At that time, after the computer institute obtained the design principle and empirical formula of the pig system, they began to program the system according to the needs of the domestic police.

The domestic police pay special attention to the eight major crimes, especially the homicide cases. Therefore, in terms of the function of the pig system, it will definitely be biased towards this type of criminal eucalyptus and heavy eucalyptus, but not much attention will be paid to the economic eucalyptus.

Actually, I really want to say that this initial version is still too rudimentary.

As Li Yuan said in class before, the big data criminal investigation system also has many sub-projects. The big data system for different sub-projects should be designed separately to achieve the highest efficiency.

Stuff everything into it all at once? Then it becomes—everything can, and in the end nothing can be.

Of course, this is the initial version, and you can't be too demanding, so you can only leave it for later development.

Therefore, to solve the economic problems of CCB, in fact, the pig system is not very suitable. Fortunately, the computer has added a lot of function formulas to it, and with some parameters, it can be used even if it is so-so.

……

It didn't take long for all the data to be imported into the system. Li Yuan called several sets of function formulas, or did he calculate these data......

To put it simply, it's actually to pick out the abnormal data inside.

One thing to say, if it is a very ordinary anomaly, the bank will supervise and report it. No one would normally make such a low-level mistake. Even if you are an idiot and can't find a professional money laundering channel, wouldn't you be able to hire an accountant?

Therefore, the anomaly here is very hidden. On the face of it, it's completely legal. It takes the staff to pick from the large amount of data.

In fact, this is completely impossible. Let's say a medium-sized bank, how much money does they have in a day? With manual selection, you can't even see it all?

Therefore, in the face of economic crimes, it was you who were unlucky in the past and would investigate you. For other massive data, there is simply not so much energy to look it up.

Obviously, this is not a fish that slips through the net, but only a few unlucky fish can be caught once in a while.

Of course, the CCB also knows the severity, and here it is nothing more than a bet. They also didn't come up with data that was very sensitive and could contain evidence of a crime. What they get is "harmless" data that has been excluded.

Anyway, isn't your brother very good at bragging? There are so many financial experts in our CCB, and almost all of them are top students majoring in finance from prestigious universities. We all think it's harmless, can you see a ghost in that broken system in the mainland?

The corners of the female inspector's mouth were slightly hooked. She was proud in her heart, and whether it was fruitful or not, she could humiliate that soul in the end.

If you don't find an anomaly - you can't even find abnormal data, what's the use of your broken system? You Bei Lao is just unreliable!

If you find an anomaly - we CCBs have thought it is harmless, but your broken system finds an anomaly? No one wants to throw a trash can like this thing, right? What else can you Bei Lao have besides a hard mouth? Did you grow up eating poop?

Therefore, the honor of the Hong Kong police still depends on the old lady!

……

In the face of the suspicion and hostile gaze below, Li Yuan was confident on the surface, but he was still a little apprehensive in his heart.

After all, if there is no result, although it is completely possible to play a scoundrel, if you can not play it, it is better than tearing your face and being a vicious dog.

In his previous life, Li Yuan still knew some about big data detection of economic cases.

Because in a few decades, fraud, money laundering and other economic forms have actually been almost equivalent to telecom fraud, and basically have to use network tools.

When I was in a large factory, Li Yuan and several other technical directors also discussed this problem and proposed some solutions. So, you may not be familiar with it, but at least you know some of the principles.

Therefore, in the selection of function formulas and parameters, Li Yuan is not a loss. After a few operations, the system was up and running in no time......

Regarding Li Yuan's operation, Liu Pei still has the curiosity of a technical nerd. So he kept asking for advice, and Li Yuan also didn't hide his secrets, explaining some of the principles inside.

In fact, in the process of telecom fraud, the police and criminals are fighting wits and courage on the Internet. The two sides continue to come up with more advanced technology, and strive to achieve winner-take-all.

But in terms of principle, your telecom fraud will always leave traces of the flow of funds, involving money laundering tools, right? Therefore, it is necessary to find some kind of pattern in the massive data.

Truth be told, this already comes into the realm of psychology. What are you criminals used to doing? Let's find patterns from this. Criminals are constantly changing their behavior. The two sides are fighting wits and courage!

