Chapter 752: Vulnerabilities in the Sky Eye System after the upgrade
can become the director of the international airport police station, Director Wang naturally knows how to choose.
Xu Zheng and Jin Ze looked young, but both of them were leaders of the ministry's pursuit bureau, and when it came to this, he called his leader again, which is to look down on others.
Although work comes first, and he is also the first person responsible for something, but now, there is not much time for him to think about it.
Chen Yuanwen is the person who pursues the escape system, and he has been praising Xu Zheng just now, but now he is a little unreasonable when he keeps his mouth shut, "Wang, Director Xu's simulation portrait ability can be said to be the top existence in China now, you..."
Director Wang was very decisive this time, and immediately pleaded with Xu Zheng, "Without further ado, Director Xu also asks you to work hard and go to the cabin with me."
Xu Zheng naturally did not refuse, helping the airport police station, but also helping himself.
Soon, accompanied by the general manager of the airline, the group went all the way to the green light and went straight to the plane that was about to take off.
It's just that the general manager of Zhengding Airport, the airline, according to the system, only let the police send two people up, plus two security personnel of their company, after getting on the plane, they must also be under the supervision of their captain before they can work.
Xu Zheng was not interested in these negotiation trivialities, and it was not his turn to participate.
But if he goes to the cabin, he must wear a police uniform.
Yes, Director Wang temporarily found a set for him, "Director Xu, once you wear this police uniform, you can completely use it as a propaganda signboard for our police."
What the police force wants is righteousness and heroism, with a vague iron and evil spirit, and as for serving the people, that is a slogan.
Xu Zhenggang has experienced the attack on the Xu family, and the evil aura on his body has not yet dissipated, and everyone present is an old policeman, and he can almost feel it.
"The king praised it falsely, if this police uniform can make all criminals take the initiative to appear, that is the highest glory of our police."
Listening to Xu Zheng's modesty, Director Wang, an old policeman in his forties, smiled and did not answer, as long as he was a wanted criminal, he was a criminal who escaped from the police.
They have all fled, and there are really not many people who can turn themselves in.
As the two spoke, they boarded the plane with the airline's security personnel, and the cabin was full of passengers, all waiting for the plane to take off in a few minutes.
At this time, seeing the ground staff, as well as two police officers, boarded the plane, the passengers realized that something special must be the case.
At this time, the chief and two flight attendants greeted them, and they received the information that they were only cooperating with the police, but they did not know what the police were going to do.
Director Wang approached the captain and whispered, "Please take us to the business class, be fast, and not attract the attention of the people inside."
The captain in a white shirt and a white hat was obviously experienced, and his face was natural, so he just nodded, then turned around and walked towards the business class with Director Wang and Xu Zheng.
A few people just walked to the business class, and the passengers here are also accustomed to looking over.
Including Xu Zheng's target for them, the Caucasian man with brown hair and brown eyes.
Director Wang was naturally an experienced veteran policeman, and he glanced sideways at Xu Zheng.
Xu Zheng is now less than three meters away from the target person, and at such a close distance, his eyes are like X-rays, directly scanning the target person.
With his current master-level mock portrait and skull restorer, coupled with the study of skulls, he could recognize at a glance that this was the person they were looking for.
What's more, this target figure saw that there were suddenly two more policemen in the cabin, and a trace of panic flashed in his eyes.
Director Wang saw Xu Zheng nodding, and the heart hanging in his throat dropped a point.
He has so much experience in arresting that he quietly continued to follow the captain forward, and when he was about to walk in front of the target, he came by surprise.
But the target is not a dry meal, he is a person who can be the deputy mayor, and vaguely feels that the police are here to arrest him.
Before Director Wang and Xu Zheng could walk to him, he suddenly came out of the cage like a fierce tiger, stretched out two sharp claws, and grabbed at the neck of a beautiful young woman beside him.
Obviously, he wants to find a hostage and make things bigger, as long as the plane takes off, the chaos is big, and the international impact is caused, then he has a chance to escape...
The young woman did not feel in danger at this time, because she, like other ordinary passengers, was looking back at the two policemen in police uniforms.
Wondering what they are doing in the cabin.
The woman didn't realize that the person next to her was going to take her hostage, but Director Wang and Xu Zheng could see it clearly.
This arrest operation is naturally to avoid all kinds of influences, especially in this cabin, many of whom are international friends.
The above requires that attention should be paid to the impact when arresting.
If the target person captures the hostage, the impact will be great.
Director Wang instinctively wanted to run over to stop him, but a figure suddenly flashed in front of him.
