"Bang Bang Bang"

At the same time, there was a knock at the door.

"Hey, the materials found in the Mahayana headquarters have basically been sorted out. It's been a rough ride. ”

"Did you find anything out of the ordinary?"

"Not found for the time being. Let's focus our search for the second time. ”

Jing Daosheng thought for a while and said: "Now we have two main doubts, the first is the shooting case in the square, and the second is the disappearance of Ning Feiyang. Let's start with the square case investigation. ”

In many detective-themed artworks, the audience can always see the attentive and careful image of the technical investigators, who can always accurately capture the clues left by the cunning criminal suspect through the "fog".

However, in reality, the technical investigation work seems to be a bit boring, because it is necessary to repeatedly reason and analyze a large amount of evidence and data to ensure the integrity and strength of the evidence, and give the relevant investigation departments the greatest help in solving the case.

Now the link that Jing Daosheng and Shu Hongzhen are doing is the data screening link, which is the most boring link and the most basic link. Without this link, there will be no subsequent reasoning and progress.

In this era, artificial intelligence has been quite perfect, and it is no longer like the "artificial intelligence" of thirty years ago that does not know anything, and can only play chess with humans to do some simple and repetitive work.

Twenty or thirty years ago, intelligent chat programs and human chats were like, "I don't seem to understand what you mean." "Say that again, please?" "Maybe you can change the question." Such an idiot answers. It can allow the user to move away from pleasure and reason in an instant, and towards pain and anger.

And the "Turing test"1, which was proposed a hundred years ago, was far from being able to reach the boundaries at the time. However, with the development of high-tech R&D clusters led by Xinhai City, artificial intelligence has moved to a new height. Wider and deeper coverage in various industries. The Turing test in the form of chat is also basically up to standard.

In this era where everything is data, huge amounts of data are naturally inseparable from machine computing and processing, and the data retrieved by the Mahayana company this time is 10 million terabytes, filling 100 military-grade storage boxes.

The decompression is ten times larger than the read state, and if you let humans review and screen, you can't find a hundred people to see these massive amounts of data in a lifetime.

Therefore, such a large amount of data is naturally inseparable from the help of powerful artificial intelligence retrieval, so that operators can quickly find the nodes they want to see.

"Let's focus on the three days before and after the shooting, I will screen the records in the square, and you will screen the records of the Mahayana headquarters building." Jing Daosheng gave instructions.

"Understood."

Before they knew it, it was close to noon, and the two of them had been facing the massive amount of data all morning without saying a word.

Suddenly, Shu Hongzhen broke the silence, raised his head and said excitedly: "I found a suspicious place!" ”

Jing Daosheng quickly leaned over and asked, "Where?" ”

"If you look at this record, the day of the shooting was June 3rd, and the Mahayana company secretly replaced part of the curtain wall in the early morning of the next day." Shu Hongzhen pointed to the screen and said.

Jing Daosheng was a little puzzled and asked, "What do you mean by secretly changing?" ”

"All Mahayana have also replaced the curtain wall of the building before, but this time the replacement record is different, and there is no clear replacement record."

"And how did you know they had replaced part of the curtain wall?"

"Look here, a record of the transportation and dispatch of large items, and here, the removal of large items from the backup warehouse, these two records are obviously together. Accompanying the transport convoy was a team of aerial workers. Although the details of the transported objects and the work at height are also not specified, I deduce that it is very likely that they replaced part of the curtain wall of the building. Shu Hongzhen skillfully switched and displayed various key information.

"As a large professional enterprise, the information recorded by Mahayana is pitiful and can be said to be extremely perfunctory, but this is an important work involving the repair of the building, and the paper records are so vague that there is obviously a problem and something to cover." Shu Hongzhen said reasonably.

"There is no logical problem with the above, but I have a question about what this curtain wall repair has to do with the shooting." Jing Daosheng asked suspiciously.

"Guy, you recall, the details of the square shooting, the ballistic analysis was shot from the Mahayana Building, but the side of the Mahayana Building facing the square is closed, from this point of analysis, drone shooting is more likely than fixed platform shooting, but from the current UAV stealth technology and high-energy weapon carrying technology, it is impossible." Shu Hongzhen slowly recounted the details of the shooting in the square, helping Jing Daosheng recall.

Jing Daosheng's eyes lit up when he heard this, "You mean, it is very likely that the Mahayana company will realize the design by destroying the curtain wall of the building, and then when the scene is blocked late at night, it will secretly replace the destroyed curtain wall to achieve 'perfect crime'?" ”

"Yes, that's what I think." Shu Hongzhen agreed.

