Police Detective

Really lost!

Professor Tang is well-informed, but he is also a little dizzy at this time.

"Professor Tang, look at this file, what is it?" Wang Liang pointed out a path.

Professor Tang just glanced at it and said, "The experimental data during this period was encrypted. Is this the file that was lost?"

"Yes, that's it. This file has traces of being copied as a whole." Wang Liang said.

"Sure enough." Professor Tang held the table and nodded lightly.

"What encryption method is used?" Wang Liang looked at the folder and did not move it rashly.

"It's a professional software. This is it. Take a look." Professor Tang has discovered that Wang Liang is a professional and is very cooperative with Wang Liang.

"This? I've never seen it." Wang Liang frowned: "I can't open your file, and according to what you said, I opened this folder, and the files in it are probably destroyed. However, I opened Just because it doesn't open doesn't mean that others can't open it. There are many masters who are ten thousand times more powerful than me. Once the entire folder has been copied, it's useless no matter how tight the lock is."

"I understand what you said." Professor Tang said he understood: "That's why I'm anxious."

"Why don't you use Linux on your computer?"

"All the computers in the laboratory are not connected to the Internet and are physically isolated, so the system is relatively easy to use."

"That's right, this method of theft is useless no matter what system you use." Wang Liang asked: "So, how many people know the lock screen password of this computer? I have found no traces of intrusion. They should have entered directly after knowing the password. "

"My five students." Professor Tang introduced them one by one. The five students all have doctoral or postdoctoral degrees, and each of them has been with Professor Tang for at least three years.

There are five students, two male doctors, one female doctor, and the remaining ones include a male postdoctoral fellow and Ding Jianguo.

The computers in this laboratory are used to preliminary store data after each experiment, and students can also use it. Professor Tang will put the truly valuable data in an encryption software, and only he knows the password.

Bai Song listened carefully to Professor Tang's information about the five people and said: "If these five people have been following you, then one of them must have told his friends the password here. Oh no, he should call his accomplices and come in. Stolen."

"The truth is this. The problem is, if it is related to my students, there is actually no need to steal the data." Professor Tang was puzzled: "Most of the students also know these experimental data, although every Everyone only knows part of it, but it’s not as secretive as you think. We discuss it every day.”

"But these data rely on brain memory and cannot be remembered, right?" Bai Song asked rhetorically.

"Yes." Professor Tang glanced at the computer: "I can't write it all down."

The experimental data is not just a result, but also includes the details of the entire reaction change from beginning to end. It is completely impossible to memorize them all.

"That's it. This shows that there is still value in stealing." Bai Song asked: "I am not targeting anyone. Among your five students, are there any who think highly of themselves and have very average family conditions?

"There is no one who is particularly poor, and I still pay them wages." Professor Tang shook his head: "There is no one who has a high self-esteem. I have inspected all of these people, and I would not want them in the situation you mentioned. "

"It's so evil." Bai Song scratched his head: "You want to say that the data was lost by himself?"

"Let me check the video of the exit of the laboratory first." Wang Liang said: "Although there are no surveillance cameras in the laboratory, there are quite a lot of surveillance cameras in this building."

"There are blind spots in the surveillance in this building," Professor Tang said: "There are many cameras and they are relatively old, and they break down all the time, and they are often repaired. Although I don't care much about surveillance, if someone really comes here with a purpose. Stealing, you won’t be able to prevent this.”

"Wait a minute, let me ask again, are any of your students in need of a lot of money recently? Or have you just talked to someone?" Bai Song asked unwillingly. He always felt that this matter, from any angle, was for the sake of Money is the most basic motive for committing crimes.

"The only person I'm talking to is Ding Jianguo. I don't know how she is with that friend of yours, so I don't care."

"Well, that can't possibly require money." Bai Song shook his head.

The scientific researcher is really miserable. The five of them are at least 26 or 7 years old, and they are all single. Bai Song doesn't know if Ding Jianguo is single now. Wang Huadong is still slow to start.

"Even if it may have an impact, call all five of your students over." Several people tried several methods. Wang Liang went to check the surveillance system, and Liu Shuyuan began to investigate the scene.

Site inspection is also a basic skill. There is nothing to inspect in this laboratory, because there are shoe covers and the like when entering and exiting, but you still need to take a careful look.

"Why did you ask my students to come here?" Professor Tang and Bai Song asked alone.

"Chat." Bai Song said, "Let them hand over their mobile phones to me, and then you guys can continue chatting about this topic."

"I'm not in the mood to talk about this now." Professor Tang shook his head.

"You are not in the mood to chat. If someone steals it, you will definitely not be in the mood to chat." Bai Song said with a smile.

Professor Tang glanced at Bai Song and took a deep breath. Although he didn't want to doubt his students, he knew that this was the best way.

After finding a monitored classroom, Professor Tang called all the students over, began to discuss yesterday's experimental results, and continued to arrange tomorrow's experiments.

What is different from usual is that Professor Tang is very satisfied with the recent experimental results, and talks a little excitedly about the huge impact that these experimental results may have. Looking at this situation, Tang will be nominated for the Nobel Prize in Physics in a few years. .

Bai Song saw very clearly in the surveillance camera that there was something obviously wrong with one boy's expression. His surprise was not coming from the inside out at all.

After watching for more than ten minutes, Bai Song sent Professor Tang a WeChat message, indicating that he could make some sarcastic remarks.

Professor Tang was chatting exaggeratedly, but then he changed the topic and became serious again.

It must be verified through continuous experiments, otherwise it cannot be proved to be effective.

At this time, the male doctor's condition recovered a little.

Several students were confused as they listened to some of the things here. They had not yet fully understood some of the things here. When they heard the instructor bragging about B earlier, they all felt that 666, for this seemingly simple project, everyone here wrote (shui) There was no problem with publishing three or five papers, so why did the style of writing change again?

That was Ding Jianguo, who was a little thoughtful, but didn't say anything.
