"Brushing face" law enforcement raises privacy concerns



According to the reading: “Come on a wave and go away, no matter the red light”, traffic chaos by pedestrians and non-motorized vehicles is common across the country. Recently, some places have adopted “brushing their faces” to enforce the law in order to eradicate this “illness.”

“Come on the road and go away, no matter if the traffic lights are red,” and traffic lights for pedestrians and non-motorized vehicles are common across the country. Recently, some places have adopted “brushing their faces” to enforce the law in order to eradicate this “illness.” Beijing's Tongzhou District piloted a high-tech system for real-time capture and loop playback. In Shenzhen, the “Intelligent Pedestrian Red Light Forensics System” was launched to realize the transition from a tube car to a pipe manager. At present, high-tech means such as "face brushing" and law enforcement are in the trial phase. This practice has also raised concerns about privacy while showing high efficiency.

"Brushing face" law enforcement raises concern

“During the take-away, this time is the most important thing. When you come across the intersection, no matter the red light, you can pass it. Now there is no license for the electric vehicle. Can't beat it. Where is the traffic control department?” Name Li Xing take-out delivery staff said. However, in Shenzhen, this idea may not work.

Recently, the Shenzhen traffic police took the lead in implementing “brushing the face” law enforcement in China, that is, making use of high-definition equipment to photograph the actor’s illegal process and comparing the facial features of the actor with humans. After the manual review, the identity information of the offender was determined and a penalty was imposed.

According to Xu Wei, chief of Shenzhen Jiaotong Police Bureau, outdoor factors such as weather and light changes basically do not affect forensics. The hardware and software conditions of the device can support the opposite face, head, shelter, backlight, high brightness, and high flow density. Identification of such. "Non-motorized vehicles can perform effective snapshot recognition even if they travel at 30 kilometers per hour."

“You have taken a red light, please return it to the stop line!” A cross-section of Jiuke East Road and Liyuan North Street in Beijing’s Tongzhou District has been equipped with real-time capture of high-tech equipment since April. The speaker will make such voice prompts, and the large screen in the northwest corner of the junction will also broadcast the pedestrian's red light screen in real time.

"This system works well. Some young people do not pay attention to moving forward. The system has reported "red lights" and he has returned." Assistant police officer Weng Chengwu on the roadside said to the writer.

High-tech means to rectify red light chaos has a realistic background. According to statistics from related departments, in the annual traffic accidents, 53% of traffic accidents caused by death were caused by pedestrians and non-motorized vehicles crossing the road and caused by red lights. This has become one of the major killers of traffic safety. In addition to Beijing and Shenzhen, many places across the country have also introduced high-tech methods to rectify red lights. In Suqian, Jiangsu, and Xi'an, Shaanxi, some face-to-face traffic and densely populated intersections were equipped with face recognition snap-shooting systems, and some also set up educational punishment stations for pedestrian non-motor vehicles to regulate traffic order.

“The current exploration of high-tech governance using red light has positive significance, which is beneficial for improving the efficiency of law enforcement and reducing the occurrence of illegal activities.” Chen Yanyan, Dean of the School of Urban Transportation of Beijing Polytechnic University, told the newspaper that explorations and explorations in these different places have been conducted. There is no precedent in terms of technical means or punitive measures. Therefore, it is worth encouraging to invite everyone to discuss in a certain period of time.

High-tech means focuses on specification

High-tech tactics look "cool". What about success?

Taking the Xinzhou Lianhua Intersection in Futian District of Shenzhen as an example, the data show that after half a year of the opening of the system, pedestrians' red light violations dropped from about 150 cases per hour to 8 cases per hour. I learned from many visits that the tips or snapping equipment at the intersection would give psychological warning to pedestrians to a certain extent, thereby reducing the probability of a red light. "Beware of crossing the street later." A Shenzhen citizen said.

“High-tech law enforcement is a trend of development. It takes a lot of manpower to rely entirely on manual management of violations, and its limited coverage means that there will be a large number of supervised blank areas. Now it depends on machine tracking and face recognition. Accurately capture the trajectory of pedestrians in the road space, accurately enforce the law, and provide a basis for punishing violations and violations, said Chen Yanyan.

The vast majority of these high-tech means are still in the trial stage and are only implemented at some intersections. There are costs and other considerations. Chen Yanyan analyzed that technology costs are a matter of stages. The prices of high-definition video and cameras in the future will continue to fall, and the cost will not be a core issue. At present, high-tech law enforcement is still more exemplary.

On the one hand, many pedestrians are not aware of this practice. Wang Qiang, a white-collar worker working in Shenzhen, found that at the red light (more than 50 seconds) at Renmin Road and Baohua Road intersection in Longhua District, Shenzhen, there were still about 10 people on the sidewalk. “This is an intersection with a large number of people. It is easy for everyone to get together and wave a red light. There is a big screen and shooting equipment here, but after all it was just installed, it is estimated that most people still do not know.” Wang Qiang said. On the other hand, the ultimate purpose of introducing high-tech means is to regulate traffic order, not for punishment. Expert analysis, which also means that "brushing the face" of law enforcement and other trials is unlikely to be implemented in a short period of time.

Adopting new technologies must also establish rules

"Face brushing" has increased the accuracy of law enforcement, and has led to debates about privacy protection. Coupled with the implementation of some places or plans to implement red light personal information exposure, red light and credit linked to other measures, further exacerbated people's concerns.

In response, Shenzhen responded that “brushing the face of law enforcement is only a method of forensic evidence. It is similar to the identification of license plates for motor vehicles. It has a special management system, and does not publish illegal information to the public. It does not announce the name of the traffic offender. ID information and other key information do not provide inquiries. Only when the parties have objections can the relevant illegal information be viewed."

Zhu Xi, deputy director of the Communication Law Research Center of China University of Political Science and Law, suggested that relevant information collection and exposure should allow citizens to know in advance and obtain consent. “The premise of 'face brushing' enforcement is to complete the collection of information for pedestrians, integrate the information into a large database, and compare it with the existing database of citizens' personal information. This practice is not only costly, but also protects the privacy of citizens. Affected.” Zhu Xi told the newspaper.

Law enforcement has attracted attention. A bigger background is that the Internet and the mobile Internet are increasingly asking consumers for more accurate personal information, including facial and fingerprint biometric information. The ubiquitous information gathering and the exposure of information that has occurred in time have triggered more anxiety about privacy being unprotected. Experts believe that in the era of mobile Internet, regardless of relevant organizations, such as traffic control departments, education departments, social security departments, etc., or a large number of businesses, such as online shopping, take-out companies, etc., almost every day is collecting a large amount of information. In the past, this type of information was mainly static, such as personal basic information, basic family status, housing and property status, and so on. Now, the "brushing the face" law enforcement and other practices are extended to dynamic information, and grasp sensitive information such as behavior trajectories. Some people feel that tension is normal.

Zhu Xi said that social management adopts new technologies, and at the same time, they must establish rules and draw red lines, accelerate research and formulate laws and regulations concerning the protection of personal data. Prior to this, citizens should pay more attention to self-protection in daily life, such as not revealing WeChat account casually and not trying new payment methods easily. Enterprises should also respect the user’s right to know and withdraw, such as when consumers delete their accounts, they no longer use their relevant data. The management agency should also handle the relationship between management and protection. (China Business News)
