In the first half of this year, in Shanghai, Xuzhou, Jiangsu Province and other places, there were many cases of wearing silicone face masks and stealing from people disguised as others. The use of silicone face masks to disguise as new faces to commit crimes is becoming a new method for some criminals to commit crimes. Where does this mask come from? Can it really easily pass through all facial recognition systems?
Silicone hoods derive new criminal methods
Whether it can pass the face recognition system
After the suspect was arrested, the police found silicone face masks among the items he carried. According to a comprehensive analysis by the police, the use of silicone masks, wigs, helmets and other props to commit crimes after careful camouflage has shown an upward trend in recent years.
In both cases, the silicone face mask worn by the suspect when committing the crime was purchased online. With this clue, the reporter of "Financial Investigation" searched on multiple e-commerce platforms, and sure enough, he found that many merchants were selling related products.
The reporter found that the merchant also swore in the detail page that their products could pass the face recognition system.
In order to verify the authenticity of these products, the reporter went to the offline studio of this online store under the guidance of customer service. The staff introduced to reporters that the mask with only a silicone face costs 3,200 yuan, 6,800 yuan with a hair transplant, and 15,600 yuan for a customized one, and needs to provide data on facial features.
The custom silicone hood process is not complicated, but the cost is higher, mainly because it is time-consuming, and the longer it takes to make the more refined it is, the higher the degree of restoration. Its reduction degree can reach about 90%, and it is quite close to real human skin regardless of skin color or feel.
However, the staff of the studio also said that wearing their silicone face mask does not guarantee 100% passage through the face recognition system, because even if the appearance similarity reaches 80%~90%, the face recognition scanning is affected by uncertain factors, such as lighting problems.
Another silicone face mask manufacturer in Huiyang District, Huizhou City, Guangdong Province, is confident in the products it produces.
The commitment of each manufacturer to the degree of restoration is not the same, and on the issue of whether it can be passed by face recognition, some people in charge swear, and some dare not guarantee it.
Can silicone masks really fool facial recognition systems?
Film and television special effects practitioners tell the truth
The reporter of "Financial Investigation" came to Hengdian Town, Dongyang City, Zhejiang Province, and found a studio specializing in providing special effects props for the film and television industry. Here, the reporter saw a variety of film and television level simulator props.
With the help of special effects technicians in the film and television industry, the simulator props that the reporter saw here can be described as vivid and lifelike, reaching a level that is enough to be fake. As for whether these simulator props can pass face recognition, practitioners in the film and television industry have different opinions.
The person in charge of the special effects studio told reporters that from the perspective of film and television shooting, the 1:1 restored silicone model can be fake, but if you want to pass the face recognition system, such a mask will be affected by the wearer's own face shape and skeleton size, and the slight difference will reduce the effect after the final wearing.
The person in charge of another special effects studio believes that the use of silicone face masks as camouflage to commit theft crimes should indeed attract the attention of the public security organs, but as the online merchants said, they can open the electronic door lock by customizing the silicone mask, and through the face recognition system, it is not very realistic from the current technical point of view.
After a front-line investigation in e-commerce, manufacturers, and professional film and television props companies, the reporter learned that the simulated silicone face mask can be privately customized, and the price quoted by the production company ranges from 15,000 yuan to 100,000 yuan, but it usually takes one to two months to professionally customize a silicone face mask.
A number of business leaders interviewed by reporters told reporters that at present, except for the formal needs of special industries, there are not many ordinary consumers who really order. Although there are many people who inquire about this on the Internet, there are also many people who are dissuaded by the price of the product and the production cycle.
Cheated access control, broke mobile phones, and stole accounts
Can silicone face masks fool face recognition?
In order to find out whether the silicone face mask can break the face recognition system, the reporter of "Financial Investigation" came to the network security center of the China Electronics Standardization Institute and carried out the test under the guidance of laboratory professionals.
Test 1: The first attendance machine
Step 1: The tester puts on a silicone face mask and enters the face information of the silicone face.
Step 2: Clock in as normal.
Result: As the machine reported "checked-in", it proved that this access control attendance machine with dual cameras was quickly successfully broken by the simulation mask.
Test 2: The second time and attendance machine
Step 1: The tester wears a mask, and the face information is smoothly entered into the attendance machine of the new test.
Step 2: Clock in normally.
Result: As the machine error prompt sounded, it meant that the silicone face failed to fool this market-ready attendance machine.
The tester told reporters that the second attendance machine optimizes the real person recognition model in the algorithm, and this data calculation method can effectively block non-real human targets and improve security.
Test 3: Smart Door Lock
Step 1: The tester wears a mask and enters the face information.
Repeated attempts by reporters and testers failed to record the face information of a person wearing a mask. The tester told reporters that the complex data algorithm of the smart door lock identified that the "mask face" was not the effective face data of a real person, so it refused to collect and enter.
Test 4: Smartphone
When the reporter used the mobile phone to scan the real face data, the mobile phone quickly completed the collection of face data; But when the tester put on a silicone face mask and started scanning the mask's face data, the phone's scanning program did not respond.
Through the test of professionals, the vast majority of current face recognition devices and computer algorithms can easily identify the fakeness of this silicone face mask. This kind of silicone face mask sold on the Internet has no effect in front of attendance machines, smart door locks, mobile phone scanners and other devices. Regarding the so-called rumors in the society, the tester told reporters that there is no need to worry.
He Yanzhe, deputy director of the evaluation laboratory of the network security center of the China Electronics Standardization Institute, told reporters that in most cases, face recognition requires multiple verifications, and the enhanced face verification identity technology of the current head manufacturers can effectively intercept attacks and accurate identification, with an accuracy rate of more than 99%.
Despite this, industry insiders also suggest that the public security department should record and strictly review silicone face masks and production companies with a high degree of simulation. At the same time, the relevant departments should also increase the supervision of the sale of artificial masks by e-commerce platforms to prevent them from being used by some criminals.
