Stay away from Conan

Laboratory surveillance is not available in all areas, and there are blind spots. Therefore, the only evidence pointing to the suspect in the laboratory data theft incident is the record of the finger vein identification lock.

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

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

After all, finger veins can’t be faked like fingerprints…

However, I was convinced that I had never entered the laboratory at that time, and that I was the first suspect without any evidence.

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

He becomes a suspect with a clear motive!

With such clues, in the eyes of outsiders, I betrayed my mentor's research results just for work, and successfully entered a large company...

spy!

After calming down and straightening out his thoughts, Gao Yuan couldn't help but realize how detrimental the whole thing was to him——

The motive for committing the crime is to enter the company; the time of committing the crime, no one can prove his whereabouts at the time of the crime; the evidence for committing the crime is the entry and exit records of the laboratory.

And the final true situation——

I entered that company, and the newly developed system of that company used stolen algorithm data...

In this case, once the police are called, how should I clear my suspicion?

And if the mastermind behind the scenes is related to the company, they can also testify that they committed the incident, and then I will be completely unable to defend myself!

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

Unexpectedly, the teacher actually concealed the whole matter...

But I was confused. I had really worked in that company for almost four years. But it turned out that it wasn’t because of my colleagues’ reminders and Miyano Shiho’s suggestions that I didn’t even notice anything was wrong...

So now, after learning about the situation at that time, what should I do?

The teacher’s question was to ask what I thought was going on to cause that situation—

I obviously didn't go to the laboratory that day, so why was it me who left the entry and exit records?

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

"That... refers to the background data of the 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 response, Gao Yuan's expression changed slightly. He looked at his mentor, as if he was recalling something, and said tentatively:

"But...Teacher, I remember that you emphasized on the first day of class that 'human society is essentially a grassroots team.' No matter how large an organization or group is, its essence is a structure full of loopholes and a large number of It is composed of countless manpower, and because of this, even if someone designs the most sophisticated structure or program, as long as it is still in human society, there must be loopholes that can be broken at a touch, even if it may not be the program itself. problem. Therefore, human beings will not completely leave their destiny to the so-called programs or processes, and there will definitely be backdoors... Therefore..."

In this way, what Gao Yuan said was essentially questioning Professor Yao's words just now. But at the same time, Gao Yuan was still very uneasy after saying this. After all, it was equivalent to questioning his own teacher based on his own teacher's words. .

However, when he heard Gao Yuan actually say this, Professor Yao did not show any anger on his face. Instead, he showed a happy smile and nodded silently:

"Very good. You can always remember this sentence, which means that I did see the right person. Yes, as long as the program is written by people, there is no absolute perfection. Therefore, it is not absolute that the background data of the access control system cannot be changed. It's just that ...I did not leave a backdoor in the system. If I want to change the data, I have to recompile the program itself directly, and the authority is mine. From the time the access control record appeared that night until I discovered the record, it is impossible for anyone to do this without being discovered by me. So this background record is credible. That’s not the problem.”

Saying this, Professor Yao negated Gao Yuan's first conjecture.

After that, Gao Yuan started thinking again and said:

"Then there is only another possibility. When someone entered the finger vein information, he wrote his finger vein information as my name!"

——Finger vein information is not a fingerprint. It is almost impossible to forge it at present. Then someone who passed the verification must have scanned the access control system with his finger vein, but in the end the record showed his own name.

In this way, Gao Yuan made such an analysis.

In this regard, Professor Yao nodded slightly:

"A more reasonable idea."

"Then...actually, we only need to verify whether the corresponding names displayed in the system match each person's finger vein identification after passing the access control. In fact..."

Hearing this, Gao Yuan found that if he thought about it this way, the whole matter had an investigation idea, so why...

"It's a pity that no abnormality was found."

Professor Yao couldn't help but said:

I found people who might be suspects at the time, and asked them to check each finger through the finger vein recognition system one by one, and compare it with the corresponding name in the background. However, no one has found that the finger vein of a certain finger is displayed as your name in the system. "

"What about Yun Xuezhe?"

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

"Judging from the current situation, he might have been the one who stole the data in the first place!"

"It's too late to say this now. After you graduated, the laboratory deleted your finger vein data. Students from other grades and other tutors were not included in the suspect list at the beginning. Now it is impossible to investigate again. ”

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

"However, I'm barely qualified... So now, it's still a long way from the original truth. Now, are you going to go back to work in the company as if nothing happened, or do you want to find out what's going on? "

"I……"

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

"Now, how can I pretend that nothing happened and go back to work as if nothing happened..."

"The worst case scenario is to find another job. In China, I can recommend some to you, but those jobs shouldn't be comparable to your current salary."

Professor Yao said very calmly.

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

After thinking about this for a long time, Gao Yuan finally said this.

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. Hidden inside it should be an extremely secretive international criminal organization, and so far, the police in various countries have no knowledge of this organization. Get some clues. If you continue to investigate, you may face great dangers."