"I still haven't thought of how to achieve it, you tell me. These cases have really drained my imagination lately. Jing Daosheng asked shamelessly.

"That's right, let me ask you, is the shooting an infrared laser?"

"Yes."

"Does infrared laser belong to light?"

"Of course."

"Does the exterior wall of the Mahayana building reflect light?"

Of course, Jing Daosheng knew the technical principle ......of the exterior wall of the Mahayana Building, but the glass exterior wall reflected high-energy lasers, which really made him a little unbelievable.

Jing Daosheng questioned the emission source: "Even if this is the case, where is the laser fired from?" ”

"Why, did you forget? The Mahayana building also has a fill-light emitter. to compensate for the lack of pure reflection of sunlight. ”

It's really possible to be said by Shu Hongzhen!

"What other basis do you have?" After all, there is only one circumstantial evidence for the maintenance of the exterior wall, and the maintenance of the exterior wall does not directly prove that the Mahayana company used the firing technology of the exterior wall to shoot police officers.

"No...... I can only find out these from the internal information, and the other records are not abnormal. ”

Jing Daosheng was not discouraged, and followed this line of thought and continued to check the data on his side.

After a while, Jing Daosheng raised his head and said, "I'll find one!" ”

After hearing this, Shu Hongzhen raised his head and waited for the explanation.

"Hongzhen, you see, this is the result of ballistic analysis. This is a video of the exterior wall of the Mahayana Building after the shooting. See something strange? ”

Shu Hongzhen carefully looked at the two demos on the screen and was surprised!

It turned out that after the shooting, there was no damage to the curtain wall of the Mahayana Building, and strange advertisements were still played as usual.

However, when the real-time recorded footage and the ballistic analysis of the gunshot overlapped, the problem became apparent: the small area of the shooting point (reflection point) was always completely black, but because of the clever design of the advertisement, the viewer automatically ignored the completely black area.

"This is definitely the evidence that the Mahayana company committed the shooting!" Shu Hongzhen was very excited.

In the past week, all the criminal cases have pointed to this leading enterprise in Xinhai City, but the two have not been able to catch the evidence. But now the integration of these several pieces of evidence is enough to show that the Mahayana company is the real culprit of the shooting!

But Jing Daosheng, as before, was not carried away by the sudden victory, quickly calmed down, and said to Shu Hongzhen: "Hongzhen, I am not going to immediately accuse the Mahayana Company. ”

"Why? The impact of the shooting is significant, and once we can prove that the Mahayana Company is the real culprit in this case, the Mahayana Company will definitely be doomed. ”

"You still take it for granted, just this one thing, Mahayana Company is as easy as a finger to deal with."

"How to cope? Shooting government law enforcement officers in full view. Shu Hongzhen asked puzzled.

"Suppose I'm a Mahayana company and I claim it's an accident caused by a technical glitch?" Jing Daosheng explained calmly.

"This ...... How is this possible? What about fools? Shu Hongzhen was still not convinced.

"You forgot what you said yesterday?"

"In this era of the city, this kind of magic is happening one after another, and I am gradually able to accept it." Shu Hongzhen's memory is not bad, and what he said yesterday was repeated as it was, but his tone was extremely lost.

Jing Daosheng comforted: "Hongzhen, don't be discouraged, this time it's not without gain, it's just that we choose to stay put, and when the evidence of other Mahayana companies is discovered by us, we will give him a punch." ”

"What's the matter, so what are we going to do next?"

"What's next? The next step is to eat first. Half an hour has passed. During the war, grain and grass go first, and we are the two of us who are in a hurry, and we can't go hungry. ”

Faced with the sudden humor of the matter, Shu Hongzhen laughed, "Yes, I haven't paid attention to the meal, let's walk downstairs in the canteen, the food in the canteen is special." ”

The two strode out of the office and got on the elevator to the cafeteria.

===============================================================

*The Turing test, invented by Alan Matheson Turing, refers to the fact that the test subject is separated from the test subject (a person and a machine) and asks random questions to the test subject through some device (such as a keyboard).

After multiple tests, if more than 30% of the test subjects cannot determine whether the test subject is a human or a machine, then the machine passes the test and is considered to have human intelligence.

The Turing test is a difficult hurdle that the computer field has been trying to overcome, and the term Turing test comes from a paper written in 1950 by Alain Matheson Turing, a pioneer of computer science and cryptography, "Computing Machines and Intelligence", 30% of which is Turing's prediction of machine thinking ability in the year 2000, and we are far behind this prediction.
