Assisted in cracking the 2.773 billion tax fraud case in Zhejiang, this computer professor is on fire

What would it be like when a computer professor solves a case?

Save 2.773 billion yuan for the country!

This case still involves a series of tax fraud cases on the scale of 54 companies across the country.

One of the Hidden Figures behind this is Professor Shen Wei from the Department of Computer Science, Zhejiang Sci-Tech University.

After this battle, his deeds quickly became popular on the Internet, and the People’s Daily “liked” it:

Some netizens also commented that “this is the correct way for intellectuals to open up.”

So what contribution did Professor Shen Wei make in the process of solving the case?

Provide key evidence to solve the case

Regarding this case, it still needs to be traced back to May 2018.

At that time, the tax department discovered that an import and export enterprise in Ningbo had received a large input invoice, the amount of which was as much as 29.75 million yuan.

The product name of this incoming invoice is the attitude stabilization controller, and its core is a chip.

The price is generally from tens of yuan to hundreds of yuan, and the slightly more expensive ones will reach thousands of yuan.

And the clue of the case is precisely in this – suspected of falsely opening tax fraud.

As the auditors stated:

If these attitude stabilization controller exports are real, they can be equipped with all civilian UAVs in the world.

As a result, the inspectors launched more in-depth investigations and visits, and as a result, a chain of tax fraud loomed.

But to prove this point, the inspection team of the Inspection Bureau also needs a key technical evidence to prove that these attitude stabilization controllers have the phenomenon of “low value and high report”.

Therefore, in September 2020, the case inspection team was introduced to Professor Shen Wei.

In the introduction of “Qianjiang Video”, Professor Shen Wei said:

For any chip, it has a corresponding datasheet (something), which we generally call a specification.

We judge whether this chip is consistent with its specification.

In order to find such critical evidence, Professor Shen Wei followed the inspection team to visit Shenzhen to obtain relevant product information.

After returning to Hangzhou, Professor Shen Wei and the engineers started to develop test tools.

However, the test results were quite shocking.

Professor Shen Wei found that it is impossible to program code on these chips:

Initially we suspected that an old chip was being used.

However, the chip doesn’t move at all. Or it’s just a model that doesn’t do anything.

In other words, the chips involved in the case are completely unable to achieve the functions of the software listed in the product manual.

In Shen Wei’s words, “this is a crazy scam”.

Professor Shen Wei provided rigorous key evidence from a technical point of view in this case.

It is understood that the case involved 54 enterprises across the country, and a total of 2.773 billion yuan was recovered for the country.

In view of Professor Shen Wei’s contribution in this case, he also received a letter of thanks from the First Inspection Bureau of Ningbo Taxation Bureau.

But Professor Shen Wei commented on himself very low-key:

To be honest, I don’t think I’ve done a great job.

Not the first time to help solve a crime

Professor Shen Wei graduated from the School of Computer Science and Technology, Zhejiang University, and is currently working in the School of Information, Zhejiang Sci-Tech University.

His research areas include intelligent control, cloud computing and artificial intelligence.

It is not the first time for Professor Shen Wei to assist in the investigation and solving the case.

It is understood that he had the experience of “cross-border solving cases” earlier.

For example, Professor Shen Wei has assisted Jinan Railway Public Security, Cangnan Public Security and other units to crack a number of bank card fraud cases.

In his view, every case is a cross-border fusion:

I keep telling my students that computing is everywhere. Our computer has become more and more a basic subject like mathematics.

All walks of life are inseparable from computers. Studying our computer major is still very promising.

Solving crimes with computer technology

In addition to the incident of Professor Shen Wei, there have also been incidents of teachers using algorithms to solve cases before.

For example, in 2019, the family of a tenured associate professor of computer science at the University of Notre Dame were robbed of a car by robbers.

With the help of two doctoral students, the Chinese associate professor launched an application on his mobile phone and used a greedy algorithm to successfully retrieve the lost car within 24 hours.

The speed can be called a “second kill” for the American police. At that time, the police at the scene sent out this emotion:

They shouldn’t have messed up with computer science professors!
