It's often said that economic investigation cases have ample funds, but the prerequisite is to solve the case. If you can't solve it, where do you find the funds?

Knock, knock, knock.

"Come in."

"Captain Wang, there's news about Sun Yuting's case from last year."

Entering was Sun Xiaotao, Wang Haiyi's trusted capable hand, an expert in both finance and computers, a rare multidisciplinary talent.

In the past two years, economic crimes involving online transfer of stolen funds have been increasing.

However, previous professionals either only excelled in finance or computers.

When handling similar cases, there was a noticeable shortage of manpower and insufficient capability.

"Oh?"

Sun Xiaotao's information invigorated Wang Haiyi: "What's the news?"

"It's from the Haizhou Economic Investigation Team. They said Sun Yuting is suspected of fraud and was arrested."

"Sun Yuting suspected of fraud?"

Wang Haiyi was slightly stunned: "Wasn't she the one being defrauded?"

Sun Xiaotao smiled bitterly: "It's because she was defrauded and owed a lot of debts that she turned to fraud herself, and the amount is not small. The news says it's over ten million."

Ten million...

She was defrauded of thirty million, then turned around and defrauded others of ten million.

This... it's hard not to call her a talent.

When Wang Haiyi received the news, Lu Chuan also called Captain Qin Hui of the Qinzhou Criminal Investigation Team to inquire about the situation.

The main aim was to look at the case files of Sun Yuting's case.

Qin Hui wouldn't refuse such a minor request.

In less than half an hour, the related case files were sent to Lu Chuan through the intranet.

The person who defrauded Sun Yuting did not employ particularly sophisticated methods.

Sun Yuting learned quite easily.

However, compared to Sun Yuting, the other party was more cautious, leaving hardly any useful information during the dealings with her.

There were quite a few photos, but most were group shots, not very clear, rather blurry.

There wasn't a single individual photo, and the few photos with Sun Yuting were all of back views.

As the culprit would say, he wanted to be Sun Yuting's forever support.

So, the Qinzhou Economic Investigation Team never managed to identify the person through facial recognition.

As for fingerprints...

The face is blurry, not to mention the fingerprints.

The approach for solving economic investigation cases differs from criminal investigation.

Most criminal suspects would prefer not to leave a trace of themselves at the scene.

Trying every way to hide their identity.

But fraud cases are different; except for telecommunication fraud where there's no face-to-face contact, fraudsters using themselves as bait have identities.

It's just that most of them use fake identities.

Sun Yuting is such, and so is the person who defrauded her.

Therefore, the method of finding people in economic investigations differs from criminal investigations.

They rarely use fingerprints, footprints, and other technical means to identify the suspect.

Last time when Lu Chuan was asked to extract fingerprints from the envelope, it wasn't to find someone, but to secure evidence of bribery.

"The identity of the suspect who defrauded Sun Yuting is still undetermined. The progress of the case over there isn't going too well."

Haizhou Economic Investigation Team also looked into the case over there.

Li Song personally called Lu Chuan.

"Brother Li, if the suspect's photos were clearer, would it be possible to find them?"

"There indeed is such a possibility. Our economic investigation team maintains close contact with units like customs, airports, and train stations."

"These places all have facial recognition systems, especially customs and airports, where the precision of facial recognition is very high."

"If a standard photo of the suspect's face can be obtained, it can be used to match the suspect's real identity."

This is a common method used by the economic investigation team to find people.

However, most of the time, the facial features of suspects are not easily extractable.

For example, the suspect in Sun Yuting's fraud case left photos that were either back views or unclear group photos taken with a phone.

Such photos simply do not meet the standard for facial feature matching.

The Qinzhou Economic Investigation Team also asked the Criminal Investigation Team's subordinate Image Investigation Team to process these photos, even reported to the provincial department.

After all, given the huge amount involved, it's possible to request support from the image investigation experts at the provincial department's technical appraisal center.

But a year has passed with no news from there.

It's not that processing was unsuccessful, but rather there's a queue.

A thirty million case is a huge fraud case in Qinzhou, but across the province, it may not even count as a major case.

And the provincial department is notoriously understaffed, with the image investigation experts having neither the time nor energy to handle all technical support from below.

Image processing is not like regular work; it's extremely time-consuming.

Especially with portraits, this kind of complex image processing is even more time-consuming.

Even when Lu Chuan processes fingerprints, though not too complex, it often takes one or two hours, and fingerprints, being line-type images, are considered the simplest type in image processing.

From this, one can imagine how much more complicated facial image processing is.

Moreover, whether it's the provincial department or the local city's Image Investigation Team, the ones doing the actual work are real people.

In their eyes, a portrait does not represent a case, but just a task.

Lu Chuan hung up the phone, carefully observing the male lead of Sun Yuting's fraud case.

By naked eye, it would be easy to recognize this person at a glance.

But system matching demands are much higher.

Currently, the most that can be recovered from Lu Yao's loss of over ten million is five million.

The biggest hope of recovering the rest lies in capturing the suspect who defrauded Sun Yuting.

And then hope that the suspect hasn't squandered the thirty million within a year.

Of course, spending thirty million in a year... is not very possible.

Lu Chuan opened the image processing software and tried to manipulate it a bit.

Lu Chuan wanted to use the advanced fingerprint identification and analysis skills related to image processing to handle the man's face in the group photo.

"Ding!"

"Advanced task: Help Lu Yao recover the defrauded ten million, earn his gratitude, and save Lu Yao's childhood from being lost."

Is the system learning to joke?

How did Lu Yao's new year money relate to childhood?

Who hasn't bumped heads for pocket money during childhood?

Of course, ninety-nine percent of people could never have ten million in new year money like Lu Yao.

Processing the portrait differed greatly from what Lu Chuan imagined.

Fingerprint image processing mostly involves line segment handling, using simple or complex mathematical transformations for data analysis.

But portraits are different.

The numerical transformations in portraits are clearly much more complex than fingerprints.

Especially when it involves changes in light and shadow, it becomes extremely challenging to handle.

Lu Chuan's computer isn't a specialized image processing computer, making the processing speed very slow.

After an hour, the computer crashed five times!

Yet there was almost no progress in processing the target portrait.

"This won't do."
