The man pickpocketed the eyelids of his ex-girlfriend and transferred more than 150,000 yuan to be sentenced

Experts: Face recognition, like traditional authentication technology, does not exist 100% secure

A few days ago, the Xingning District Court of Nanning City, Guangxi Province, tried a special theft case. Taking advantage of his ex-girlfriend's coma, the defendant successively passed fingerprint and face verification and repeatedly transferred a total of more than 150,000 yuan from the woman's mobile phone. Without knowing the unlock and payment passwords of the mobile phone, how did the defendant succeed in committing the crime?

The woman was unconscious and was unlocked by the eyelids to unlock the phone and turned away 150,000

The case occurred on December 26, 2020, when defendant Huang Mouhui came to the home of his ex-girlfriend Dong Mou in the name of discussing repayment, saw that Dong was sick, and also took the initiative to cook and feed medicine. Judge Li Zhifu of the Criminal Trial Division of the Xingning District Court in Nanning City introduced that Huang Mouhui took advantage of the opportunity to flush cold medicine and poured the drug he bought into the water in the kitchen. Huang Mouhui took advantage of Dong's coma period to unlock her mobile phone with her fingers, open Dong's eyes with her hand, log in to the victim Dong's Alipay, and modify the payment password inside and transfer money in Alipay.

The police found that Huang Mouhui transferred a total of 154,100 yuan from Dong's huabei, borrowing, Alipay balance and bank card on several occasions that night. Recently, the Xingning District People's Court of Nanning City made a first-instance judgment on the case, and Huang Mouhui was sentenced to three years and six months imprisonment for committing theft, and fined 20,000 yuan, and ordered him to return all the economic losses of the victim, Dong Mou.

Smartphones may be opened to pass verification

Tian Tian is a doctor of artificial intelligence at Tsinghua University and has been committed to the improvement of artificial intelligence security technology. He told reporters that whether it is the 2D face recognition technology used by low-cost mobile phones or the mid-to-high-end mobile phones with 3D face recognition technology, it is possible to passively open the eyelids and pass the face verification.

Tian Tian said that face recognition technology is actually through the algorithm to extract some key information of the face, the eyes, nose, mouth and other surrounding areas will have more key points, so in fact, if there is some interference in the face recognition process, cheeks or foreheads, it may not have a particularly large impact on identity recognition.

Because of this, most of the current software will add live verification technology on the basis of face recognition, that is, it is necessary to make nod, blink, and shake the head.

Face fingerprint payment must be both convenient and secure

Experts say that in theory, the more technical aspects of verification, the higher the security. However, in actual operation, if the security level is adjusted to the highest and the certification is repeated, the convenience will be affected and the user experience will be greatly reduced. Compared with the bank App, Alipay only has a blink of an eye when it is verified in live, and WeChat can transfer money only by verifying fingerprints in some models of mobile phones, in addition to the difference in technical routes, there are also market strategy choices.

Experts emphasize that face recognition, like traditional identity authentication technologies such as passwords and fingerprints, has a certain probability of being breached, and there is no 100% secure technology at this stage. For users with high security risks, or in specific scenes where they rest in public spaces such as bathrooms and beauty salons, you can completely turn off the face brushing and fingerprint recognition functions in the mobile phone settings, so that when unlocking the mobile phone and payment verification, the option to brush face and fingerprints will not appear.
