Warm marriage to the bone, the president's wife is ruthless

Chapter 351 Face Pattern Lock

"Go and sit in the car for a while..." Song Yanshu had a strange expression, and opened the car door for Mu Qingqing.

As soon as he got in the car, Song Yanshu turned up the heater, and the whole atmosphere was awkward.Mu Qingqing felt very stuffy, so she stretched out her hand and turned off the warm air. It's just the weather in early autumn. Although it was getting cooler at night, it wasn't enough to turn on the warm air.Within a minute, a thin layer of sweat had already oozed from Mu Qingqing's forehead.

Before Song Yanshu could speak, there was a sound of a car coming from the gate, it was Cheng Qi who had returned.Seeing Cheng Qi's car driving into the yard, Mu Qingqing opened the door and got out of the car, and Song Yanshu followed behind.

"You..." Cheng Qi felt a little strange seeing Mu Qingqing and Song Yanshu at the door.The first is why Mu Qingqing didn't go in, and the second is why Song Yanshu came back with Mu Qingqing.

It was only later that I learned that Mu Qingqing did not bring the key, but when he heard the news, Cheng Qi couldn't help laughing. When he locked the car door and walked to the door of the villa, in front of Mu Qingqing and Song Yanshu's face opened the door.

"So you didn't lock the door..." Mu Qingqing exclaimed, then shook her head and laughed, Song Yanshu also looked helpless.

Cheng Qi seemed to be interested, he deliberately closed the door and opened it, repeating several times.Then when Song Yanshu tried it, the door was locked and couldn't be opened at all.But Cheng Qi obviously didn't use the key just now, the door was also closed, how could Cheng Qi open it but Song Yanshu couldn't.

"Fingerprint lock?" Song Yanshu asked.

This time, Cheng Qi was proud of himself. He pointed to the seemingly ordinary door lock and said, "Fingerprint locks are not safe at all. It is easier to steal fingerprints than to steal keys. It has always been used to guard against gentlemen but not villains. pointless."

"Look here..." As he spoke, Cheng Qi pointed to a very tiny black spot on the gate, which was only about one-third the size of a black sesame seed.

"This is a facial recognition system. It uses a computer system for comparison, face tracking and detection, automatic image size adjustment and infrared heat detection. It is considered to be a relatively advanced biometric technology abroad, but it is still immature. It is considered to be in the research and development stage. .Mainly through the comparison of irrelevant video streams, I adjusted it, it is enough for personal use.”

In this regard, he is an expert at the expert level, and he can't stop talking about things in his professional field, with proud pride in his eyes.

Immediately, he waved his hand to Song Yanshu, who was bewildered, and asked him to give it a try.Sure enough, when Song Yanshu was standing in front of the door, there was no way to open the lock no matter what.

"When did you change this strange system, but my key can also open this door. If someone steals the key, isn't it safe?" Mu Qingqing had no idea that Cheng Qi's door was still hidden like this high-tech.

Cheng Qi coughed twice, and said with some embarrassment, "Qingqing, in fact, you don't need to bring the key next time, because in fact, every time you open the door, it is not the key that plays the role, the key is actually in the door lock. It's spinning around in circles."

"What?" Mu Qingqing couldn't help being taken aback, feeling as if she had been tricked, "You mean, when I opened the door before, you set up facial recognition early in the morning. That is, every time I worked hard in the bag When you turned the key inside, the door had already been opened?"

Cheng Qi nodded, before Mu Qingqing lost his temper, he invited everyone into the room.

"Okay, you Cheng Qi, how dare you play tricks on me!"

Mu Qingqing took a sip of water and asked, "Then how did you sample it? I don't seem to have cooperated with you?"

"It's actually very simple. First, just create a facial file, which is enough to help me complete the sampling!" Cheng Qi pointed to a small surveillance camera at the entrance of the living room, and then said, "The facial image file will generate a facial pattern encoding , stored in the server."

"Like a fingerprint?" Song Yanshu interrupted while sitting on the sofa.

"Well, you can say that's right." Cheng Kei nodded, and then said, "But photos are not acceptable, they must be three-dimensional portraits. The facial patterns that have been recorded in the server will become a source data for comparison, which will be identified and compared by the system More than 100 kinds of data such as face, skin tone, facial expression and posture, etc.

It will probably be completed in about five seconds. At present, the biggest problem for foreign research teams is this insurmountable five-second barrier. They strive for real-time performance, and the difference cannot exceed half a second to be perfect, so they have not been put into use.

But our family is different. These five seconds are too easy to be digested by some people's confusion, so I used it conveniently. "

Mu Qingqing remembered her habit, it was precisely because she liked to misplace the keys every time, so the difference of five seconds was never discovered, because those five seconds were not even enough time to find the keys, The door lock has already been opened.When Mu Qingqing took out the key from her bag, she made a useless gesture.

Thinking of this, Mu Qingqing couldn't help but glared at Cheng Qi.

Song Yanshu was very interested in what Cheng Qi said, and asked, "Then how did you get this technology? As far as I know, our country's current development in this field is still zero."

Cheng Qixie smiled and said, "It's not important. The important thing is that I have successfully reduced the difference of five seconds to three seconds, but it is still unstable and needs to be tested. The current biometric technology in China is mainly questioning. And iris, in fact, it is enough for smart home applications, but when it comes to security, the whole level is lowered.”

"It seems that your company is only two seconds away from going public, right?" Song Yanshu looked at Cheng Qi with deep eyes. He always looked at Cheng Qi differently, but he didn't think that his ability is really inestimable.

"Ah?" Mu Qingqing looked at Cheng Qi and Song Yanshu blankly, Mu Qingqing didn't understand such professional and technical matters at all.If someone asked her what her company's main business and content are, Mu Qingqing probably wouldn't give a perfect answer.

It's just that all of this is under the control of Cheng Qi. In just seven or eight years, Cheng Qi has been able to turn a small company with a registered capital of less than 100 million into a large-scale company with a market value of over [-] million. For the business world, it is all about showing your sharpness.

However, because Cheng Kei has been very low-key in the past few years, he has not received as much attention in the public eye as others.