It can be seen that although Li Yuan only knows a little bit, it is already a mature experience summed up after countless battles of wits and courage.

In the end, the pig system finally calculated the result, and the abnormal data ...... Hey?

(⊙?⊙) (⊙?⊙)……

How many thousand pieces of anomalous data are there? Is this a den of thieves? Completely impossible, huh?

Li Yuan was wiped out all of a sudden. Could it be that there is really a major error in the hedgehog system? If such a result is handed over to that madam, it is almost certain that he will die on the spot!

If you don't make such trouble, can you find thousands at once? Anyway, Hong Kong Stone International Financial Center, are all the accountants here eating dry food?

mmp！ It was really cool to scold people just now, and now it's time to play big rules.

Seeing Li Yuan's eyes flickering, the female inspector sitting opposite couldn't help but laugh: "Hehe, Brother Yuan, is there a result?" Can you show us? ”

"What's the hurry?" Li Yuan's brain teaser turned, "The one just now was the primary election, and it will be selected later." ”

While talking, Li Yuan quickly operated. He immediately replaced the new function formulas and parameters, and chose a different approach.

The female inspector was already overjoyed: "What kind of questions, you can choose slowly!" Brother Yuan, we will accompany you today. If you're hungry, we'll order you pork chop rice. Hahaha......"

There was laughter from below. Seeing that Li Yuan was about to be embarrassed, those Hong Kong policemen were very happy.

Brother Yuan, what are you doing today?

"Hmph, I can use your pork chop rice? As long as you are quiet, don't act like a ghost. ”

"Okay! Brother Yuan doesn't look down on the food in our police station. Would you like to order takeout? Eat some abalone and lobster to rinse your mouth? I know you cheated thousands of dollars in remuneration. Hahaha......"

There was even more laughter below......

……

Li Yuan didn't know that in this era, those seemingly clever money laundering methods, in a few decades, would be almost a game for kindergarten friends. Which online financial regulator can't find out?

In a way, he has used the method of upgrading for decades, I don't know how many times, and he still pioneered the use of big data, that is, he is bullying people, which is simply a dimensionality reduction attack!

These anomalies are indeed anomalies. It's nothing more than primitive excesses, and the system was brute-forced.

It needs to be explained here: in the abnormal flow of funds, most of them are not black money, but gray money that is played on the sidelines. This amount is quite staggering, involving almost the vast majority of ordinary people. Intentionally or unintentionally paying a little less tax, it should be commonplace, right?

And yet suddenly there was such a brute force crack?

This is very similar to the DNA detection has just appeared, and the sudden dimensionality reduction blow has suddenly become like a dumpling.

Because of this, there are thousands of such exaggerated figures. Even Li Yuan himself couldn't believe it!

Regarding these gray money, even CCB will open its eyes and close its eyes, because manual deletion is really too busy. Breaking eucalyptus also needs to consider the cost. However, taking advantage of the computer's powerful computing power is nothing more than a matter of minutes.

Since it is a brute force attack, it will not take too long. After a different approach, the results were also quickly obtained.

Li Yuan's eyes were dark again - there were more than a thousand!

There's nothing to say, let's do it another way. This time, the conditions are even more demanding. Let's take a look at the picks.

After a while...... More than 700!

mmp！ Lao Tzu didn't believe it. Pick out the best of the picks...... More than five hundred?

It has already become a vegetable market at the bottom. Those Hong Kong police officers are waiting to set off firecrackers to celebrate.

"Brother Yuan, aren't you okay? Pork chop rice is going to be cold, huh? ”

"I think I'm already rancid, huh?"

"Hahahaha......"

has changed five or six methods, and Li Yuan is really powerless. In a hurry, he suddenly had an idea, and picked out all the results he had obtained before, those overlapping data.

And finally...... Article 156? Ahem. It should be barely possible...... Right?

Connect the printer and start printing the results.

