Detective From the Future Chapter 671: Big data investigation
Head tiao company meeting room.
Han Bin, Li Qin and Bao Xing rushed to the tiao company and were arranged to rest in the conference room.
Han Bin is browsing the tiao software page with his mobile phone.
In the past few days, Han Bin has been studying this software as long as he has time.
One thing that impressed him was that he felt he was being monitored by this software.
In the beginning, if he reads any news on the tiao software, the software will push similar news, which is okay, and Han Bin can also accept it.
But then it changed a bit. He used other software on his phone, such as search software and software monitoring.
He searched the Baiziyuan community on the Gaode map, and when he opened the Tiao software, a lot of information related to the Baiziyuan community appeared.
For another example, Han Bin chatted with Wang Ting on WeChat and mentioned the catering industry. The head tiao software will also push relevant news.
This is not the most terrible. Sometimes Han Bin feels that he just mentioned something when chatting with people, and the tiao software will also push it. Han Bin even suspects that this software can eavesdrop on data through a microphone.
Of course, this is just 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 you can really steal data through the microphone, it would be a bit scary.
Sometimes, the tiao software will prompt him to authorize the video function, and Han Bin immediately refused, which is equivalent to bringing a body camera.
Through these days of use, Han Bin can be considered to have a thorough understanding of this software, and thus came up with a new detection idea.
"Boom." There was a knock on the door outside, and then Ni Yuanfeng opened the door and walked in.
As soon as he entered the door, Ni Yuanfeng showed an apologetic look, "Sergeant Han, I'm so sorry to keep you waiting for a long time. I did have something to do just now and it was delayed."
Han Bin smiled, "It's okay."
When Ni Yuanfeng saw Wang Xiao not coming, he secretly breathed a sigh of relief, and sat next to the conference table, "Sergeant Han, what are your orders for coming today?"
"I didn't dare to be told, I have a few questions for you."
"You said."
"Does your software spy on the owner's privacy?"
Ni Yuanfeng was stunned for a moment. He didn't expect Han Bin to ask this, and quickly denied, "No, of course not."
"Why I browsed some products on Taobao, similar push links also appeared on the tiao software."
Ni Yuanfeng explained, "Sergeant Han, this is not our head tiao software snooping, but a product of the big data era. Now the data is connected, and your browsing data on other platforms will be recorded, and then they The accurate delivery can only be achieved when the information flow advertisement is delivered to tou tiao. This is a way of information flow advertising, which itself has little to do with tou tiao. Tou tiao only provides a platform for advertising."
"Big Data Era?"
"Yes."
"Yesterday, I searched for self-driving tours on Baidu. As a result, tiao posted me a lot of videos related to RV travel. How do you explain this? Baidu should not place ads on your software, right?"
"This..." Ni Yuanfeng hesitated, "We do have some cooperation with Baidu Company."
"How is the cooperation law, how can cooperation betray the customer's privacy?" Han Bin asked rhetorically.
"No, no..." Ni Yuanfeng wiped the sweat from his forehead. "There are some agreements between our two companies, but it is really not a big deal."
Ni Yuanfeng turned around, "Police Officer Han, shouldn't you be here today for this, right?"
"You are right, this matter is indeed out of my control, big deal, I deleted your company's software afterwards. I am here today to ask your company for help."
Ni Yuanfeng secretly said, your attitude is really different.
However, he did not dare to say clearly, he just wanted to send away the plague **** earlier, "You said, if there is anything I need to do, I will do my best to help."
"I am very interested in your big data, and it is also good for solving cases." Han Bin stood up, paced and walked, "Help me use big data to accurately locate an account."
"Do you know the name of this account?"
"If you know, I won't bother to tell you so much." Han Bin thought for a while. It is necessary to explain to him. Only when the other party understands what he means can he better assist. Own.
"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 was only in contact with two people in the near future, one is Lu Jingfang and the other is Wang Siyu. He has not read it. Any other information, this is very abnormal."
"First of all, he knew Lu Jingfang, and it was excusable to contact Lu Jingfang directly, but Wang Siyu was different. Wang Siyu was the victim he found through the Tiao software. Before determining the target, he must have browsed a lot of similar videos, but There is no record of the account he used."
"That only means that he still has an account that belongs to him. That account is for normal use, while the summer hail account is only used to contact the victim."
It will be easier to understand if you replace the first tiao number with a mobile phone number.
A real-name system for a mobile phone number is its own, and will be used normally to contact friends and relatives. Once the phone number was exposed, his identity was also exposed.
Therefore, the murderer will use the mobile phone number of other people. This mobile phone number 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, and quickly understood what Han Bin meant.
"Can it be done?"
"You can try."
Han Bin said politely, "Mr. 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 was looking for the Xiao Ma three times in a row. It was also a great skill.
Little Ma opened the laptop, cracked it, pushed his glasses, "Comrade police, I'm ready, you can just tell me the information about the target person~IndoMTL.com~worksite girl small Fang."
The technician Xiao Ma performed it, "More than 300,000 people have viewed her video."
"Soft girl who loves fitness."
"More than half a million people have viewed her video, and there are more than 100,000 overlapping fans. More association conditions are needed."
"Let's generate electricity together, Lu Jingfang, the murder case, Mercedes-Benz, Zhou Jingjing, Tiannanyuan..." Han Bin said the key words of some cases.
The more conditions, the fewer the number of people who meet.
Li Qin and Bao Xing watched from the sidelines without interjecting. It was the first time they saw a suspect locked in this way.
After Xiao Ma finished the operation, "Five people have been locked."
Han Bin continued, "This person's IP login address should be local."
"Pa" Xiao Ma knocked on the keyboard, "There are two more people."
"Call up their information." Han Bin walked to the screen and began to check the information of the two accounts.
Account name, Wangjiang None
Gender, male
Age, 26 years old
Hometown, Qindao
Mobile phone number, 1368238XXXX
Han Bin only glanced at it, "Call out the information of the next account."
Account name, Sister Xiaohua
Gender, female
Age, 24 years old
Hometown, 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 aside, "You can fill in the gender at will."
Ni Yuanfeng replied, "Yes, as long as the mobile phone number is bound, the others can be filled in at will. We do not force customers to complete the real-name information."
"Sister Li, notify the technical department to check the phone number of the account name Xiaohua sister."
Li Qin asked, "Where is the account name Jiang Wu?"
"No need to check this."
