The 3.15 party exposed the security hole of the face recognition technology: in the field test, you can use the software to modify the face image for face recognition, thus bypassing the network real-name authentication system.
A smile of evil spirits shocked the nation to eat melons!

and so. . Do you dare to use the method of brushing your face to make online payments, right?
Is artificial intelligence recognition accuracy a false proposition?In recent years, I have always heard people say:
The image recognition accuracy rate of XX artificial intelligence software is as high as 100%, and the accuracy of speech recognition is how much...
Reliable, surrounded by a full sense of security - with a face login or payment, Ma Ma no longer have to worry that I can not remember the password!
Before telling Ma Ma, let's first take a look at what face recognition is?
There are many ways for computers to perform face recognition, which are divided into 2D and 3D. At present, the mainstream algorithms are simply identified by face feature extraction, neural network training and classification:
For example, in a technical competition in the early years, a company identified the face on a multi-blurred picture by grabbing feature points and took the first place in the game.
However, if you take a picture with similar feature points in the fuzzy photos identified in the contest, the company will recognize the software. Is it true that even if the original picture is "King Kong", it will be recognized as an adult face?
Why do you say that?
Because to identify such a high-blurred picture, it is necessary to reduce the unrecognizable rate, the scope is expanded, and it is bound to increase the error rate.
This example may not fully explain the problem. The reason why "the artificial intelligence recognition accuracy rate is a false proposition at this stage " is that there are three reasons:
1. The numbers given by many manufacturers have not been verified by authoritative organizations;
2. The recognition rate of artificial intelligence is actually updated every day, and it is impossible to give an absolute value;
3. Strictly speaking, there is no authoritative evaluation standard for artificial intelligence accuracy. There is only a public data set for the algorithm PK, and there are only tens of thousands to 100,000 images in this data set (similar to the English four-level real question bank). ), companies with ulterior motives will score points in the game, the pictures in the real scene are tens of millions, and the company applications with high scores can't really use the real scene!
Even with all the APIs of Microsoft's cognitive services that are recognized by ImageNet as the world's leading technology, the official will not give figures on accuracy.
Therefore, it is irresponsible to flaunt a so-called accuracy rate to boast the security of its own products. What's more, it's still the face that pays for this security level!
Want to make your face a password, you can choose a safer postureIt is undeniable that biometrics is indeed the trend of the times.
Mainly refers to a technology for identity authentication through human biometrics (such as fingerprints, faces, irises, etc.). Human biometrics are usually unique, measurable or automatically identifiable and verifiable, hereditary or lifelong ( Please ignore the characteristics of modern common face changes.
â–¼ Windows Hello, which emerged in the same year, is a multi-factor authentication solution using biometrics.
Windows Hello, you can detect your face, iris, and fingerprints; plus its good "oil" - Microsoft Passport, the two can provide multiple authentication to log in to your Windows 10 device.
To say Windows Hello, you must mention an infrared camera that supports Windows Hello, integrating Intel RealSense technology (RealSense 3D). It can detect images in high definition, detect heat and depth detection, and detect specific infrared light sources to ensure that the device can correctly recognize faces. It can also achieve iris recognition and verification method with higher precision and the most persistent biological characteristics.
Simply put is:
- For face or iris detection, Windows Hello can verify a living person through a combination of hardware and software with an infrared sensor - the depth sensor can create a "3D face model" for more than 70 sample points for your face, where High and low can be detected, thus eliminating photos and people trying to imitate you;
- In addition, the face without temperature can't be recognized. Even if someone hits your head with a 3D printer, it won't open!
The Microsoft Passport is a two-factor authen TIcaTIon (2FA) system that combines biometric information identification with a PIN code to provide a more secure protection for user devices.