In the blink of an eye, the shadow was already in front of the target.
Director Wang was startled and calmed down, only to realize that it was the figure just now that turned out to be Director Xu.
I saw Xu Zheng quickly flashing to the young woman, as if greeting someone, and holding the target's hands tightly.
He also said enthusiastically: "Mr. Xing, we have found you, thank you for helping our police find an important suspect."
Now we ask you to be a witness, and we hope that you will cooperate with us..."
At this time, the target looked at the policeman holding his hands in shock, as if to say, why are you so fast?
Seeing that he couldn't catch the hostages now, and he was still grabbed by the police, the target was desperate, but he still wanted to save himself, gritted his teeth and said calmly:
「Please,youdoing?」
When Xu Zheng heard this, he almost laughed, and leaned close to the target person's ear and whispered, "Vice Xing City, leave yourself a decent face, right?"
"You..." Vice Xing stared, but under Xu Zheng's gaze, he was like a deflated ball in an instant, and he didn't dare to stand up anymore.
At this time, Director Wang squeezed over, and he heard the conversation between the target and Xu Zheng, so it fell to the heart under his throat, and this time, it finally fell back to its original place.
But he was still a little uneasy.
When I walked up to the target, I reached out and touched someone's neck, face, and arms... It took him a while to stop this seemingly dirty behavior.
Because he was already 100% sure that the target was indeed wearing a 3D hood and a human skin suit.
This kind of skin cultured by real cells is naturally the same as real human skin, and it is definitely not enough to touch it alone, but you have to twist and rub it vigorously to form non-standard folds to prove the difference between the human skin suit and the target's own skin.
Coupled with the conversation between Xu Zheng and the two just now, and what the target person did, he now fully believes that the Caucasian in front of him is the Xing Vice City that his superiors asked him to intercept.
After determining the target person, Director Wang nodded to the captain and the security personnel who came with him, and then the group prepared to escort the target person to get off the plane first.
It's just that the woman Xu Zheng rescued just now stretched out her hand to stop him, "I'm sorry, excuse me, comrade police, is this person a fraudster, he just said that he is a professor at some university in a beautiful country..."
"I'm sorry ma'am, this is a confidential case, no comment!" Xu Zheng had the heart to scold her for being brain-dead, and she couldn't see such an obvious thing.
But in line with professional ethics, I replied to her in accordance with the police regulations.
Although the young woman didn't have eyesight, she could also hear the coldness in Xu Zheng's words, she pursed her lips disdainfully, and muttered in a low voice, "If you don't say it, you won't say it, what kind of hanging..."
Xu Zheng was speechless, but he didn't bother to bother with this kind of person.
Everyone got off the plane, and as soon as they got out of the runway of the plane, Instructor Zhao of the police station in front of the station personally drove a commuter car over, and he couldn't wait to ask before he got off the car:
"How's it going, are you sure?"
Director Wang nodded, and after the car stopped, he and Xu Zheng escorted the target into the back seat of the car.
Go back to the office first, but don't enter the compound, park it outside.
We don't have to worry about the rest.
This man, someone will come and take him away."
Xu Zheng didn't pay attention to the discussion between Director Wang and Instructor Zhao at this time, and he didn't care about the pitiful appearance of Deputy Xing Hall next to him.
He is analyzing the comparative values of the Tianyan system, whether to adjust it downwards.
The arrest operation just now has fully proved that as long as the wanted criminal wears a 3D head covering, which is different from his real skull data, it can affect the screening and comparison results of the Tianyan system.
For this kind of wanted criminal, Xu Zheng currently has only one suggestion, and that is to lower the comparison value.
Talk about 60% to 40%.
These people who take advantage of the loopholes, put on a 3D hood, and then cover the scalp with something inside, and the results of the Sky Eye system scan are definitely not real.
In response to this situation, the Sky Eye system compares the value of the wanted criminal's skull based on the results of scanning their faces.
There must be some errors in this, and the specific number of reductions is still up to the leaders to decide.
In addition to this situation, Xu Zheng felt that the new skull modeling function of the Tianyan system still needed to be improved.
But how to improve, he can only propose a rough range, because the ministry has not yet established a completed skull database, and without the support of big data, there is naturally no way to correct it.
Everyone returned to the police station in front of the airport station, Director Wang and Instructor Zhao also finished their work, they were in a good mood at this time, and after thanking Xu Zheng, they proposed to continue to carry out the follow-up experiments.
Now at three o'clock in the afternoon, there is still a lot of time before getting off work, Xu Zheng also wants to verify it again, and the value he just considered naturally agreed.
