Ali Has A "Seven Workshop" Specializing In "Brush Face".

Yesterday, Ma Yun presented to the world's most famous IT and communication industry event CeBIT (Hannover consumer electronics, information and communications exposition), to German Chancellor Merkel and vice premier Ma Kai of China, demonstrating the Smile to Pay face sweeping technology of ant gold clothing.

In order to prove the validity of the brush payment, he also specially purchased the Hannover 1948 commemorative stamps from Taobao on behalf of the guests.

It is understood that this new payment authentication technology is developed by ant gold clothing and Face++. After the shopping payment authentication phase, the traditional password is replaced by sweeping the face.

"In the future, we need not chop our hands and change the decapitation!" some netizens quipped that with the advent of "brush face payment", the purse will be more difficult to control.

Because, do not give cash, do not lose the password, the money went out loud!

The accuracy of face recognition is a puzzle for many people, but Professor Tang Xiaoou, a professor at Chinese University Hong Kong, has published a paper at the top international conference on computer vision CVPR2014. The accuracy rate of computer algorithm for face recognition has reached 99.15%, while the accuracy rate of naked eye recognition is about 97.52%.

Inside the ant suit, there is also a mysterious team specializing in biometrics, called "seven workshop".

Zhang Jie, a senior technical expert of the team, introduces the technology of face recognition based on neural network, which allows computer to learn human brain, and enables it to "recognize people" through extensive training of "deep learning algorithm".

And its accuracy rate is higher than the human eye, mainly because the computer can pay more attention to more key details, and through the algorithm, eliminate some interference factors.

This time, we have developed a Face++ with "ant face" in collaboration with ants, and have rich experience in face recognition. We have already worked with us, Camera360, magic and other photo software.

How do you play?

If a qualified institution needs face recognition, it may apply to the national identity card number enquiry service center, and compare the collected photos with the authoritative photo library of the Department.

That is to say, when people face recognition, they only need to open the camera of the mobile phone or computer, and shoot their faces.

But what about the make-up and plastic surgery? What about twins? "The person in charge of the ant's gold suit replied," basically you can recognize it unless you can't even recognize your father and mother.

It is said that

We will pay attention to the key details that many eyes are not easy to pay attention to.

The current technology can be done, one hair change, regular make-up, a certain degree of fat and thin changes, aging can be identified.

However, once the change is too great, for example, before and after cosmetic surgery, there is no difference between computers.

Twins need to adopt two factors to increase accuracy, such as adding a fingerprint or password verification.

If someone else took pictures of me? "

A big technical difficulty is how to prevent counterfeit products, such as using photos or videos instead of real people.

But at present, ant gold suits have studied scene based live monitoring, which has been able to effectively prevent face photos and face videos from muddling through.

The relevant person in charge of ant gold clothing introduces that the application uses the way of "interactive instruction + continuity judging +3D judgment" to avoid imposing.

To put it simply, it is to make you move, smile, blink, etc.

Then, what aspects of face recognition technology will be applied? Is it not possible for people to pay for their faces soon?

Ant gold clothing said that the passion for biometric technology is mainly for the Internet financial business to make corresponding technical reserves, and the related specific products are in preparation.

It will take a while to pay for the payment.

However, at present, Alipay's fingerprint payment has been launched. The face recognition technology is the latest research achievement of the team, and Ali has already begun to try out the "brush face punch card".

Coupled with the fact that Lao Ma has worked so hard this time, we can guess that the distance from the "brush face payment" is not far away.

"Seven workshop" responsible person said that before, we used to use user names, passwords and identity cards, dynamic password to verify user identity.

In the future, it is likely that users will be turned into biometric features to identify their identities, such as faces, fingerprints, palmprint, iris and so on.
