Chapter 84: I've Been Upset for a Long Time

When ordinary trace inspection is done for backlog fingerprints, after the results are obtained, they must be submitted to fingerprint experts for review.

Some provinces and cities have special organizations such as "Fingerprint Expert Committee" to do fingerprint review work. However, most of them feel that it is a waste of expert manpower, and they all adopt a model of collecting by special personnel, then assigning to experts to match, and then summarizing opinions, such as Shannan Province.

However, during the fingerprint battle, there is no need to take off pants to shit. All the people present are experts. Skipping these experts and looking for other experts is not only troublesome, but also raises everyone's doubts-Is it possible that my active participation in the battle organized by the provincial department has made my expert qualifications questioned.

At the same time, it is also to increase everyone's work fun and help everyone learn from each other. The fingerprint review during the fingerprint battle will be reviewed by the experts present.

Each time, as long as 11 experts complete the review and a majority vote "agrees to identify", the fingerprint comparison this time is considered successful. The fingerprint post of the provincial department can send a letter to the local criminal police team to organize personnel to arrest.

However, even if 11 experts have completed the review, the fingerprint match will still exist in the system, waiting for the review of other experts.

If subsequent experts continue to choose "agree to identify", or if the majority choose "agree to identify", it will not affect the subsequent operation of the fingerprint match. However, in the whole process, if someone chooses "identify and exclude", it is possible to enter a new round of discussion and judgment.

Because of this, the judgment of the option of "identify and exclude" must be very cautious, and only when there is strong confidence and judgment basis will someone choose it.

Li Zemin, the uncle next to Jiang Yuan, clicked on the system's message prompt as soon as possible. He has always entered the state late, and because of his age, he can't beat the young people, so he is used to slacking off in the first few days, and often starts to exert his strength three or four days after the fingerprint battle.

However, Li Zemin is still very concerned and curious about the identification of other fingerprint experts.

In the target fingerprint database of the fingerprint battle, any fingerprint is not simple. Most fingerprints are actually key fingerprints that have been read and compared by experts.

No county bureau would easily hand over the key fingerprints of a major case to the provincial department without multiple attempts.

And the experts in the fingerprint battle are naturally not easy to deal with.

As the best in the province in the field of trace detection, the experts who have accumulated a lot of experience and professional skills will first choose the method they are best at, select the fingerprints that are most likely to be successfully matched, and then spend several hours or even days trying to match the fingerprints.

Most fingerprint experts can complete one or two such matches in the 14 days of a fingerprint battle, which is considered relatively successful.

And in order to complete such a match, fingerprint experts naturally have to use all their skills.

What Li Zemin likes to see most is these colleagues around him, who use all their strength and pretend to be nothing.

In the system message, there are a total of 12 prompts, representing 12 cases of fingerprints that have been cracked.

Li Zemin has agreed with all the previous 11. There is nothing much to say. The first batch of completed fingerprints were carefully studied and self-checked by experts. Few people are willing to spend a long time to achieve someone else's "identification and exclusion".

And the latest system message, clicked, the two fingerprints that popped up, it was not unexpected for Li Zemin, a little judgment, can confirm that the two are the same.

Positive comparison is relatively easy, it is like asking an ordinary person to find two pigs that look the most similar from a group of pigs, which is naturally very difficult. But if you bring two pigs over and ask him if the two pigs look alike, most people can give a reliable answer.

Not to mention experts.

Li Zemin operated the mouse lightly and clicked "agree" on the latest system message.

Then, Li Zemin looked at the specific fingerprint information.

At this time, Li Zemin found that the signer of the "identification" of the fingerprint was Jiang Yuan next to him.

"Good guy, good luck." Li Zemin muttered, and then continued to look at the fingerprint.

The first thing Li Zemin saw was the quadrilateral fingerprint structure. He smiled unconsciously and praised Jiang Yuan's luck again.

However, when he saw the details of the feature points of the two fingerprints, Li Zemin's brows couldn't help but frown.

Good guy, good guy...

Li Zemin couldn't help but turn his head and look at Jiang Yuan, saying: "Isn't this fingerprint matching you made by software?"

The matching of software systems has its own rules. The most basic principle is the matching of a certain number of feature points. A more advanced one can be a scoring system, and the one who reaches a certain score will be released.

But Li Zemin looked at the two fingerprints, and they couldn't even match the feature points when put together.

However, from the perspective of human standards, or in other words, not simply comparing feature points, but comparing structures such as points, lines, and surfaces, it is indeed possible to identify the same.

This can be said to be a very honest way of fingerprint matching. In the era when there was no automatic matching of computer systems, everyone used a similar method.

It's just that it is even rarer now.

Jiang Yuan's eyes were fixed on the screen, and while operating the mouse, he said: "I was looking at other fingerprints, and suddenly saw it, pulled it over and compared it, and it matched."

"Then you remember fingerprints very well." Li Zemin smiled. He understood what Jiang Yuan said. It was normal to compare fingerprints with quadrilateral structures occasionally.

But if we really talk about fingerprint structure, such a small fingerprint, one centimeter square area, in addition to quadrilateral fingerprints, there may be pentagonal, hexagonal, circular and other structures. You must have a deep memory of fingerprints to do this.

"Lucky." Jiang Yuan responded, very social.

Li Zemin laughed and pointed at Jiang Yuan with his hand, saying: "This is good. You have come to the fingerprint battle at such a young age, and you have already achieved a victory. There is no pressure next. The pressure is given to us old men."

While he was talking, someone else agreed with Jiang Yuan's "identification". The "Ranking of Backlog Cases Solved" on the wall in front of the office was immediately updated.

Jiang Yuan's name rose by more than 20 people in one breath and came to the middle position.

And on his right side, there was a "1" at the battle result.

Li Zemin's name was still behind, and there was only a "0" at the battle result, but he was not in a hurry. From 0 to 1, it was never difficult.

Li Zemin even had time to continue looking through the cases that had just been identified as the same.

"It was the rape case of an underage girl in Miaohe County. This person committed three crimes. I think he's a little familiar!" Li Zemin took a breath and shouted.

Many people looked over, but most of them were just touched by the noise. Among the backlog of cases accumulated by the provincial department, there are many major cases, and people's memory is always limited.

However, there was a trace inspector from Miaohe County in the office. He stood up and walked over to ask, "Did you crack 515?"

"It wasn't me. Jiang Yuan was the one who got it right. He's from Ningtai County Bureau, right?" Li Zemin stepped aside and introduced Jiang Yuan, "Qian Mingyu is a fingerprint expert from Miaohe County and has 20 years of police experience."

"20 years is useless. I've been following the 515 case for several years. The three victims were all middle school students. After the case happened, their parents came to our bureau many times. Later, the victims couldn't stay in the county anymore and moved away one after another. They would occasionally call to ask..." Qian Mingyu was slightly younger than Li Zemin and sighed at this time.

Jiang Yuan said straightforwardly, "I encountered a quadrilateral fingerprint. After comparing, it was determined to be the same."

"Let me see, where are you from?" Qian Mingyu was more familiar with Li Zemin and looked directly at his computer.

Li Zemin gave up his seat, took a look and said, "Wanxiang City is a bit far away."

Wanxiang City and Miaohe County, one in the west and one in the east, straddle the border of Shannan Province.

Qian Mingyu said "yes" heavily, nodded to Jiang Yuan, took out his cell phone and said, "I'll tell our captain that this case has been a problem in our county for a long time."
