Since the advent of the Electronic information age, people have never stopped the research on information security, especially the security issues based on personal privacy. In the past few years of the rapid rise of smartphones, mobile phones carry a large amount of personal information of users. Once lost or the power-on password is cracked by someone with a heart, the private photos, bank card passwords, secret documents and other information will be obtained by criminals. , causing huge losses to individual users.

The password lock of smartphones has also undergone an upgrade from digital passwords, gesture unlocking to fingerprint recognition, and now iris recognition and face recognition have entered the stage of history. It can be expected that in the near future, fingerprint recognition will also complete its mission and be abandoned by smartphone manufacturers, one is because of the popularity of comprehensive screens, and the other is because the new FaceID technology will be safer and more convenient to use. The transformation of biometric functions has become a product selling point for smartphone manufacturers.

Smart devices will be fully built-in biometrics

The latest report from Acuity Market Intelligence shows that smartphones will increasingly use biometrics, and it is expected that two-thirds of smartphones sold globally will be equipped with biometrics this year, and by 2019, all smartphones shipped Biometrics will be built in. Fingerprint recognition has become common in Android phones and has become standard in mid-range phones. By 2020, it is expected that all smart devices, including tablets, will fully use biometric technology.

Is the fingerprint recognition function coming to an end?

Since Apple’s iPhone 5S products are equipped with fingerprint recognition technology, the technology has developed from a tasteless function to a must-have feature of smartphones. Until the appearance of IPhoneX, the fingerprint recognition technology could not be applied to the full screen without the Home button, but was replaced by the face recognition function. According to well-known gods, all of Apple’s new phones will give up fingerprint recognition technology next year, which also means that iPhone is more inclined to choose Face ID in password recognition technology, and fingerprint recognition is finally going to be lonely.

Many models of domestic manufacturers have placed the fingerprint recognition function button on the back of the fuselage, which also greatly affects the user’s experience of unlocking the screen and using Touch ID for payment transactions. At this time, if there is an option Domestic manufacturers are also very happy to replace it with new technologies.

In fact, the rise of fingerprint recognition is entirely due to the uniqueness of each biological fingerprint, and its technical difficulty is not too high, so the fingerprint recognition function is the earliest biometric technology used. When most mobile phone manufacturers design the fingerprint recognition function, the priority is their market recognition, not technical problems.

With the popularity of full screen, mainstream models such as Apple, Samsung, Huawei, Xiaomi, and VIVO have begun to try full screen. Now that the fingerprint recognition function under the screen is not mature, the use of full screen means that the front fingerprint recognition function needs to be used. Abandoned and can only be carried on the back of the fuselage. When FaceID becomes more and more popular, the fingerprint recognition function will once again become a tasteless function, and it is reasonable to be abandoned by manufacturers.

What is the difference between fingerprint recognition and face recognition?

When it comes to fingerprint recognition, one of its most important elements is its capacitive sensor, which functions to capture fingerprint images. When a user performs fingerprint collection, a capacitive array is formed by a capacitive sensor, which is stored in a specific database after image processing. When performing fingerprint recognition to unlock or pay, the capacitive sensor will transmit the re-captured fingerprint image array to the function processor for comparison with the original fingerprint image array stored in the database. When the coincidence of the two image arrays reaches the specified When the ratio of , the processor will send a signal to the unlocking screen process for determination, and the system will perform the unlocking process. The same mechanism is also used for fingerprint payment.

The application of face recognition needs to consider multiple factors such as complex lighting, biological dynamics, and obstructions. The recognition difficulty is high, and the natural cracking difficulty has also been upgraded. It has raised the security level of biometric password unlocking by one level, and the recognition accuracy has improved. Also more than 10 times. Especially in terms of security, face recognition is more difficult to crack than fingerprint recognition.

1. In terms of service life, fingerprint recognition technology is lower than that of face recognition. Its biggest weakness is security, and the biological characteristics of face recognition are difficult to be forged, so the fingerprints in the movie are collected and replaced by an imitation. The situation that can be unlocked is impossible at the level of face recognition.

2. The cost of face recognition is lower than that of fingerprint recognition, and its application range is wider. It can be used in fields such as transportation, public security, security inspection, and household registration. In smartphones, face recognition is mainly used for screen unlocking and payment. It is the same as fingerprint recognition, but using face recognition does not require expensive touch sensors, which can save manufacturers a lot of hardware funds. cost.

The hidden danger of biometrics

Although the biometric function is already high in security, its uniqueness and immutability make it face greater security problems. That is, once the information is leaked, the loss to the user is also huge, and all his information may be stolen. What is even more frightening is that as the only biometric feature, the stored face information cannot be changed after being stolen. That is to say, this function can no longer be used in the future. This is true of fingerprint recognition, and the same is true of face recognition.

Mainly talk about the face recognition function. With modern technology, with the help of the three-dimensional model generation system and bionic skin, after obtaining some basic images and video data of the target user, a basic model that can deceive the face recognition system can be synthesized. Appropriate processing and upgrading can well cope with face recognition technology in different states. Of course, the workload in the early stage is still very large, and ordinary users do not need to worry about being targeted.

Fingerprint recognition prostheses are more convenient and less difficult to make. A lot of them can be found online, and even non-professionals can operate them. So, this brings two levels of thinking:

1. The application prospect of biometric function

Using biometric technology, it is possible to carry out cross-border cooperation and research in public security criminal investigation, transportation, and other fields such as physics and chemistry, and launch safer and more reliable products. Combined with the current big data technology and deep learning technology, the biometric function will play a controlling role in industrial integration as a mainstream intelligent model, which will be more meaningful.

2. Are there better alternatives to biometrics?

The uniqueness of biometrics itself can well guarantee the privacy of its user information, but the subtext of something that is too private is that the consequences will be more serious if it is lost, and privacy and security are contradictory and contradictory, we will pay for it. As for the application side, only one point can be selected for development.

Of course, in terms of recognition accuracy and safety, vein biometrics is the most secure, but because of its high technical cost, it is difficult to commercialize it at the current level of technology.

The current biometric identification technology is still in development, and there is still a lot of room for improvement. Although the fingerprint identification technology and face identification technology introduced by major mobile phone manufacturers are flawed, they can still meet the needs of users in practical applications. of. In terms of security, it is a big deal to superimpose passwords, fingerprint recognition, and face recognition, but it is difficult to solve the problem of poor user experience. Of course, we are still willing to take a supportive attitude and view biometric technology rationally. At the same time, we should not be careless and always be vigilant about information security issues to prevent criminals from taking advantage of it.
