Detective from the future

Chapter 669 Chapter 671 Big Data Investigation

Head to the company meeting room.

Han Bin, Li Qin and Bao Xing rushed to the head office and were arranged to rest in the meeting room.

Han Bin was browsing the page of the head-tiao software with his mobile phone.

In the past few days, Han Bin studies this software whenever he has time.

Among them, one thing impressed him deeply, he felt that he was being monitored by this software.

In the beginning, when he read any news on the head tiao software, the software would push similar news, which was fine, and Han Bin could accept it.

But then something changed. When he used other software on his mobile phone, such as search software, WeChat, etc., he would also be monitored by the head-tiao software.

He searched the Baiziyuan community with the AutoNavi map, and when he opened the Tiaotiao software, a lot of information related to the Baiziyuan community appeared.

For another example, when Han Bin chatted with Wang Ting on WeChat and mentioned the catering industry, the head tiao software would also push related news.

This is not the scariest thing. Sometimes Han Bin feels that he just mentioned something when chatting with people, and the head tiao software will push it. Han Bin even suspects that this software can eavesdrop on data through the microphone.

Of course, this is just a suspicion.

Han Bin himself can't remember whether he authorized the head-tiao software to turn on the microphone function when installing the software. If it is possible to steal data through the microphone, it would be a bit scary.

Sometimes, the head-tiao software will prompt him to authorize the video function, but Han Bin immediately refuses, which is equivalent to carrying a body camera.

Through these days of use, Han Bin had a thorough understanding of the software, and thus came up with a new idea for detection.

"Dong dong." There was a knock on the door outside, and then Ni Yuanfeng pushed the door and walked in.

As soon as he entered the door, Ni Yuanfeng showed an apologetic expression, "Officer Han, I'm really sorry for keeping you waiting. I did have something to do just now, so I was delayed."

Han Bin smiled, "It's okay."

Seeing that Wang Xiao didn't come, Ni Yuanfeng breathed a sigh of relief, and sat down beside the conference table, "Officer Han, what do you order today?"

"I dare not obey the order, but I want to ask you a few questions."

"You say."

"Is your software spying on the owner's privacy?"

Ni Yuanfeng was stunned for a moment, he didn't expect Han Bin to ask such a question, and quickly denied it, "No, of course not."

"Why do I browse some products on Taobao, and there will be similar push links on the top tiao software."

Ni Yuanfeng explained, "Officer Han, this is not our spy software, but a product of the era of big data. Now the data is interlinked. Your browsing data on other platforms will be recorded, and then they will give you a Only when tiao puts in-feed advertisements can it achieve precise placement, which is a way of in-feed advertisements, which itself has little to do with head tiao, which only provides a platform for advertising.”

"Big Data Era?"

"Yes."

"Yesterday, I searched for self-driving tours on Baidu, and as a result, a lot of videos related to RV travel were pushed to me at the top of the list. How do you explain this? Baidu probably won't place ads on your software, right?"

"This..." Ni Yuanfeng hesitated for a moment, "We do have some cooperation with Baidu Company."

"What kind of cooperation method, how does cooperation sell the privacy of customers?" Han Bin asked back.

"No, no..." Ni Yuanfeng wiped the sweat from his forehead, "There are some agreements between our two companies, and it's really inconvenient to tell the outside world."

Ni Yuanfeng changed the subject, "Officer Han, you didn't come here today for this matter, did you?"

"You're right. I'm really not in charge of this matter. It's a big deal. I deleted your company's software afterwards. I'm here today to ask your company for help."

Ni Yuanfeng thought to himself, your attitude is really out of character.

However, he didn't dare to say it clearly, he just wanted to send the God of Plague away as soon as possible, "Say, if there is anything I need to do, I will do my best to help."

"I'm very interested in your big data, and it's good for solving crimes." Han Bin stood up and walked around. "Help me use big data to pinpoint an account."

"Do you know the name of this account?"

"If I knew, I wouldn't bother to tell you so much." Han Bin thought for a while, and it was necessary to explain to him. Only when the other party understood what he meant, could he help him better.

"The account information of the person involved in the case you provided, I went back and studied it carefully, and found that the summer hail account used by the murderer has only been in contact with two people in the near future, one is Lu Jingfang and the other is Wang Siyu. He has not seen any other accounts. Information, this is very abnormal."

"First of all, he knows Lu Jingfang, and it is understandable to contact Lu Jingfang directly, but Wang Siyu is different. Wang Siyu is the victim he found through the head-tiao software. Before determining the target, he must have browsed a lot of similar videos, but he used There is no relevant record of the account.”

"That only shows that he still has an account of his own, which is used normally, and Xia Rihail's account is only used to contact the victim."

It will be easy to understand if the first tiao number is replaced with a mobile phone number.

A real-name mobile phone number is your own, and you can use it normally to contact friends and relatives.Once this mobile phone number is exposed, his identity is also exposed.

Therefore, the murderer will use other people's mobile phone number, which is only used to contact the victim, so that even if the police find the mobile phone number, they will not be able to find the user.

What Han Bin wants to check now is the murderer's real-name account.

"I understand what you mean." Ni Yuanfeng originally studied big data, so he quickly understood what Han Bin meant.

"Can it be done?"

"You can try."

Han Bin said politely, "President Ni, then you will suffer."

"Yes, it is the duty of every citizen to assist the police in the investigation." Ni Yuanfeng responded, and then went out to make arrangements.

After a while, Ni Yuanfeng walked in with the technician named Xiao Ma. He had been looking for Xiao Ma three times in a row, and he seemed to be a skilled technician.

Xiao Ma turned on the laptop, operated it cracklingly, and pushed his glasses, "Comrade policeman, I'm ready. You can just provide the information about the target person."

"Xiaofang, a girl from the construction site."

The technician Xiao Ma performed some operations, "More than 30 people have viewed her video."

"A soft girl who loves fitness."

"More than 50 people have viewed her video, and there are more than a hundred thousand people who have overlapping fans. More related conditions are needed."

"Let's generate electricity together, Lu Jingfang, homicide, Mercedes-Benz, Zhou Jingjing, Tiannanyuan..." Han Bin said all the key words of some cases.

The more conditions there are, the fewer people are eligible.

Li Qin and Bao Xing watched from the sidelines without interjecting. This was the first time they saw a suspect being locked in this way.

After Xiao Ma finished the operation, "Five people were locked."

Han Bin continued, "This person's IP login address should be local."

"Crack" Pony tapped the keyboard, "There are two more people."

"Call out their information." Han Bin walked to the screen and began to check the information of the two accounts.

Account name, Wangjiang no

Sex: Male
age, 26

Native place, Qindao

Mobile phone number, 1368238XXXX
Han Bin only glanced at it, "Call out the information of the next account."

Account name, Miss Xiaohua

Gender: Female
age, 24

Native place, Qindao

Mobile phone number, 158233XXXX
Li Qin walked over and took a look, "Isn't this a female user?"

Han Bin turned his head and looked at Ni Yuanfeng who was beside him, "Gender should be optional."

Ni Yuanfeng replied, "Yes, as long as the mobile phone number is bound, the rest can be filled in as you like. We have not forced customers to complete real-name information."

"Sister Li, notify the technical department to check the mobile phone number of the account name Miss Xiaohua."

Li Qin asked, "What about Jiang Wu's account name?"

"There is no need to check this."
