Chapter 83 Determining the Same
Changyang City.

The scorching sun was in the sky, the traffic was rolling, the smooth black silk was wandering all over the street, and the long white legs were swinging back and forth.

Jiang Yuan opened his eyes, got up from the hard plank bed, and waited for a few seconds before realizing that he had already lived in the guest house of the Provincial Department.

Open the curtains, outside is a lush green plant, showing a beautiful picture of being willing to water.

Jiang Yuan stretched, folded the quilt slowly, and washed and dressed at an even slower speed.

After coming to Changyang City and participating in the "Provincial Fingerprint Information Cracking Competition" for two days, Jiang Yuan already knew that laziness in the morning was the most relaxing moment of the day, almost the only relaxing moment.

When he walked out of this door, he would hold his head up high and maintain a police demeanor.As for the office, it was another kind of terrifying casualness.

You can eat whatever you want, drink whatever you want, dress whatever you want, shout whatever you want, as long as you can match the kind of randomness you get in your fingerprints.

More than 30 trace inspectors from all over the province and states gathered together, and they were very involved.Each person has seen [-] fingerprints per day, which is considered to have reached the average line.

Zhu Huanguang, a policeman from Changyang City, is the king of fingerprints in this province. He sees more than 6000 fingerprints on a daily basis, which is unbelievable to the layman.

In fact, Zhu Huanguang is able to look at fingerprints for 14 hours a day, with an average of 500 fingerprints per hour, which is equivalent to looking at 8 fingerprints per minute, and each fingerprint is only observed for about 8 seconds.

And under this intensity, he has cracked 4 cases from other cities and counties.

According to tradition, or in other words, according to the normal development law of fingerprint crime solving battles, with the passage of time, the number of solved cases must be more and more.Because the fingerprint experts' familiarity with fingerprints will gradually increase, and the later, more and more cases will be cracked.

This is also the reason why the fingerprint crime solving battle is constantly being promoted.

In the past, fingerprint experts worked on their own in each unit, and from time to time they did chores that ordinary colleagues in the unit could do—such as holding meetings.Can't concentrate on the comparison of fingerprints.

Fingerprint battles are different.

During the fingerprint battle, the provinces, departments or ministries and commissions will provide food and lodging, round-trip fees, and business trip subsidies. They will bring fingerprint experts from all over the country. If there is nothing wrong, they will compare fingerprints every day, so as to concentrate on accumulating familiarity with fingerprints. , constantly increasing the probability of solving the case...

The fingerprint experts are also very happy. They are all 40-[-] years old. They sleep in the dormitory, eat in the cafeteria, and don’t worry about whether their wives are happy or not, or whether their children’s homework is written or not, and they don’t have to worry about whether their parents are arguing or not. , not to mention the facial expressions of the leaders and the careful thoughts of colleagues, what we have to face every day are dozens of familiar and unfamiliar faces, hundreds of familiar and unfamiliar fingerprints, and the "ranking list of solved cases" on the wall. I don't know how comfortable it is.

And the reason why there is a time limit for such a suitable matter is mainly because the provincial department is worried that the experts will be exhausted.

Of course, the status and efficiency of the experts are also different.For example, Jiang Yuan, on the "Accumulated Cases Solved Ranking List" hanging in the office, behind Jiang Yuan's name, the number of accumulated cases solved is clearly 0, and together with more than a dozen other trace inspections, it is tied for the bottom one.

However, Jiang Yuan didn't appear to be in a hurry. When he got to the office, he made himself a cup of tea first, and then looked around.

Comrade Zhu Huanguang was scrolling, and the fingerprints on the computer screen were being swiped.The lesbian next to me is injecting eye drops for herself.The fat colleague next to him is eating big cakes, and the screen in front of him is also getting his fingerprints swiped.

To be honest, the state of this office looks like a self-study room for the college entrance examination, the kind of over-aged.

"Xiaojiang, you haven't broken zero yet, don't you worry?" The uncle at the next station looked over with a smile.

He rubbed Jiang Yuan half a box of Zhonghua yesterday, and he became irresistible.

Jiang Yuan smiled, turned his head and said, "Didn't you break zero?"

"I'm used to it." The uncle smiled and said, "Wait for a while."

"Then I'll hurry up and take two steps." Jiang Yuan finished his daily courtesy work, turned around and stared at the screen.

Soon, in the self-study room...no, in the office of the "Provincial Fingerprint Information Cracking Campaign", only the sound of typing on the keyboard and mouse was left.

Jiang Yuan leaned back on the chair, staring at the computer screen, drawing feature points once, and looking at many fingerprints.

The fingerprint comparison during the fingerprint battle is completely different from the daily fingerprint comparison.First of all, the fingerprints that can be selected for the fingerprint battle are all selected from various places, and there are quantity restrictions, quota restrictions, and an entry and exit mechanism.

To put it simply, small cases are not required, and those that have not been settled over time are not required, and those that have not been matched many times by their own trace inspections are not required.

Therefore, the fingerprints that enter the fingerprint battle are either the fingerprints of major and serious cases, or the fingerprints of difficult and difficult ones.For some fingerprints, there may be one-fifth, or even one-sixth of the normal fingerprints, and we still need to try to match them.

For these difficult fingerprints, it is meaningless to trust the fingerprint matching system.

This kind of thing that ordinary trace inspection will do, there is no need to fill out various reports and submit them to experts for processing.

Because of this, when the fingerprint experts in the office are faced with difficult fingerprints, the number of candidate fingerprints is directly placed at 200 or even more than 300.

It is equivalent to maximizing the role of people, or in other words, the workload of people.

Experts snapped past fingerprints. In the past, they might have been screened out with software, but now they are all re-passed by manpower, and it has to be the most advanced manpower in trace identification.

But that's not the case. With normal use of the software system, most of the backlogs are impossible to compare.

This is also one of the great differences between criminal investigation technology and ordinary technology.Ordinary technology may pay more attention to cost performance, and is willing to give up part of the functionality to ensure cost and benefit.

Criminal investigation technology also requires cost, as well as input and output, but at some point, criminal investigation would rather spend tens of thousands of dollars than solve the case at any cost.

This logical conflict has troubled experts from the very beginning.

However, this trouble did not affect Jiang Yuan.

He just wanted to simply match the fingerprints, and that's exactly what he did.

At this time, a parallelogram-like fingerprint passed Jiang Yuan's eyes.

In Jiang Yuan's mind, a fingerprint that he saw yesterday immediately appeared.

The fingerprint I saw yesterday has a similar parallelogram shape, which is also a very rare fingerprint shape, and it is held by a very rare perverted rapist.

Although, the fingerprint just swiped has nothing to do with the fingerprint seen yesterday in the software system - it appeared because Jiang Yuan compared a robbery case.

However, Jiang Yuan's first thought was to combine the two and compare them manually.

Both fingerprints are very blurred.

Although to the human eye, both have a very obvious parallelogram shape structure, but the software system obviously does not think so. Just looking at the grooves, dots, and warps inside, the overlap between the two is less than 30%.

But the trend of ridges is consistent.

It shows that one of the fingerprints is just blurred to the key point, and may have serious deformation, and at the same time, the other fingerprint may also be the same.

Jiang Yuan thought while comparing, and after confirming again and again, he clicked the right mouse button on the right side and made a mark: identify the same.

In every corner of the office, there was an endless "ding dong" sound.

The experts present who didn't turn off the reminder all got a new news from this, that someone identified a certain fingerprint as the same.
