With photos, you can open the Fengchao cabinet, take photos secretly, and open the express cabinet
However, recently, the curiosity laboratory received a report from the science team of class 402 of shangwai Xiuzhou foreign language school (located in Xiuzhou District, Jiaxing, Zhejiang Province), saying that it could deceive Fengchao cabinet with only one photo. is that true?
Brush face to receive express delivery, first open the brush face pick-up function of the account, first scan the code to enter the applet, and then click for identity verification. After passing, you can experiment
Dashi (the experimenter) took a large head photo and printed it in color. It was A4 paper size, similar to the size of a normal face.
Before the experiment, Dashi bought himself a lot of express, all of which were stored in the Fengchao cabinet. Next, Dashi didn't need to take a piece of code or brush his face. He just brushed the photos to see if he could take them out.
On site Dashi hid his body to prevent the camera of Fengchao cabinet from sweeping his face. Aim the photo at the camera for one second and the recognition is successful. Dashi tried five times in a row, and all of them were successfully opened four times. One failure was because the photos were not stable.
The system displays that you want to enter the last 4 digits of the mobile phone for authentication. At present, the problem of information leakage is serious. It is not difficult to obtain the tail number of mobile phone.
Can I still open the cabinet door if I replace the self photographing of my face with the photographing of my face? Dashi used telephoto to 'secretly take' a photo, which is also printed in A4 size color. Unexpectedly, the Fengchao cabinet was opened again.
In fact, when the camera collects faces, it forms only a 2D plane image, which is equivalent to a photo. When you brush your face, it is the same as brushing photos for the system, and you can open the cabinet door.
Is there a safe face recognition technology?
The answer is yes!
At present, face recognition technology can be divided into two categories: 2D face image and 3D face image. 2D face recognition only takes plane imaging through 2D camera, so even if the algorithm and software are more advanced, the security level is not high enough under limited information, and it is easy to be cracked through photos.
The real high security level is 3D face recognition system. It has three-dimensional imaging through 3D cameras. Generally, there are four probes, of which two are large cameras, the other two are infrared probes for light supplement, and the other is visible light probes. The two cameras cooperate with each other to form 3D images, so as to restore the complete three-dimensional world. In short, with more information obtained by the machine, the accuracy of analysis and judgment is improved. At present, 3D face recognition technology can accurately distinguish photos, videos, masks and twins.
In October 14th tiktok, the video of tiktok, was clicked about 6400000, and more than 150 thousand points were praised.
On October 15, the official voice of Fengchao smart cabinet:
With regard to the feedback on the "face brushing" problem received recently, our company verified and communicated at the first time. As the beta version of the trial operation is currently undergoing a small-scale test, we have received feedback from department users to identify the problem. It is now offline and is expected to consider going online after the function is improved. Thank you for your attention and support to Fengchao.
