Today, we're getting off to a good start in 2021 with the first big thing of the year: the Million Dollar Technology Awards. A nd this time, we've won two million dollar technology awards at a time. Congratulations to Xiaomi Seconds, MIUI Privacy Protection Team, and I'm proud of your innovation and courage!

These two projects, one is absolutely leading in the industry hardware technology, one is to let rice flour thumbs up software technology, on the same scale, are the industry's top innovation, have poured Xiaomi engineers huge efforts, are very popular rice flour, have a good reputation. Therefore, this year's million dollars jackpot on the two, hard and soft repair, good things into a pair!

This year is the second time we've awarded a million dollars. D r. Cui Baoqiu, Vice President of Xiaomi Group and Chairman of the Group Technical Committee, told me that a large number of outstanding hard-core technologies have emerged during this review process. I 'm really happy to see more and more behind-the-scenes heroes come to the front desk. Y ou represent more than 10,000 Xiaomi engineers, represent this heroic community, thank you for all you have done for Xiaomi! Here, I would like to share with you the results of xiaomi engineers' work.

120W wired second charge

Three innovations lead the future of the charging industry

Xiaomi 10 Extreme Memorial Edition was first used with 120W second charge technology, is also the world's first mass production of 120W fast charging products, full of 4500mAh mobile phone only takes 23 minutes. Since we were the first to boldly do a 120W second charge, equivalent to walking in the no man's land of technology, this young technology team has made remarkable innovations in the three core areas of hardware architecture, charging algorithms, and security strategy.

Xiaomi has achieved at least five industry firsts in hardware architecture: the first 120W-50W-10W triple fast-charge architecture, the first 4:2 direct charging architecture with an autonomous custom charging chip, the first butterfly dual-core structure battery, the first 6C high-performance graphene core system, and the first mass-produced high-performance 120W charger.

Not only hardware breakthroughs, Xiaomi has also made innovations in charging algorithms. Xiaomi second charge team in the industry pioneered the charging simulation evaluation method, can estimate 120W charging performance in advance, and optimize the design for bottlenecks, in order to improve the charging speed, Xiaomi second charge team also pioneered a multi-stage variable current control technology, charging speed compared to the traditional scheme increased by more than 10%.

The most important thing about charging is safety. I n terms of security policies, 34 security policies are provided. A mong them, the charger end 7 items, the motherboard end 18 items, the battery end 9 items. T his extreme protection is also certified as a safe fast charge system 3.0 by rhine-green T-V in Germany. In addition, Xiaomi uses a stand-alone MCU-plus algorithm to further improve charging safety.

MIUI privacy protection

All-round international leadership

In 2020, Xiaomi released two major versions of MIUI 12 and MIUI 12.5 within a year, with breakthrough improvements in security and privacy capabilities that have been highly recognized by users and national institutions. A s we all know, privacy protection has been the focus of global attention, and Android as an open system, there are still a lot of malicious APP in the unbridled theft of users' privacy. P rivacy protection is a fundamental requirement for every user. Whether chinese or foreign users, we should adhere to the highest standards and provide them with the same and ultimate privacy protection.

MiUI's security and privacy team is behind this to create the world's leading privacy protection capabilities. Xiaomi not only has the highest standards of privacy protection, the most stringent process management, the most extreme "design-started privacy protection" concept, and more importantly, we have the most rigid privacy protection technology.

MIUI 12 pioneered the Privacy Protection Trident: flares, interceptors and hidden masks. /b10>A flare is to record all events in the system and notify the user of the sensitive behavior of the application, giving the user the right to know. I ntercepting the net and hiding mask is to give the choice and management rights to the user, so that the user's rights management of the application is more powerful. S tatistics show that since MIUI 12 was released in May last year, the frequency of APP access to various types of privacy rights has dropped by more than 90%. In addition, Xiaomi participated in the construction of more than 100 industry standards, in the "mobile smart terminal security capability technical requirements" 2020 draft, "lighting bombs", "application behavior records" and other functions will be included in the mobile phone into the network standard security capacity level, become the necessary conditions for mobile phone access to the network.

