Defect another world

Chapter 438 Find!
Just thinking about it in his head, Li Huo felt that the data in his brain was overloaded.
"Even if we can find their camera records, it doesn't make any sense. They have already changed their faces and hid in the vast sea of ​​people. What's the use?"

"it works."

Meng Fei opened the Goddess system, selected Qingqing, and then clicked on the projection screen, unceremoniously overlaying Li Huo's PPT on the big screen.

But in the thrill of being about to catch a turtle in the urn, Meng Fei suddenly felt his nerves tense, and he yelled in his heart that something was wrong!

He forgot the occasion in a moment of excitement, and directly cast the chat window with Qingqing.But Ai Ting was still watching from the sidelines.

Even if Ai Ting is not around, if those ambiguous chats with an AI who said "wife" are displayed in front of everyone, everyone will think that he is smart, right?

But I have already clicked on the projection screen, and it is too late to retract it.

Sweating profusely, he glanced at the big screen, only then did he realize that all the chat records between himself and Qingqing had been deleted?
The interface is clean, only the simple and clear greetings from the goddess AI.

"Mr. Chief Investigator, hello. I am the goddess AI system, how can I help you?"

Meng Fei breathed a sigh of relief and thought to himself:
"She actually knew that I tapped the screencast? Of course, of course she knew. I tapped the screencast on the Goddess app, how could she not know? Fortunately, the AI ​​​​responses quickly, otherwise it will be over."

Wiping the sweat that broke out on his forehead, Meng Fei entered seriously: "I want to check the records of all Chiwu people who entered Wutong Customs in the past six months."

"The case under your name has been confirmed. The Twelve Nightmare case is selected by default. If confirmed, please reply yes, if not, please reply no."

"Yes."

"These materials can only be used for your investigation of the case, and cannot be disclosed to anyone outside the task force.

"If there is any violation, you will violate the "Personal Information Confidentiality Law" and bear corresponding legal responsibilities. Do you fully understand this?"

"learn."

Meng Fei frowned while typing patiently, thinking it was really troublesome.When did Qingqing become so troublesome?

Didn't you just say the word "wife" in the key and give you whatever you want?

"58791 records have been queried. Do you need to filter?"

"First check to see if any of these immigrants have the same appearance as Wan Yi, Wu Jun, and Liu Jian?"

After about three seconds of comparison, the goddess replied unsurprisingly: "No".

Li Huo showed a helpless expression and said:
"Look, I've said it all, even if these three dolls did enter the country in this way, but they were mixed among the 5 people and changed their faces, how do you find them out?"

"Well, but I don't have to find all three. Just one."

Meng Fei tapped on the table and said to Li Huo:

"First of all, Chiwu people come to Wutong City, most of them are for short-term tourism, a small part of them are for business, and there are not many people visiting relatives and emigrating.

"Travel and business will not stay for too long. If you exclude those who have returned to China or have traveled many times, you can exclude a large number of people."

"Then the face of the doll is easy to change, but it is not easy to change the gender and height. Let's assume that their gender and body will not change.

"Then among these three people, Wan Yi should be the one with the most obvious characteristics. First of all, all men can be excluded.

"Then she's shorter and thinner, and women who don't qualify can also be excluded.

"After so many rounds of screening, maybe a few people can be selected accurately, and then they can be confirmed one by one at the end."

Then he entered the text: "Screen, exclude those who have already left the country and those who have entered the country many times."

AI replied: "It has been excluded, and there are 4821 records remaining. Do you need to continue screening?"

He guessed right.Just excluding those who have already returned to Chiwu and those who have gone back and come back again, [-] to [-]% of them are excluded!
"Exclude men and only choose women." Meng Fei entered again.

"Men's records have been excluded. There are still 1320 records left. Do you need to continue screening?"

"Height 1.53, weight 42kg. Please exclude records that cannot meet these two conditions."

There will be no record of height and weight in the passport.However, there are video images recorded by cameras at entry and exit.

The artificial intelligence program can roughly estimate the height and weight of the person being photographed through the pictures taken by the camera.

Although it is impossible to be precise to the number of decimal places, it is possible to exclude people who are unlikely to meet the criteria.

"Screened based on height and weight requirements. 202 records remaining."

More than 5 records, only [-] left in the blink of an eye!Li Huo had to accept this efficiency, and couldn't help but start to doubt his IQ again. .

"Search the faces of these 202 people in the public surveillance video of Wutong City in the past two months. If you can find them, exclude them."

The streets and alleys of Wutong City are full of cameras, and of course they will take pictures of people's faces when they come and go.

In theory, if you perform face recognition on the faces that appear in the video, you will find out "who" has been "where".

This kind of data is the most sensitive "private" information of Xizhou people.Therefore, there are no cameras on the streets in many countries in Xizhou, and it is illegal to install a driving recorder in your car.

Qingmang adopts a compromise between public safety and personal privacy.Filming is to be filmed, but the state ensures that the data is not misused.You do not believe?Believe it or not is your freedom.

The result is that when Qingmang has basically eliminated such things as street robbery and petty theft, street robbery in more developed Western continent countries is commonplace.

"The calculation of face comparison is very heavy. But the level of this case can use the computing power of some countries' air computing power. Do you want to use it?"

Goddess AI reminded thoughtfully.

Wutong City has a population of about 2500 million.Assuming that 50% of people take to the streets every day, more than 1200 million faces will appear in a day's video.

In this way, compared with 200 faces, the amount of data comparison in a day is almost 20 billion times.

Completing a face comparison calculation in 1 second, it takes almost 20 years to complete these 60 billion comparisons.

If the server cluster that can be applied for by the Ability Bureau is used to complete 1000 face comparisons per second, it will take 20 days to complete the comparison.

"Need." Meng Fei said without hesitation.

After using the national air computer, the 20 days were shortened to 20 seconds.

After 20 seconds of silence, the text output by the Goddess AI appeared on the big screen.

"After face comparison, there are still 13 entry records left. Among them, 9 entries involve immigrants who have been determined to be outside Wutong City and can be excluded. There are 4 others, and the information is as follows."

The big screen displayed the information of four Chiwu women who entered Wutong City within half a year and have not left the country so far. They are about the same height and weight as Wan Yi, but have different faces!