"Director Wang, can you please lower the contrast value of the skull scan of the Tianyan system in the background, to 40% first?"
Director Wang was a little confused about what Xu Zheng wanted to do, the background of the Tianyan system is generally in the hands of the Municipal Science and Technology and Information Detachment, but their airport police station is now temporarily cooperating with the national action of the ministry.
It has the permission to temporarily modify the background data of the SkyBit system within the airport area.
"Naturally, there is no problem in modifying the value, but if you lower it to 40%, then the error rate will increase, and our tasks will increase a lot..."
Xu Zheng touched his chin and pondered again, "I can only say that I have to work hard, brothers, if I don't lower it, I may miss those wanted criminals who have been prepared for a long time.
It's like Vice Xing City just now."
When Director Wang heard Xu Zheng's answer, he knew that the young man in front of him had already made a decision, he himself cooperated with the experiment, and he had helped so much just now.
He nodded directly in agreement, "Okay, I'll have someone modify the background data now."
As Director Wang went out to call, Jin Ze and Chen Yuanwen hurriedly asked Xu Zheng for the detailed reasons for doing so.
Xu Zheng didn't hide it, so he told the two of them about his concerns just now, and finally concluded: "Reducing the data value and increasing the error rate have the disadvantage of increasing the work of colleagues.
The most difficult, of course, is the pressure of leadership.
After all, as soon as the error rate rises, there will be more people who catch the wrong one, and those who catch the wrong one will definitely complain.
Regardless of the outcome of the complaint, there will inevitably be many complainants."
Jin Ze smiled, "Xiao Xu, you haven't changed your way of thinking, you are working in the ministry now, what can they complain about, as long as you can do the right thing and do good things, the leaders above will also support us."
Xu Zheng was stunned, thinking about Jin Ze's words, it was really the case, the higher-level units of the ministry but..."Since this is the case, then let's rest assured and boldly experiment.
Let's see if 40% can be screened out of wanted criminals.
If it doesn't work, it's going to be 30 percent, 20 percent..."
Chen Yuanwen stroked his palms and laughed, feeling that Xu Zheng, a young man, really lived up to his reputation, his brain reacted quickly, and he dared to admit his previous mistakes, "This proposal is good, but I think 40% is about the same.
Further down, the error rate is higher.
There are more people who are caught wrong, and our local comrades will be too busy to do so."
While the three of them were talking, Director Wang hung up the phone and walked in, nodding at Xu Zheng, indicating that the background data had been modified.
Although the values have been revised, it does not mean that the Sky Eye system can immediately screen out wanted criminals.
As the minutes ticked by, ten minutes... Thirty minutes... One hour.... Two hours later, the Tianyan system, whose comparison value had dropped to 40%, still did not screen out a single wanted criminal.
Just when Chen Yuanwen and the others were disappointed, the Tianyan system screened out, and the prompt sound of successful comparison finally sounded.
A B-class wanted criminal issued by Bac Ha province was photographed on his face and entire head by a camera in a parking lot near Zhengding International Airport.
Then the Tianyan system automatically compares the result to 46%, which causes a system alarm.
As soon as the alarm sounded, Xu Zheng immediately asked the map detectives organized by the airport police station to monitor the A2 parking lot in real time and monitor all the movements of the person suspected of being a wanted criminal.
Soon, the investigators found the suspected wanted criminals screened out this time according to the location locked by the Sky Eye system.
A beautiful woman with a slender figure in a black dress and a sunhat.
In the video, she gets out of a car, picks up the charging gun, and prepares to charge her car.
The camera just captured her face, and she still didn't wear a hat, but in the video, the woman's appearance is not the same as the photo of the wanted warrant.
The scanned skull comparison value is only 46%, so it can be said that if it is left in the Changming May Day operation, it will be directly ignored by the Tianyan system.
Seeing this situation, Director Wang glanced at Xu Zheng with some hesitation, "Director Xu, you say, do you want to catch it?"
Xu Zheng heard that Director Wang was supporting him now, so he smiled and said, "Naturally, it's arrested, no, it's not certain that this woman is a suspect yet, so let our colleagues ask her to come to the police station to assist in the investigation."
"That's the right reason, then I'll inform my colleagues outside." Director Wang made a phone call, and soon the police near the parking lot rushed over.
Xu Zheng and the others could clearly see through the cameras arranged in the parking lot that two police officers and two airport security personnel drove a commuter car to the woman who was suspected of being a wanted criminal.
It is obvious that this woman is very nervous, she even forgot that her car is charging, and actually made the action of putting the gear on the brake and stepping on the accelerator....