Recently released MIUI 12.5, Xiaomi took privacy protection another big step forward and becoming a global leader. X iaomi first pushed the world's most comprehensive shear board privacy protection, users can decide whether to give users clipboard call permissions, the system can also intelligently identify the clipboard access through local algorithms, reduce user disturbance. P reviously, iOS 14 was the first to introduce fuzzy positioning, but its scope is limited to the range of communication base stations, the application can also determine the user's location through cross-base stations. U sing edge computing and big data support fusion fuzzy positioning service, Xiaomi has launched the world's first fusion fuzzy positioning based on differential privacy, and the fuzzy range can be adjusted at will. Finally, Xiaomi has developed Android's first default privacy isolation sandbox, which separates sensitive privacy information so that users can effectively protect photos and social information.

It is these innovations that make MIUI the first mobile operating system in the world to receive the Android Enhanced Privacy Test from Rhine-On-V, Germany. In June 2020, Xiaomi Security and Privacy Committee also through publicity month activities, to enhance the security and privacy awareness of the whole staff, so that Xiaomi's hardware and software products can protect user information security with high standards, and thus awaken the Internet industry and Internet users on the protection of information security and privacy awareness.

Million Dollar Jackpot

It's a demonstration of results, it's a determination to invest

Over the past year, Xiaomi has produced a series of convincing technical transcripts, such as DXO camera list 121 days, Xiaomi unmanned intelligent factory officially put into production, fast charge / wireless fast charging has always led the world, Xiaomi one finger technology release, the first release of the third generation of off-screen camera technology, etc. , in the global industry and consumer groups have caused a huge response.

Today, for the second time, we are presenting the Million Dollar Award, which has been awarded to three technical teams before and after. I n fact, behind the top podium, there are many teams that have come up with very good technical results. T he million-dollar prize was originally designed to make Xiaomi's engineers not only behind-the-scenes heroes, but also the brightest stars.

Xiaomi's 10th anniversary, we put forward the "technology-oriented, cost-effective, do the coolest products" this never change the three iron laws. T echnology-based is the first of the three iron laws. W hat exactly do we do? I think the most important thing is to do three things well.

First, always adhere to strengthen research and development investment. In 2020, Xiaomi invested nearly 10 billion yuan in research and development, and entered the top 20 companies in China.

Second, always attach importance to the construction of the talent team. /b10>Without top talent, innovation is the wood without the root, the water without source. I n 2021, Xiaomi will recruit 5,000 engineers, accounting for more than 20% of Xiaomi's current workforce. O ur camera department has nine research and development centers around the world, five of which are international. In short, where there is talent, Xiaomi goes where.

Third, always adhere to the creation of encouraging innovation, encourage research engineers culture atmosphere. /b10>Our success today is ultimately due to Xiaomi's strong engineering culture. E ngineers are Xiaomi's most important asset. T he Xiaomi Technology Award, which we set up, is the heaviest honor and award in Xiaomi's inner part today, and it is to highlight this point fully. As long as you love technology, as long as you are skilled, in Xiaomi you will be able to realize their technical dreams.

The million-dollar jackpot reflects our determination to stick to these three things. I am particularly excited and pleased to find that today we have won the million dollar award of the two technical teams are very young, Xiaomi is to give excellent young people opportunities, so that more young technical talent continue to emerge. This is Xiaomi to win the present, but also to win the future of the biggest bottom.

I also hope that Xiaomi all the research and development team, this year continue to refuel, to come up with more amazing technology results around the world. Early next year here, there will be more teams representing the world's top level to take more awards here!

At Xiaomi, we respect every crazy idea, we appreciate the courage to explore technological no man's land, and we embrace the bold trial and error on the road to success. I believe that only in this way, can use the fire of innovation to illuminate the future of Xiaomi, flying to the global rice flour in the mind of the stars of the sea!
