This article is transferred from WeChat public account “ Xia Ke Island (ID: xiake_island) “, author: cloud song, title figure from the visual China.

When I was staying in a hotel recently on a business trip, the front desk always asked me to verify the machine: when my face and the guy on the ID card successfully corresponded, I could check in. This scene is so familiar. I went to the bank to do business a few days ago. The teller asked me to “blink” and “shake my head” at the machine. When I entered the office building every day, the access control system reflected my face and job information on the screen. Mobile phone also has the function of turning on the face. (Although it has been turned off) , but once I could n’t open my hands and wanted to use the phone, friends Loudness said to me “You stretch your face over.”

Face is exposed day by day and has long been the subject of collection and identification. If you stop there, you won’t be surprised. But the key is that there is too much information that can be dug out from one face, ID number, shopping habits, financial loans, home address, sexual orientation … Once this information is leaked, you dare to imagine what will happen Is it?


Face data leaks have been reported frequently this year. First, a domestic technology company that provided face detection and crowd analysis was found to have no password protection on the face recognition database, resulting in the disclosure of 2.56 million user information. Later, it was disclosed by the Beijing Youth Daily that there were 170,000 facial data sold by online merchants in online stores.

The exhaustiveness of these 170,000 pieces of data is outrageous: covering portraits of 2,000 people, each with about 50 to 100 photos; each photo is paired with data, including 106 key points on the face, such as eyes, Ear, nose, mouth and other contour information, and even marked information such as gender, emotion, face value.

How did this information leak? Community access control, bank information comparison, hotel check-in verification, shopping malls, crossing the road … In many casual moments, our faces were “brushed” away.

This is not sensational.

In September 2019, a residential district in Shanghai installed a projection device in an elevator. It looks like an advertisement but is actually a face recognition device. At about the same time, China Pharmaceutical University in Nanjing installed a face recognition device in the classroom. It is said that it can track and identify students’ attendance, daze, sleep and other class status.

In some shopping malls and supermarkets, from the moment a customer walks into the door, the face information is captured without even knowing it, and it can even show their emotional state.

Why can I get so much information by brushing my face? The reason is simple. Face recognition is not just about detection and recognition. It can also associate face information with multi-party information to calculate more deep information.

What happens if this information is kept poorly or stolen maliciously? The first reaction of many people who pay with their faces is probably: broken! The vault is not safe.

China Judgment Documents Network recorded a case: In a robbery case, the victim said that he did not remember the password, but the assailant used the victim ’s ID card and payment software with face recognition to forcibly modify the payment.Password, take away a lot of money. In early August, a WeChat public account focusing on 3D printing released a test video-technicians used 3D printed wax figures to trick Alipay’s face recognition system and successfully buy train tickets.

Thinking about it, it’s kind of scary. If someone gets our face information and makes a 3D printed avatar, we will use our identity to violate the law and discipline. When we were held accountable, we couldn’t argue. Are you right? Who should we justify if we suffer material and mental losses?

What’s more terrible is that these injuries may not be one-off, and they are likely to haunt us for life. The reason is simple. Face information is unique and difficult to change biological information. Once leaked and covered with water, it will be difficult to completely heal the damage caused by the continuous diffusion of information.


Face recognition has caused some trouble, but it has also been widely used in life, especially in the fields of security and social management.

Taoyuan Airport in Taiwan has been connected to the face recognition customs system since 2013, which has greatly improved the efficiency of security checks. Shenzhen Airport has also used face recognition technology to intercept water passengers and capture absconding criminals since 2014 . From this perspective, face recognition technology should still be rewarded for its merit.

However, it is not 100%, and occasionally there are “mistakes”. One year, “Dong Mingzhu” ran a red light and was swiped by the news of “showing the crowd” on the street at the intersection. However, this is a pure misunderstanding, because what is displayed on the big screen is not the real Dong Mingzhu at all, but the Gree advertisement printed on the bus body.

Do n’t think that face recognition technology only “turns over the car” in China. Amazon ’s image recognition AI system Rekognition, launched in 2016, has also identified 28 US congressmen as criminals.

However, with the news below, you may not be able to laugh.

On October 29 this year, Zhan Minghui, director of the Beijing Rail Transit Command Center, revealed at the Urban Rail Transit Operation Development Forum that Beijing will apply face recognition technology to achieve passenger classification security screening.

How to classify security inspections? Research and establish personnel classification standards, form a corresponding face database, rely on the face recognition system to identify passengers, and push the information to security personnel, and security personnel accordingly take different security measures accordingly.

What problem does this cause? Once the system misjudges, we have been classified into unknown categories, and it is difficult to guarantee that it will not cause new types of social injustice. Nowadays, the credit information system gradually incorporates a variety of information, such as riding and crossing the road. If our faces are misidentified, which affects personal credit, who should take the loss?


Face recognition technology has been or may be annoying, so much to say here. In this case, should this technology continue to be developed and used? Does its existence increase efficiency or privacy? What attitude should you take with this technology?

Reviewing the use of face recognition technology so far, it can assist in tracking down drug dealers, traffickers, or it may be reduced to accomplices who misappropriate face information and perform illegal acts.

Have you noticed that the technology is still that technology, but the application purpose and scenario are very different, and the impact of the technology in the end is also very different. Therefore, how to make people’s face recognition technology “only benefit” and “do not make trouble”, compliance is the key.

It’s just compliance. It’s easier said than done. To be compliant, first of all, there are rules to follow. however
