Shenhao started after the college entrance examination

When Kishijima Maple reported before, Anliang felt that something was wrong. According to the rigor of a mathematician's crime, why would such a flaw be left?

Now after analyzing the Tianji system, the problem has indeed been discovered.

According to the analysis of the problems discovered by the Tianji system, the mathematicians must have checked the locations in advance before the crime occurred, so as to make careful plans based on the situation at the crime location.

In addition, after the crime occurred, the mathematician returned to the crime scene again. As for what the mathematician did when he returned to the crime scene, An Liang is not clear yet.

Although mathematicians tried to get away with it by cleaning up the video recordings from the security surveillance system and carefully editing and splicing them together, there were always holes.

Since there is a flaw, we can continue to investigate around this flaw.

Mathematicians tampered with the security monitoring system at the crime site. Have the security monitoring systems around the crime site been processed by mathematicians?

Regardless of whether the security surveillance system around the crime scene has been processed or not, more flaws will be revealed.

If the security monitoring systems around the crime scene have still been processed by mathematicians, then continue to expand the scope of the investigation. Mathematicians cannot deal with more security monitoring systems endlessly.

After all, there is a risk of exposure when dealing with security monitoring systems, such as being recorded by a private security monitoring system, or being discovered by passers-by, or even being discovered by the security monitoring system manager.

It would be simpler if the surrounding security monitoring systems were not processed by mathematicians. Through the Tianji system, the information recorded by the surrounding security monitoring systems can be quickly analyzed and cross-compared with the crime scene.

Through cross comparison, it is possible to find out the persons who are recorded in the security monitoring system around the crime scene but not recorded in the security monitoring system at the crime scene.

The cross-comparison results are then further analyzed to exclude routine local personnel, thereby screening out irregular personnel.

Based on this result, by further screening the information of entry and exit personnel, it is possible to lock in highly suspect targets.

Once a highly suspect target is identified, a more in-depth investigation can be conducted.

In this age of big data, what else can’t be found?

Unless you have left no trace at all in this big data world, you will definitely be discovered, and your life trajectory may even be reconstructed, etc.

"BOSS, there is also a problem with the security surveillance video record at the time of the incident!"No. 4 Tianji Divine Calculation Supplement

"Um? An Liang asked back,"Could it be that the security monitoring records at the time of the incident were also falsified?""

Logically speaking, it should be impossible!

Because if there are problems with the security surveillance video records at the time of the crime, both the Dongjing Metropolitan Police Department and the Neon Intelligence Investigation Bureau will intensify their investigation.

It is precisely because There was no problem with the security surveillance video record at the time of the incident, so the Tokyo Metropolitan Police Department and the Neon Intelligence Investigation Bureau did not conduct a more careful and wider investigation.

"Not fake."No. 4 Tianji Divine Calculator responded,"BOSS, I will send you the corresponding information. You read it while I explain it to you."

"OK"An Liang picked up the tablet and prepared to receive the information sent by the No. 4 Tianji Divine Calculator.

After a while, the No. 4 Tianji Divine Calculator sent two videos.

"BOSS, please check the first video first."Tianji Divine Calculator No. 4 reminded.

An Liang clicked on the first video. This video was of a little boy walking with a floating helium balloon, and then the helium balloon suddenly exploded.

Tianji Divine Calculator No. 4 explained. ,"Under normal circumstances, there is nothing wrong with this video. After all, the cameras of the public security surveillance system are not high-definition high-speed cameras and cannot capture clear details."

"So there is a problem!"An Liang answered.

"There is indeed a problem!"No. 4 Tianji Shensuan responded,"We use the Tianji system to analyze these security surveillance video records normally, and then let the Tianji system analyze these security surveillance video records at the pixel level."

"From a pixel level, although the cameras of public security surveillance systems are not high-definition high-speed cameras and cannot capture detailed information clearly, they can also capture some blurry things."Explanation of No. 4 Tianji Divine Calculation

"For example, if you use a mobile phone camera to take pictures of an aircraft engine or propeller, some strange phenomena will occur. In fact, this is caused by the fact that the mobile phone camera does not have high-speed photography capabilities, but the mobile phone camera still records part of the image information."No. 4 Tianji Divine Calculation Supplement

"Therefore, at the pixel level, the security camera at the crime scene captured the abnormal situation at the time of the crime!"Tianji Divine Calculator No. 4 warned,"BOSS, look at the second video."

An Liang clicked on the second video. This video was full of square pixel style. It was still the same as the explosion of the helium balloon during the previous incident, but before the balloon exploded, there were some changes in a few pixels in front of the balloon.

This change was specially marked. An Liang observed it several times before confirming that there was indeed a change in pixels.

"So what's going on?"An Liang asked.
