How to evaluate the fingerprint identification mTouch of Meizu MX4 Pro, compared with Apple's touch ID? ...

Simple version:

1. The fingerprint identification scheme used by Meizu is provided by Ding Hui Science and Technology. According to the information on the Internet, it should be jointly developed by Meizu and Ding Hui, which greatly facilitates the use of future generations; Apple's is Authentec, which has been acquired by Apple, which has also caused that no other mobile phone can realize positive fingerprint recognition in the past year.

2. Meizu's fingerprint recognition is rectangular, and iPhone's is perfectly round. In the required area, Meizu's mTouch is dominant, which can make the lower border narrower. At the same time, Meizu has been pursuing the design of ultra-narrow bezel, so compared with the low screen ratio of iPhone, MX4 Pro undoubtedly has the upper hand.

3. Judging from the current evaluation, there is little difference in recognition speed and recognition accuracy between them, and both of them have reached a high level, which basically meets the practical requirements in hardware.

4. When there is little difference in hardware experience between the two, it is the application layer that decides the difference in experience. In addition to unlocking mobile phones, the biggest use of fingerprint recognition is mobile phone payment. Now Meizu only supports payment in its own store, and Alipay will take about half a year to support it. Apple has opened the interface of touch ID and launched Apple Pay, which has supported a variety of payment methods in the United States. But in China (╯□╰), it is on the same starting line as Meizu. If any of them can take the lead in supporting UnionPay or Alipay, it will greatly enhance the application experience of mobile payment. I look forward to Meizu's leadership in this regard and its deep cooperation with Ali. This is the correct way to hold Ma Yun's thigh tightly! !

The following is the official answer:

1. Technical parameters:

At present, there are two main solutions for mobile phones on the market: push-type and slide-type.

There are Samsung S5, HTC ONE MAX and so on. The supplier of this scheme is mainly Synaptics (the main supplier of notebook touchpad). Because of the poor experience, I won't talk about it here.

Let's talk about press fingerprint identification in detail: Since Authentec was acquired by Apple in the early days, everyone is looking for a solution similar to Apple after 5S came out. Huawei Mate 7 chose Swiss fingerprint card company, but Meizu thought that the fingerprint identification experience on the back was not good, and the FPC scheme limited the size of fingerprint identification module, so Meizu chose Ding Hui at the last minute. And what Mr. Nan said: "Engineers are hacking into fingerprint identification". Fortunately, Meizu successfully released MX4 Pro in 165438+ 10, and Ding Hui became an instant hit. Now many domestic manufacturers are waving checkbooks in search of Ding Hui.

The above picture shows the technical parameters of GT66 18/28 fingerprint identification module adopted by Meizu, in which the patented finger flash technology can realize the integrated operation from cold screen, wake-up to unlocking. When the screen is locked, the user can light the screen by pressing the HOME button and let his finger stay on the HOME button for a period of time to trigger unlocking, which is the same as the unlocking scheme adopted by iPhone6 in the screen locking state, but when the screen is lit, both can be unlocked by touching the HOME button.

Although I can't find the detailed parameters of touch ID, I think they are also composed of stainless steel ring, sapphire crystal cover and embedded capacitive touch sensor, and they also support input and recognition of five fingers and 360-degree reading of fingerprints, so the technical indicators are not much different.

2. Screen ratio:

I believe that I don't need to say much to know the gap between MX4 Pro and iPhone 6, which is also the biggest advantage of MX4 Pro. The reason for the huge screen ratio gap is largely due to the size difference of fingerprint identification module, and the other part is because Meizu and Apple are adhering to the design concept of symmetrical upper and lower borders (which I still support). At that time, the sexy chin of iPhone has fallen far behind. Although there is a reason why the fingerprint identification module can't make the bottom frame narrower, Meizu has indeed made a better product now (although I believe that Apple will not change the buttons from round to flat when it dies).

Screen ratio: iPhone 6: 65.85438+0%; iPhone 6P:67.8%; MX4 Pro 74.5 1%; (As can be clearly seen from the picture, the width of Meizu's lower border is smaller than that of iPhone 6, and the overall screen ratio also exceeds that of iPhone 6. )

From official website, Ding Hui, we can see that the width of the sensor used by mTouch is only 7.3mm, while the diameter of the round button of iPhone 6 is 1 1 mm, which is close to 4 mm, and this 4 mm makes it impossible for Apple to shorten the distance between the button and the screen and the bottom frame to be shorter than that of Meizu.

3. Recognition rate and recognition speed:

Judging from the current online evaluation, there is no substantial difference in unlocking speed between the two (some people say that MX4 Pro is faster), but the recognition success rate has reached a very high level, and the unlocking posture is not much different, and the use experience is basically the same. Because the recognition rate and recognition speed are not strictly tested, it is considered that both of them meet the practical requirements and are not expanded too much.

