The monitoring of the laboratory is not available in all areas, and there are blind spots, so the only evidence that points to the suspect in the data theft incident in the laboratory is the record of the finger vein identification lock.

But this record shows that it is their own......

Professor Yao and his friends from the Security Bureau could not find evidence to prove their whereabouts during the time period of the incident, so with that record, they could basically prove that they had entered the laboratory at that time.

After all, finger veins are not faked like fingerprints......

However, he was sure that he had never entered the laboratory at that time, but he was the first suspect without evidence and without evidence.

In addition, later, the network protection system developed by the headquarters of the Japanese company that he signed a contract directly used the stolen system code, so he happened to sign the contract with the Japanese company himself before the incident......

He has become a suspect with a clear motive!

With such a clue, in the eyes of outsiders, he sold the research results of his mentor for the sake of work, and successfully entered the work of a large company......

Spy!

Calming down and straightening out his thoughts, Gao Yuan couldn't help but notice how unfavorable the whole thing was to himself-

The motive for committing the crime, in order to enter the company; At the time of the crime, no one could prove their whereabouts at the time of the crime; Evidence of the crime, records of entry and exit of the laboratory.

And the real situation in the end -

I got into that company, and the company's newly developed system used stolen algorithmic data......

In this case, once you call the police, how can you clear your suspicions?

And if the mastermind behind the scenes is related to the company, they can also point to the incident they committed, then they will be completely speechless at that time!

Thinking of this, Gao Yuan was very surprised, and looked at his mentor-

Unexpectedly, the teacher actually hid the whole thing directly......

And I was confused, I really worked in that company for almost four years, but it turned out that it wasn't for the reminder of my colleagues and the advice of Shiho Miyano, and I didn't even notice anything wrong......

So now, when you know what the situation is, what should you do?

The teacher's question was to ask me what I thought was the way it was to be in the situation.

I obviously didn't go to the laboratory that day, why did I leave a record of my access?

Thinking of this, subconsciously and uncontrollably, Gao Yuan looked up at Professor Yao and asked with some solemnity:

"That'...... Background data of finger vein recognition system......"

"The data cannot be changed in the background of the access control system of the finger vein lock."

Before Gao Yuan finished speaking, Professor Yao understood what Gao Yuan wanted to ask, and immediately gave an explanation.

In this regard, Gao Yuan's expression changed slightly, and looking at his mentor, as if he remembered something, he said tentatively:

"But...... Teacher, I remember that you emphasized on the first day of your lesson, that 'the essence of human society is a grass platform', no matter how large an organization or group is, its essence is composed of a structure full of loopholes and a large number of manpower, and because of this, even if someone designs the most sophisticated architecture or program, as long as it is still in human society, there will inevitably be loopholes that can be broken at the touch of a button, even if it may not be a problem with the program itself. Therefore, human beings will not completely leave their fate to the so-called procedures or processes to operate, and there will always be backdoors...... Therefore......"

In this way, Gao Yuan said this, in essence, he questioned Professor Yao's words just now, but at the same time, Gao Yuan was still very apprehensive in his heart when he said this passage itself, after all, this was equivalent to questioning his own teacher with his own teacher's words.

However, unexpectedly, hearing Gao Yuan actually say this, Professor Yao's face did not show anger, but showed a relieved smile, and nodded silently:

"Well, if you keep remembering this sentence, it means that I am not wrong. That's right, as long as it's a program written by a person, there is no absolute perfection, so the background data of the access control system can't be changed. It's just that...... I didn't leave a backdoor in the system.,If you want to change the data, you have to directly recompile the program itself.,And the authority is here.,From the appearance of the access control record that night to the time I found the record.,It's impossible for anyone to do this and not be discovered by me.,So this background record is credible.。 That's not the problem. ”

In this way, Professor Yao denied Gao Yuan's first conjecture.

After that, Gao Yuan thought about it again and said:

"Then there is only one other possibility, when someone entered the finger vein information, he wrote his finger vein information into my name!"

- Finger vein information is not a fingerprint, and it is almost impossible to fake it at present, so there must have been a verified person's finger vein that scanned the access control system, but in the end the record was shown to be his own name.

In this way, Gao Yuan said such an analysis.

In this regard, Professor Yao nodded slightly:

"A more reasonable idea."

"So...... In fact, as long as you verify whether the corresponding name displayed in the system matches each person after being identified by the finger vein of the access control, it is actually ......"

Hearing this, Gao Yuan found that if he thought about it like this, the whole thing had an investigative idea, so why......

"It's a pity that no anomalies were found."

Professor Yao couldn't help but say:

I found people who might have been suspicious at the time, and asked them to check each finger one by one through the finger vein recognition system, and compare it with the corresponding name in the background. But it was not found that the finger vein of a certain finger is displayed in the system as your name. ”

"What about Yun Xuezhe?"

Hearing this, Gao Yuan couldn't help but say anxiously:

"Judging from the current situation, the person who stole the data in the first place may be him!"

"It's too late to say that. After you graduated, the lab deleted your finger vein data, and didn't put students from other grades and tutors on the suspicion list, and now it's impossible to investigate. ”

Professor Yao said this, then looked at Gao Yuan, and said:

"Barely qualified, though...... So now, it's still a lot worse than the original truth. How, are you going back to work now that nothing has happened, or do you want to figure out what this is all about? ”

"I ......"

Hearing this, Gao Yuan couldn't help but lower his head, a little indignant:

"Now, how can I go back to work as if nothing had happened......

"It's a big deal to change jobs. In China, I can recommend it to you, but those jobs should not be as good as your current salary. ”

Professor Yao said indifferently.

"I ...... I want to investigate......"

In this regard, Gao Yuan, who had been thinking for a long time, finally said so.

Hearing this, Professor Yao was silent for a moment, and then said seriously:

"Are you sure? I can tell you that the complexity behind the whole thing is beyond your imagination, and what is hidden in it is supposed to be an extremely secretive international criminal organization, and so far, there are no clues about the organization of the police in various countries. If you continue to investigate, you may be in great danger. ”
