If you are a Xiaomi user and have been updated MIUI12, should have a deep impression on its new added Xiaomi privacy feature.

In MIUI 12, Xiaomi privacy function has been built into Xiaomi privacy brand. In terms of products, it has a series of functions including flare, interception net and concealment mask. (pingwest has also done some experience before. The content is in《 And we took MIUI12 apart》)

When it comes to privacy protection, in July, Cui Baoqiu, vice president of Xiaomi group and chairman of the group's technical committee, also reviewed the user privacy protection functions of previous MIUI versions for us: in 2012, MIUI had added self startup management; in 2013, MIUI proposed runtime permissions; in 2014, location-based installation scanning came to MIUI; in 2015, the location-based installation scanning came to MIUI MIUI also released a private photo album. In 2016, MIUI added pseudo base station interception; in 2017, the application lock was fully upgraded; in 2018, MIUI added device identification; in 2019, MIUI added user-defined permission description.


Friends who understand the Android version update should also know that Xiaomi many function development is actually based on the Android version update, part of the upgrade is a trend. But because the domestic mobile phone market is relatively independent, some functions are also MIUI

One observation is: if you focus on several domestic friends, Xiaomi is really ahead in privacy protection, or put forward relevant functions and concepts earlier.

Cui Baoqiu said that in 2015, he had set a flag for himself and a flag for the privacy Committee, which was to build information security and privacy protection into a brand of Xiaomi, so that users could pay attention to their own information security.

flag, for 2015 were initially realized in 2020.

No man's land

Time can be dial earlier, Cui Baoqiu in 2012 by Xiaomi Group CEO Lei Jun extended to Xiaomi company. When he joined Xiaomi after IBM、 Yahoo and LinkedIn in charge of information technology, he formed a team of Xiaomi artificial intelligence and cloud platforms, leading Xiaomi


Lei Jun told him

In 2012, Xiaomi's information security team was established, which to a certain extent solved the problems of Xiaomi in website operation and user data storage.

In 2014, Xiaomi international business began to layout, but problems also appeared.

Cui Baoqiu found that in the privacy protection, with Xiaomi's knowledge and experience, and even technology, personnel and awareness are far from enough. Xiaomi's products to go to sea, the results in large and small markets facing various pressures. So, inside Xiaomi

There's no example to learn, it's

For Cui Baoqiu, he went to the United States in 1995, graduated from the Department of Computer Science at State University of New York, Shixi, and has been in contact with software engineering in the United States for more than 20 years.


In 2014, Xiaomi's privacy principle came out, which was divided into five parts. First, inform / know; second, option / consent; third, controllable / participation; fourth, integrity / safety; fifth, enforcement / remedy. Several parts also confirm the function upgrade of Xiaomi in previous MIUI versions.

Today, with the change of the international situation, as well as the domestic attention to information security and privacy protection, millet privacy principle is upgraded again, which has become corporate responsibility, user controllable, openness and transparency, security and legal compliance.

Attack and defense

Perhaps because of this, privacy protection has been written into Xiaomi's team culture in the past few years and has become an important part of the engineering team.

Compared with the fuzzy definition of privacy information and personal information six years ago, the use of big data technology has made privacy protection more complex.

For example, the use of personal data has brought users more accurate push, and some applications have also entered the forbidden zone of privacy data abuse.

In 2018, China's development forum, Baidu chairman and CEO Robin Li said that the Chinese people love to sacrifice privacy for some convenience.

He further added:Many Chinese users have no choice but to be forced, deceived, fooled, and unknowingly stolen their privacy by some malicious apps, or they have no choice but to give up their privacy.

And it also confirms the privacy principles of user control and transparency advocated by Xiaomi in the MIUI12. A flare lets users know which app are secretly starting and calling, while a hidden mask gives users the right to push the user to zero the ad data and re-open it

In fact, security and privacy are twins, but the security protection of privacy is essentially attack and defense.

Cui Baoqiu, for example,Five years ago, Xiaomi insisted on protecting IMEI as private data under the pressure of various businesses and the pressure that engineers and managers did not understand. It was not until the release of Google Android 10 in 2019 that Google officially announced IMEI as private data and removed access control.

IOS has done much earlier in the IEMI case. As the unique identification code of the device, IEMI cannot be recovered. It is permanently bound to the device when it leaves the factory. It is used in many applications for user data tracking. After Apple banned access to IEMI numbers on IOS 5, it encountered a lot of resistance from advertisers who wanted to track user data. However, IEMI was not the only device identification code. Advertisers began to track Bluetooth and WiFi addresses, and then Apple banned access to MAC addresses of devices on IOS 7.

Another case: Xiaomi added a photo security sharing feature to the MIUI12. Briefly, an ordinary photo taken may display user privacy information such as location, time, etc. in a professional image editing software. The MIUI12 security sharing logic is to jump from the original location to the background security sharing to process the information and then jump back to the original address to continue sharing. But the WeChat share tick


A river, a sea

This means that privacy protection should be an ecological concept.

To a certain extent, advertising software developers are the community of interests, wantonly occupying the interests of a large number of ordinary users. Huge independent apps have independent control rights, and each application may involve the privacy of users. The platform side's right to protect users' privacy is only to inform, but it has not yet reached the completely autonomous and controllable power.

Xiaomi's miui12 is also the same, it can only make users see, less forced to choose.

Cui Baoqiu so metaphor this ecology,

So, what role can Xiaomi play?

He said.
