Although landing on this planet was an accident, and my parents didn't think about how long they would stay here, as the core key to returning to Mingxing, and there were many thieves at that time, my parents still made certain protective measures for BT's safety.

As early as '03, when BT was placed here, my father donated a sum of money to the shopping street for the purchase of cameras.

In the past six years, he paid for the replacement of all cameras with high-definition cameras because of multiple damage and blurry images.

In addition to the property has the permission to call up and view, Yan'an also has a "back door" to view.

However, the security here is getting better and better, and the thieves also know that there are cameras all over the place, which can be called 360 degrees without dead ends, and over time they will not come here to "work".

Usually nothing happens, Yan An is too lazy to look at it, so he will be supervised by BT, and report to him if there is any special situation.

Obviously, this is the special case.

Yan An received four photos from BT, with this commercial street in the background.

The person in the photo was wearing ordinary clothes, and his eyes were bright, but he couldn't see anything unusual, so he sent it with BT's explanation.

"Your Excellency, Captain, it has been observed that these four people entered together before you arrived at the shopping street and then dispersed nearby, this behavior is not in line with the characteristics of group activities, and there is an anomaly.

After being dispersed in the vicinity, the four did not interact with anyone else, and looked at the surveillance camera several times.

According to the analysis of similar behavior data, their actions are more than 80% consistent with the thieves committed by the gang, and it is recommended to be vigilant. ”

Different people have different styles of behavior, when the behavior and actions are 60% similar, you can basically be sure that they are doing the same thing, and 80% similar only shows that the gang is not only stealing, but also very professional.

Why would you think of stealing in a place full of surveillance? Why didn't they leave when they found the camera?

Yan An couldn't figure it out, and there was no need to figure it out, so he dialed a phone call and went out.

It only rang and it was connected.

On the other end of the phone was Gao Shenghan, "Are you responsible for catching thieves?" ”

Straight to the point, Yan An asked such a sentence directly, which made Gao Shenghan a little unable to react.

"What? Where are you? Thieves nearby? Don't provoke him, I'll let someone take care of it. ”

After the thief is discovered, it is very likely to hurt people out of the psychology of jumping off the wall in a hurry.

Gao Shenghan didn't want Yan An to make a mistake, so he hurriedly warned him.

"I know, they haven't stolen yet, but they look alike.

I'll send you the photos and see if you can find someone to handle them. ”

After speaking, Yan An sent an MMS message over.

Gao Shenghan on the other end of the phone looked at the photo and was speechless.

I don't know how Yan An did it, the four comrades led by Wang Zhifang were all pulled out by him, and the angle of view of the photos should be taken by the camera, so they didn't notice it when they were photographed.

In this regard, Gao Shenghan wronged Wang Zhifang, can they not know how to avoid the camera, but this commercial street is well-known for its good security in the south.

There are hundreds of cameras on a street, and the closer they get to Yan An, the more cameras there are in the shops, and there are no dead ends at all, so how can they avoid them.

And just like the reason why Gao Shenghan was photographed by the camera at the door of Yan An's house, how did they know that this monitoring system had a back door in BT, if only the property was watching, then it would be impossible for their actions to attract attention.

This is also because the activities in Zhu Chi are a bit too comfortable, so that they are unguarded against it.

Gao Shenghan called Yan An back again, embarrassed and embarrassed.

"What's that...... Actually, they are not thieves.

It is a comrade of national security, responsible for protecting your safety.

Because I was afraid of disturbing your normal life, I didn't let them get close to you. ”

This answer surprised Yan An, and he thought that he needed to show a higher value than his father in order to attract Zhu Chi's attention.

Due to the lack of attention to current affairs, he only knows that the country is eager for development and rise.

But he didn't know how far that craving had reached.

In addition, his value judgment of the factorization algorithm is based on BT's vast database.

As a result, Yan An's perception of the value of the factorization algorithm was skewed, he knew that this thing was valuable, and he also knew that this thing solved one of the most difficult problems in the mathematics of the Blue Dome.

But he didn't think that solving this problem would give him comprehensive protection, and he always thought that the reward would be a pennant plus five hundred yuan.

Or send a certificate and give a bonus.

However, this is good news, at least the security issues have been resolved, and BT has previously strongly objected to his access to the knowledge in the database on the grounds that it is not secure.

Now that just a factorization algorithm can be protected by a special person, then after he comes up with more advanced and advanced technology, the protection he gets should gradually increase.

Yan Anyi on the phone was silent, which made Gao Shenghan a little flustered, "Please understand, we are here for your safety."

You should also know that if it is known that you have come up with an RSA effective search algorithm and are still working on it, I am afraid they will not work against you.

You don't want to join our institute, but we don't want that to happen.

Please believe that we have absolutely no ill will in this matter. ”

Gao Shenghan nervously explained to Yan An, because this was an action that he had never said hello, and he was afraid that it would make Yan An feel offended.

There was already a conflict today, the relationship had not had time to ease, and he found out about this matter, and he was really worried that the development of the situation would gradually get out of his control.

Especially Yan An's silence, he always had a feeling that a storm was brewing.

What he is most worried about now is that Yan An will have a bad opinion of them because of this incident, and then directly interrupt the "cooperation".

It's not that without Yan An, they can't continue to improve the RSA effective search algorithm, and they can't continue to expand the RSA effective search algorithm.

But in terms of Yan An's current personal ability, it has been proved from all sides that this is a rare talent.

What's more, he already has a clue about the factor factorization algorithm, and the loss caused by losing him is something that Gao Shenghan, the old director, Han Junmin and others are not willing to see.

It is true that as the 56th Research Institute of Zhu Chi's General Staff, their family has a great cause and many talents, and one more or less does not seem to have any impact.

But this kind of thing, what is needed is an attitude, one less talent today is nothing, tomorrow one less talent is nothing, so for a long time, what talent can they leave?

Even if you don't want to retain talent, how can you blame the country's brain drain.

After his explanation, Yan An still did not speak, and in the silence, Gao Shenghan's heart was gradually raised to his throat.

Half-ringing, Yan An over there finally spoke, "Is this because of the RSA effective search algorithm or the protection that the factorization algorithm wants to arrange for me?" ”

He didn't feel offended, because his life was never disturbed, and he would feel very relieved if the protection in the future could be like this.

"Both." Gao Shenghan replied cautiously, "Because you don't want to leave Nandu, and we have to ensure your safety, so we arranged it without permission, I'm very sorry." ”

"What about the factorization algorithm after it is figured out, will there still be protection?

Will you get the news out there? Will there be more protection after it is revealed?

If I don't crack passwords in the future, will there be protection? ”

"Eh, this ...... There should be all of them! His question surprised Gao Shenghan very much, and he didn't seem to be angry when he listened to the tone, which really relieved him.

"Rest assured, we value you as a person, not what you're about to produce.

If you need more protection, you can come to our institute and you will be fully protected. ”

Gao Shenghan made another temptation, but was unsurprisingly rejected by Yan An.

It's nothing to leave in a short time, but if you let him move the nest directly, it will be too troublesome.

He also knew that as long as they could produce results, they would continue to pay attention to themselves, in that case, there was no need to go to Liangxi, he could do the same in Nandu.
