Chapter 217 The computer is not working
It is said that there are enough funds for economic investigation, but the prerequisite is to solve the case. If the case cannot be solved, where can we get the funds?
Dong-dong-dong.
"Please come in."
"Team Wang, there is news about Sun Yuting's case last year."
The person who knocked on the door was Sun Xiaotao, Wang Haiyi's right-hand man. He was proficient in finance and computers and was a rare compound talent.
In the past two years, there have been an increasing number of economic crimes involving the online transfer of stolen money.
But the previous professionals were either only proficient in finance or only proficient in computers.
When investigating similar cases, it was obvious that there was a shortage of manpower and insufficient capabilities.
“Oh?”
Sun Xiaotao's news cheered up Wang Haiyi: "What news?"
"It's news from the Haizhou Economic Investigation Detachment, saying that Sun Yuting was suspected of fraud and was arrested."
"Sun Yuting is suspected of fraud?"
Wang Haiyi was slightly startled: "Wasn't she defrauded?"
Sun Xiaotao smiled bitterly: "It was because of being defrauded that she owed a lot of foreign debt. I went to commit fraud, and the amount was quite large. The news over there said it was over 10 million.”
Ten million...
I was defrauded of 30 million, but I turned around and defrauded others of 10 million.
This...it's hard not to call him a talent.
When Wang Hai received the news, Lu Chuan also called Captain Qin Hui of the QZ City Criminal Investigation Detachment to ask about the situation.
I mainly want to see the files on Sun Yuting’s case.
Of course Qin Hui would not refuse such a trivial matter.
In less than half an hour, the relevant files were sent to Lu Chuan through the intranet.
The person who defrauded Sun Yuting didn't think the whole method of committing the crime was very clever.
Sun Yuting learned it easily.
However, compared with Sun Yuting first, the other party was more cautious. During the interaction with Sun Yuting, he basically left no useful information.
There are quite a few photos, but most of them were taken in groups, with low definition and relatively blurry ones.
There are no single photos, but there are some photos with Sun Yuting, but they are all from behind.
In other words, he will always be Sun Yuting's backer.
So, the QZ City Economic Investigation Detachment has never found the other party through face comparison.
As for fingerprints...
The face is blurry, let alone fingerprints.
The methods used to solve crimes through economic investigation are different from those used during criminal investigation.
Most of the criminal suspects wish there was no trace of themselves at the scene.
Thinking of every possible way is like trying to hide one's identity.
But fraud cases are different. Except for face-to-face telecommunications fraud, the actual identity of the fraudster who uses himself as a bait is real.
But most of them use fake identities.
This is true for Sun Yuting, and so is the person who defrauded Sun Yuting.
Therefore, the way of finding people through criminal investigation is different from that of criminal investigation.
They rarely use fingerprints, footprints and other technical means to determine the identity of the other party.
The last time I asked Lu Chuan to help extract the fingerprints on the envelope, it was actually not to find someone, but to fix evidence of the suspect's bribery.
"The identity of the suspect who defrauded Sun Yuting has not yet been determined, and the progress of the case there is not going well."
The Haizhou City Economic Investigation Detachment also learned about the other party's case.
Li Song called Lu Chuan personally.
"Brother Li, if the suspect's photo is clearer, is it possible to find him?"
"It is indeed possible. Our economic investigation side works closely with customs, airports, and train stations. "These places have facial recognition systems, especially customs and airports, and the accuracy of facial recognition is very high."
“If you can get a relatively standard headshot photo of the other party, you can compare the other party’s true identity.”
This is the method commonly used by the Economic Investigation Detachment to find people.
However, most of the time, the suspect's facial features are not easy to extract.
For example, the photos left by the suspects in the Sun Yuting fraud case were either from the back, or were unclear group photos taken with a mobile phone.
This kind of photo simply does not meet the standard photos that mark facial features for comparison.
The QZ City Economic Investigation Detachment also asked people from the Picture Investigation Brigade under the Criminal Investigation Detachment to process these photos and even reported them to the provincial department.
After all, the amount of money involved in the case is huge, so it is possible to ask for the support of picture investigation experts from the Provincial Technical Appraisal Center.
Just one year has passed, and there is still no news from there.
It is not that the processing is not successful, but that it needs to be queued.
The 30 million case is a huge fraud case in QZ City, but in the whole province, it may not be considered a particularly big case.
The provincial department's establishment is notoriously small, and experts in picture investigation simply do not have the time and energy to handle all the following technical support.
Picture processing is different from ordinary work and takes a lot of time.
Especially for portraits, this type of more complex image processing is even more time-consuming.
Lu Chuan often takes an hour or two to process fingerprints, even if they are not too complex. Fingerprints are just line images, which can be regarded as the simplest type of image processing.
From this, it can be imagined that the processing of face images is much more complicated.
What's more, whether it is the provincial department or the municipal bureau's picture investigation team below, the actual people doing the work are real people.
A portrait does not represent a case in their eyes, just a piece of work.
Lu Chuan hung up the phone and looked carefully at the hero of Sun Yuting's deception case.
If you look at it with the naked eye, you can definitely recognize this person at a glance.
However, the requirements for system comparison are much higher.
Looking at it now, Lu Yao’s more than ten million can be recovered at most five million.
To recover the rest, the best possibility is to catch the suspect who deceived Sun Yuting.
Then I also pray that the other party will not lose all 30 million within a year.
Of course, spending 30 million a year... is unlikely.
Opening the image processing software, Lu Chuan tried to manipulate it.
Lu Chuan wanted to use the image processing technology in the advanced fingerprint identification analysis skills to process the man's head in the group photo.
“Ding!”
“Advanced mission: Help Lu Yao recover the 10 million that was defrauded, gain the other party’s gratitude, and save Lu Yao’s childhood that is about to be lost.”
Has the system learned to joke?
Why is Lu Yao's new year's money related to his childhood?
Who didn’t kowtow too much for pocket money when they were young?
Of course, 99% of people cannot be like Lu Yao and have 10 million New Year's money.
The processing of portraits is very different from what Lu Chuan imagined.
Fingerprint image processing is basically line segment processing, and data analysis can be performed using simple or complex digital image transformations.
But the portraits are different.
The digital image changes of portraits are obviously much more complicated than fingerprints.
Especially when it comes to light and dark changes in light, it is very difficult to deal with.
Lu Chuan's computer is not a dedicated image processing computer, and the processing speed is very slow.
An hour passed and the computer crashed five times!
However, there is basically no progress in the processing of target portraits.
"This won't work."
