The nanning evening news public number released a strange news on December 11. Huang Mouhui, a man from Hepu, Guangxi, owed huge sums of money due to gambling, and in a hurry, he even had a crooked idea of his ex-girlfriend Dong Mou. On December 26 last year, Huang Mouhui called Dong Mou and said that he would discuss in person about repaying him for more than 60,000 yuan during the love period. On the afternoon of the same day, Huang Mouhui went to the market to buy good vegetables and fruits and other items, and then went to Dong's residence. On that day, Dong happened to have a cold and was unwell. Huang Mouhui was considerate and took the initiative to cook for Dong and other housework. Also for its preparation of cold medicine, Dong Mou due to physical fatigue, shortly after drinking the medicine passed out. At 0:00 the next day, Huang Mouhui saw that Dong Mou was sleepy and difficult to wake up, that is, he used Huang's fingerprints to unlock her mobile phone, opened her eyelids, transferred 154,100 yuan through the face recognition function, and also took away one of her mobile phones and a coat. Huang Mouhui was eventually arrested by the police, and recently, Huang Mouhui was sentenced to three years and six months in prison and fined 20,000 yuan by the Xingning District People's Court of Nanning City.
In this case, in addition to Huang Mouhui's "scumbag" behavior being condemned, another focus is the transfer of money on Alipay through "rolling his eyelids and brushing his face", and many people have doubts in their hearts: Is face recognition not high-tech? How can it be so dramatic?
In this regard, Alipay customer service staff responded to the media: no similar feedback has been received, generally in the face recognition of the face is not successful, you can choose multiple locks. In case of similar circumstances, the user should promptly report to the police.
Is this really the case? Some netizens said that after many tests, rolling eyelids can really unlock face recognition.
Face recognition is a kind of biometric recognition technology that is based on the identity of people's facial feature information. The key to success lies in having a cutting-edge core algorithm and making the recognition results have a practical recognition rate and recognition speed. Face recognition technology integrates artificial intelligence, machine recognition, machine learning, model theory, expert systems, video image processing and other professional technologies.
In 2015, Ma demonstrated face recognition technology in Germany
After decades of development, the recognition rate and recognition speed of face recognition technology have been very high, and some experts said that the current screening target mainly relies on two aspects to ensure.
First, the system enters and compares more than 30,000 face feature points
Second, the system also relies on blinking, opening the mouth, turning and other ways to determine whether it is alive
So, if the human body is not awake, is it possible to recognize it through the face? In fact, Alipay's tone was less affirmative in response to another media outlet, upstream news, with a customer service claiming that although Alipay's face recognition accuracy rate reached 99.6%, combined with multi-factor verification such as eye wrinkles, the accuracy rate was 99.9%. However, there may also be a situation of "stealing": "As long as enough face recognition elements are obtained, the payment will occur." ”
However, the so-called "blinking", "shaking your head", "opening your mouth" and other actions do not need to prove that you are you, just prove that you are "alive"! In other words, as long as you get a photo of your face, it is possible to unlock face recognition. Don't think it's alarmist, it's really true. On November 2, 2021, CCTV reported that as long as you get a face picture and use the method of deep synthesis, you can make people's faces move, and easily break through some face recognition systems with false and real.
In the video, in the upper right corner is an original picture of a person. In the lower right corner is a driving video, and through specialized compositing techniques, the original person picture becomes a video on the left that shakes its head.
Moreover, in the synthetic video, people will not only shake their heads, but also do complex actions such as opening their mouths, nodding their heads, and blinking.
As early as November 2016, police in Yibin, Sichuan Province, cracked a case of using this facial recognition loophole to steal funds. Criminal suspects Zhou and Yang used this synthetic technology to obtain the permission to modify the account password of the payment platform, and then transferred the funds away, and by the time of the crime, there were more than 20 accounts involved, and the funds involved were more than 280,000 yuan.
Alipay customer service staff claimed that "the mobile phone also has several levels such as fingerprint lock or boot password, and if you want to get the mobile phone to open the payment function, the probability of being stolen is still very small." "But from the CCTV report, the probability is not small at all."
The essence of face recognition is to write the password on the face of the person, and make it public, so to improve the recognition technology to ensure the safety of people's property, face recognition technology still has a long way to go.