4. Practicality:

At present, in addition to a series of small unlocking functions such as unlocking mobile phones, unlocking applications and unlocking files, the biggest use of fingerprint identification is payment. Think about the steps we usually use online payment, such as logging into an account → clicking on the purchase → inserting online banking → entering the online banking password → confirming online banking → completing the purchase (Alipay and fast payment are relatively simple). If you have the fingerprint payment function, you can complete these complicated processes with one click, which greatly reduces the purchase.

After the release of IOS8, Apple opened the touch ID interface, launched the Apple Pay service in the United States, and officially entered the field of mobile payment. Despite all kinds of twists and turns and the resistance of some businesses, we finally took the first step. However, in China, Apple is still in arduous negotiations, and the integration of industrial chain is quite difficult even for an international company like Apple, which also provides opportunities for domestic manufacturers to catch up. For example, Huawei Mate 7 has cooperated with Alipay, and Meizu is also proceeding in an orderly manner. I believe that the good relationship between Meizu and Ali can make the cooperation progress rapidly, and we can look forward to the customized version of Alipay. However, at present, the status of Apple's app store is much higher than Meizu's, so in the case that both of them only support their own application fingerprint payment, Apple's practicality in this respect is still slightly higher.

5. Security:

Due to Apple's well-known technical strength, the security enclave module designed by Apple alone is used on the iPhone. According to the security manual, Secure Enclave is a built-in coprocessor in Apple's latest single-chip system design. Different from the application processor, the coprocessor handles the security startup sequence code and software update mechanism, and is responsible for the key operation of any data protection encryption operation and the complete process of data protection. Only Secure Envelope can access the user's fingerprint information, and Apple can't know it. Secure Enclave comes from TrustZone of ARM, and Apple has customized a highly optimized version of TrustZone. TrustZone security system consists of hardware and software partitions. Whether it is hardware or software, there are two areas, one is the security subsystem and the other is the normal area. TrustZone ensures that components in the normal zone will not access data in the secure zone. And those sensitive data are placed in a safe area to prevent many possible attacks. When security verification is required, Moniter mode will switch between two virtual processors independently and work in a targeted manner.

Meizu official website's safety description of mTouch is as follows:

It can be seen that both of them use the TrustZone technology of ARM, that is, trusted computing technology, so their security comes down in one continuous line. Although Apple made its own customization, I believe it won't make much difference. For now, I think Meizu has reached the safety level of Apple.

Summary and evaluation:

After many comparisons, it can be seen that Meizu's mTouch is comparable to Apple's touch ID. Meizu's advantage lies in its smaller identification module, higher screen ratio and faster unlocking speed (accurate comparison), while Apple's advantage lies in its industry appeal and industry integration ability. After all, for Apple, which controls the system and hardware, it has inherent advantages to promote the application development of fingerprint identification and expand the scope of fingerprint payment.

Now, hardware is no longer a problem for Meizu. More importantly, it expands the application scope of fingerprint identification. Apple has the ability to control Authentec in its hands and promote fingerprint payment independently. Meizu can't and shouldn't limit the technology of positive fingerprint identification to its own hands, actively promote the technology, let friends (that is, you, Xiaomi) use fingerprint identification quickly, and promote the application of fingerprint payment in China market. If China manufacturers can get through the fingerprint payment of Android first and make it bigger and stronger, it will provide great help for China manufacturers to face foreign Android manufacturers, and the competitiveness of Samsung Sony will further decline. As for apples, they are apples after all.

Update 1: Meizu and Ding Hui Technology

After the advent of MX4 Pro, Ding Hui Science and Technology, an originally unknown company, also appeared on the science and technology pages of major media. Here are the details of Ding Hui's technology.

Ding Hui Science and Technology Co., Ltd. is a small IC design company that has struggled for more than ten years. It has been unknown for several times and even faces bankruptcy. But this year, the sales revenue exceeded 1 billion dollars, and it is moving towards "1 billion dollars club". I started to make caller ID chips in 2002, and later turned to the research and development of capacitive touch chips. It was not until the first 10 touch chip came out that Ding Hui really entered the mobile phone industry, and the first customer was Bird. In order to be bigger and stronger, Ding Hui found the investment from MediaTek and introduced the quality management system and R&D system from MediaTek, which laid the foundation for the rapid growth of Ding Hui's shipping speed in the future. 20/kloc-in may, 2004, Ding Hui science and technology officially launched a fingerprint touch product prototype, and reached a cooperation with Meizu, sending a technical service team of more than 20 people to jointly complete the first positive fingerprint identification product in the Android camp with Meizu.
