The wheel of the era is rolling forward, science and technology are advancing constantly, and eyesight is everywhere. However, with the continuous development of technology, some of the drawbacks brought by technology have gradually emerged.

One

According to US Fortune magazine, Kneron, an artificial Intelligent Company in Santiago, successfully deception many face recognition payment systems including Alipay and WeChat, and completed the shopping payment process with a special 3D mask. The team also claimed that they had even entered Chinese railway stations in the same way.

Said Liu Juncheng, chief executive of kneron,This shows that face recognition technology does not meet the security standards, which will bring a threat to user privacy.

Founded in 2015, kneron is a terminal AI solution manufacturer that designs and develops software and hardware integration. Previously, they also announced the completion of the US $18 million A1 round financing led by Li Ka Shing's Weigang investment.

The core technology of kneron is to develop a high efficiency and low power consumption neural processing unit (NPU), which transfers artificial intelligence from the cloud to the terminal equipment, carries out real-time identification and judgment analysis, and develops the possibility of applying artificial intelligence to different levels.

Based on the size and product of the startup, it may be reasonable to guess this time

Two

Before that, there were also some related incidents about face painting payment being cracked.

In October this year, the science team of class 402 of Xiuzhou foreign language school in shangwai, Jiaxing, revealed that in an extra-curricular scientific experiment, they found that as long as a printed picture can replace a real person to brush his face, cheat the Fengchao intelligent cabinet in the community and take out the goods of his parents.

After that, Fengnao emergency off line.

As for the feedback received recently, it is verified that the application is a beta version of trial operation and is undergoing small-scale test. We have received some user-friendly feedback and have been offline for the first time. After improvement, we can pay attention to the announcement of Fengchao. Thank you for your support and encouragement.

It is reported that the current face recognition technology can be divided into two categories: based on 2D face image and 3D face image. When the Fengnest express cabinet camera collects the face, it only forms a 2D plane image, which is equivalent to a photo.

2D face recognition only takes plane image through 2D camera, so even if the algorithm and software are advanced, under limited information, the security level is not high enough, and it is easy to be cracked with photos.

So, some people ask questions. Is WeChat and Alipay's face payment more common in life?

Wechat said: wechat brush face payment uses the 3D live detection technology with the highest security level, and uses 3D, infrared, RGB and other multimodal information, which can effectively resist the attacks of video, paper, mask and so on.

At the same time, wechat payment will ensure account security through multi-dimensional security risk control strategy, and provide multi factor verification. Some users need to input mobile phone number or scan QR code bound to wechat account for verification, further improving security.

It is a very small probability event that wechat face swiping payment has potential risks such as account misuse and stealing. If the account capital loss is caused by face swiping payment, you can also apply for full compensation.

On the one hand, there is no doubt about the safety of the technology; on the other hand, kneron claims to have fooled the system with a special 3D mask.

At present, the matter is being further fermented, and WeChat and Alipay have not yet responded to the matter.

In fact, making such a 3D mask is extremely difficult, expensive and complicated.

According to the previous reports of mobile payment network, before making 3D masks, it is necessary to first use a high-precision 3D scanner to scan people and get 3D data; secondly, it is necessary to use a high-precision 3D printer to print out the main structure of the human head; most importantly, it is necessary to restore millimeter level facial features, including the height of skin color.

At the device end, when the user opens face painting payment, if he wants to use other mobile phones for face recognition payment and transfer, he must use the payment password to reopen face painting payment. In addition, when using other mobile phones to log in, you need to conduct login identity authentication, that is, you need login password.

In other words, if you want to use 3D mask to steal brush, you must meet several strict conditions at the same time:

  1. The high precision 3D model of Alipay user head is collected.
  2. Finish the manufacture of millimeter precision mask at no cost, and strive to be perfect;
  3. Alipay users can get the user's cell phone when they open the brush payment, or get the login password and payment password of Alipay users directly.

Obviously, in the actual operation, this method of stealing brush is not operable.

However, kneron also admitted that the fraud of using 3D masks is unlikely to be widely used, because the masks used by kneron are produced by professional Japanese mask manufacturers, with high degree of simulation and high price. But kneron also points out that the technology can be used to deceive celebrities or wealthy people.

People are always afraid of the unknown, but they can not escape their temptation, because people are greedy.

Because of greed, human beings are always exploring and developing. But everything is dialectical, and rapid development will bring unexpected changes.

But we should always believe that the generation and development of every technology is good intention at first. Maybe the purpose of human application of technology has changed the development of technology. But technology itself is not right. We can't stop eating because of choking. The positive effect of technology is still greater than the negative effect.

Just like face recognition, this technology has brought unlimited convenience and excellent experience to people. A hundred years ago, no one would have thought of today's scientific and technological development.

For AI technology, including face recognition, we should give it some opportunities to try and correct.

After all, Rome wasn't built in a day.
