Gu Kaiwen thought silently, just like Yuan Xiaoyu said, his current layout was only to rescue the panda, but he couldn't catch the poachers.

Although Gu Kaiwen doesn't know about the anonymous community, nor does he know these guys hidden in the anonymous community, Gu Kaiwen knows very well that if he proposes a face-to-face transaction, I'm afraid that this time the transaction will be directly suspended.

The most important thing about anonymous community and anonymous transactions is security!

If you want to trade face-to-face, what kind of anonymous community and anonymous transaction are you going to engage in?

"Classmate Yuan, do you have any solution to this problem?" Gu Kaiwen asked.

Yuan Xiaoyu was silent for a moment before responding, "Master Zhai, I think saving the panda is already a good result, and we only need to pay a deposit of thirty percent to save the panda, it should be a good result, right?"

Gu Kaiwen frowned, "This result is indeed a good result, but I can't accept that poachers go unpunished." Is there any way to catch the poachers?"

"There are certainly solutions, but there are too many resources involved, and there is no guarantee of 100% success. Mr. Gu, do you want to give it a try?" Yuan Xiaoyu asked rhetorically.

"Tell me what to do first. Gu Kaiwen responded.

Yuan Xiaoyu explained, "Modern society has entered the era of big data, we live in this era of big data, we will inevitably leave traces, as long as we have enough resources, we can find clues." ”

"For example?" Gu Kaiwen asked rhetorically.

Yuan Xiaoyu gave an example, "For example, some girls always like to check the chat history of their boyfriend's mobile phone, but the chat history is easy to delete, and men generally do not ignore this information. ”

Gu Kaiwen was silent and did not speak.

Yuan Xiaoyu continued, "Taking WeChat as an example, in this era of big data, we can't find chat records, but we can view the group list of Moments. Another example is the red packet sending record, because the red packet record cannot be deleted, you only need to check the red packet sending record, as long as there is a problem, you will definitely be able to find the problem. ”

"There are also group purchase movie ticket records, takeaway order address records, photo album recycle bins, shopping website records, hotel membership and reservation records, and even game friends, etc., all of which can be found out of the problem. In this era of big data, as long as there are records, as long as you don't pay attention to deleting the records, you can be tracked and located. Yuan Xiaoyu explained.

Gu Kaiwen and Fan Yingjun glanced at each other, and both understood what the other meant.

Fan Yingjun said directly, "Classmate Yuan, you are so shrewd, can you find a boyfriend?"

"That's why I'm single!" Yuan Xiaoyu responded.

Gu Kaiwen secretly praised himself, this Yuan Xiaoyu is very good!

If Gu Kaiwen's girlfriend is also so good, even if Gu Kaiwen doesn't have these behaviors, he will feel a little too terrifying, right, there is no private space at all?

But this kind of operation can indeed find the cheating behavior of the scumbag!

It's a learning experience!

Of course, male friends can also learn to delete all records.

"Ahem!" Gu Kaiwen coughed twice, "How can you query poachers through big data now?"

"We now have a very important piece of information that the poachers will provide us with a video surveillance that we can track, and through this video surveillance, we will be able to determine the exact location of the pandas. Yuan Xiaoyu explained.

Gu Kaiwen nodded, although he was not proficient in computers, he also knew this, "And then?"

"Then we need big data, and we need the base station authority of the communication operator in the corresponding location. Let me first explain, my lord, my technology cannot hack into the base station of a communication operator through hacking. Therefore, this one authority still needs to be solved by the fasting master. Yuan Xiaoyu explained the situation.

Gu Kaiwen nodded, "No problem, you continue." ”

"We have obtained the base station permission of the communication operator, and we can search for information in the base station server and read all the mobile phone numbers connected to the base station at the corresponding location. Yuan Xiaoyu explained.

"After reading all the mobile phone numbers, we analyze the link time through the base station server, and it will take at least a certain amount of time for the poachers to set up surveillance in the corresponding location. So their mobile phone number will definitely stay in the corresponding area, but they are not frequent visitors in the corresponding area, through the cross-comparison of filter conditions, we can get a small number of phone number lists, and then through the real-name system of phone numbers, the corresponding good owner will be found. Yuan Xiaoyu responded.

Gu Kaiwen put forward a different opinion, "What if their mobile phone number is fake, such as the mobile phone number handled with someone else's ID card?"

"It's really possible!" Yuan Xiaoyu responded, "so we have a second plan." ”

"Oh?" Gu Kaiwen looked at Yuan Xiaoyu suspiciously.

"The anonymous seller just said that they need a day to prepare a traceable surveillance video, so we can judge that they need a day to buy the corresponding equipment, because it is a day, naturally it can't be online shopping, and online shopping is easy to leave records, I guess they should be in the real world purchase. Yuan Xiaoyu analyzed and explained.

"So what?" Gu Kaiwen asked rhetorically.

"Combined with the situation of our first step, we already know the target city, and then we compare and search the list of numbers just obtained in the internal network of the communication operator in the corresponding city, as long as the corresponding number appears in the area where the monitoring equipment is sold in the city before, we can cross-lock the target!" Yuan Xiaoyu said the plan.

"In order to accurately confirm the identity of the poachers, we can also obtain the authority of the city's public safety monitoring system, so as to retrieve the monitoring records of the corresponding area, and then cross-compare the monitoring records, we can find the people who appear together in the two areas, that is, the poachers we are looking for. Yuan Xiaoyu said with a radiant look.

Gu Kaiwen and Fan Yingjun glanced at each other again, both of them had a chilling feeling, fortunately their girlfriend is not a god of computer technology, if so, it would be a little scary, right?

After all, there's no even basic privacy, and it's scary to think about.

This era of big data with grass eggs!

Fan Yingjun couldn't help but complain, "Classmate Yuan, are you all so good at learning computers?"

Yuan Xiaoyu nodded, "Of course!"

"Fortunately, I don't have an ex-girlfriend from the computer department!" Fan Yingjun secretly breathed a sigh of relief, if there is an ex-girlfriend from the computer department, wouldn't it be the end?