The female inspector asked with a smile: "Brother Yuan, will I give you a chance one last time, can you say yes?" We can pretend that this thing didn't happen. Don't say that we Hong Kong police bully you mainlanders. ”

"Hmph." Li Yuan squinted his eyes, "Madam, it's so tiring to talk to you." To be honest, after staying with you for a long time, I have a sense of intellectual superiority. ”

"Okay!" The female inspector was, "When death is coming, you still have to be hard-mouthed." Let's open our eyes and see what system you have. Ha? More than 100? I can't help but give a thumbs up, you guys simply changed the name to the detective system, right? Hahaha......"

The bottom immediately burst into laughter. Even if there are only more than 100 left, it is also quite exaggerated.

You know, that's more than 100 clues, and even if you choose one of the two, there are dozens of cases. If it involves a wide range of people, it is hundreds or thousands of criminal suspects.

In just a few minutes, a broken system was inexplicably used, is it broken? So what do you need the police to do?

Those Hong Kong police officers are giggling and talking to each other. They waited for the female inspector to say her final judgment, and then went all out to Li Yuan......

Ready! Trolls Level 1 Combat Readiness!

Liu Pei on the side also noticed that the situation was not good, his face was full of worry, and he asked in a low voice: "Xiao Li, are you really sure?" ”

"Hey, what if you're not sure? Anyway, we won't admit it. ”

"Huh?" Liu Pei was taken aback, "Xiao Li, what should I do then?" ”

"Don't worry! They won't do anything to us. Anyway, the benefits that should have been obtained have already been obtained, who cares what they think? ”

"Huh?"

Liu Pei thought about it, and this was also true. From the point of view of donation, the purpose of all parties has indeed been achieved. As for what these Hong Kong police officers think? Is there so much to manage? They don't have much to decide.

"Then what about them looking for trouble later?" Liu Pei continued to ask.

"Of course scold back! Then let's run quickly. ”

"Hurry up?"

"Nonsense, don't run faster, what if someone doesn't want to do it? Heroes don't suffer immediate losses. ”

"Huh?" Liu Pei sweated at a waterfall. It turns out that you also know that heroes don't suffer immediate losses?

“……”

……

While everyone was waiting, an unexpected scene happened. The female inspector looked at the results, and her face was full of ridicule at first, but when she looked at it, she became frowning and thinking......

She watched it several times, hesitated again and again, and finally couldn't help but say to Li Yuan: "Brother Yuan, please ask, why did you make such a judgment here?" ”

Hearing the female inspector's weak tone, the Hong Kong policemen were shocked.

Li Yuan was also stunned, but he reacted immediately, and suddenly became smart: "Alas! If you don't listen carefully, the teacher is also very helpless! Scumbag? Hum. ”

Facing the murderous gaze of the female inspector, Li Yuan came to her side and began to explain the principle.

And those Hong Kong police officers are slowly surrounding, and they feel unbelievable, but they don't want this to be true - it can't be like this, right? Could it be that Brother Yuan is pretending to succeed again? Does that broken system really work?

After listening to Li Yuan's explanation, the female inspector fell into contemplation again. And Li Yuan also found a problem, how can there be a familiar name among these results?

The scene was quiet for a while, and the female inspector suddenly looked up and found that she was already crowded with people, she immediately looked solemn and scolded: "What are you doing here?" Dinner party, huh? All spread out, it's confidential! ”

Then she beckoned again: "Sir Yang, you stay for a while, here are the clues of your O's memory." ”

"Huh?"

Seeing the shocked faces around him, Li Yuan was secretly amused. I didn't expect that the economic situation here could still be related to organized crime? But it's not surprising that the stolen money always needs to be laundered.

Seeing that the female inspector and the Yang sir were about to leave, someone finally couldn't help but ask, "Madam, then ...... now?" ”

The female inspector felt a nameless fire: "You still want to keep it for pork chop rice?" Of course, get home! ”

“yes，madam！” The rest of the police dispersed. The female tyrannosaurus was angry, and no one could afford to provoke it.

The female inspector glanced at Li Yuan again, her expression struggling and hesitating.

Li Yuan deliberately pretended to be a villain: "Madam, if you want to say I'm sorry, then hurry up!" Now you know the quality of your Hong Kong police, right? Hahaha——! ”

The female inspector almost didn't tilt her nose: "Then thank you!" Brother Yuan! ”

"You're welcome! Wha——! ”

“……”
