment, perhaps the iris technology that matures in a few years will completely liberate your hands and protect your privacy information more securely.
