No. 671 Big Data Investigation
Head tiao company meeting room.
Han Bin, Li Qin and Bao Xing rushed to the head tiao company and were arranged to rest in the conference room.
Han Bin is holding his mobile phone and browsing the page of the head tiao software.
In the past few days, Han Bin has been researching this software whenever he has time.
One of the things that struck him was that he felt like he was being watched by the software.
At the beginning, he watched any news on the head tiao software, and the software would push similar news, which was okay, and Han Bin could accept it.
But then it turned a little sour, and he used other software on his phone, such as search software, software monitoring.
He searched the Baiziyuan community with Gaode map, and when he opened the head tiao software, a lot of information related to the Baiziyuan community appeared.
For another example, Han Bin chatted with Wang Ting on WeChat, mentioning the catering industry, and the head tiao software will also push relevant news.
This is not the most terrifying, sometimes Han Bin feels that he has just mentioned something when chatting with people, and the head tiao software will also push, 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 header tiao software to turn on the microphone function when installing the software, and if he could really steal data through the microphone, it would be a little scary.
Sometimes, the head tiao software will also prompt him to authorize the video function, and Han Bin immediately refused, which is equivalent to bringing a body camera.
Through the use of these days, Han Bin can be regarded as having a thorough understanding of this software, so he came up with a new detection idea.
"Knock knock. 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 look, "Officer Han, I'm really sorry to keep you waiting, I did have something to do just now, and I was delayed." ”
Han Bin smiled, "It's okay. ”
Ni Yuanfeng was secretly relieved to see that Wang Xiao didn't come, and sat down next to the conference table, "Officer Han, what are your orders for coming today?"
"I don't dare to do it, I have a few questions for you. ”
You say. ”
"Does your software snoop on the owner's privacy?"
Ni Yuanfeng was stunned for a moment, he didn't expect Han Bin to ask like this, and quickly denied it, "No, of course not." ”
"Why did I browse some products on Taobao, and similar push links would appear on the head tiao software. ”
Ni Yuanfeng explained, "Officer Han, this is not our head tiao software snooping, but a product of the era of big data, now the data is all the same, your browsing data on other platforms will be recorded, and then they can achieve accurate delivery when they put information flow ads to the head tiao, this is a way of information flow advertising, which itself has little to do with the head tiao, the head tiao just provides a platform for advertising." ”
"The era of big data?"
"Yes. ”
"Yesterday, I searched for self-driving trips on Baidu, and it turned out that Tiao pushed me a lot of videos related to RV travel, how can this be explained? ”
"This ......" Ni Yuanfeng hesitated for a moment, "We do have some cooperation with Bai Du Company. ”
"What kind of cooperation law, how can cooperation betray the privacy of customers?" Han Bin asked rhetorically.
"No, no......" Ni Yuanfeng wiped the sweat from his forehead, "There are some agreements between our two companies, and it is true that there are not many things to say to the outside world." ”
Ni Yuanfeng's words changed, "Officer Han, you shouldn't have come here today for this matter, right?"
"You're right, this matter is really not in my hands, it's a big deal, I deleted your company's software afterwards. I'm here today to ask your company for help. ”
Ni Yuanfeng said secretly, your attitude is really not like this.
However, he didn't dare to say it explicitly, he just wanted to send this plague god away as soon as possible, "You said, if there is anything you need me to do, I will do my best to help." ”
"I'm very interested in your big data, and it's not bad to use it to solve crimes. Han Bin stood up and paced, "Help me use big data to accurately locate an account." ”
"Do you know the name of this account?"
"If I knew, I wouldn't have bothered to tell you so much. Han Bin thought about it, it was necessary to explain to him, only when the other party understood what he meant, could he better assist him.
"I went back and studied the account information of the person involved in the case you provided, and found that the summer hail account used by the murderer was only connected to two people in the near future, one is Lu Jingfang and the other is Wang Siyu. He hadn't read any of the other information, which was very abnormal. ”
First of all, he knew Lu Jingfang, and it was understandable to contact Lu Jingfang directly, but Wang Siyu was different, Wang Siyu was the victim he found through the head tiao software, and he must have browsed a large number of similar videos before identifying the target, but the account he used had no relevant records. ”
That only means that he still has an account of his own, which is used normally, and the account of Summer Hail is only used to contact the victim. ”
It is easy to understand if you replace the header tiao number with a mobile phone number.
The real-name system of a mobile phone number is your own, and you will use it normally to contact friends and relatives. Once this phone number was revealed, his identity was also revealed.
Therefore, the murderer will use other people's mobile phone numbers, which are 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 see 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 from you." ”
"Yes, it is the duty of every citizen to assist the police in their investigations. Ni Yuanfeng answered, and then went out to make arrangements.
After a while, Ni Yuanfeng walked in with the technician named Xiaoma, who was looking for this pony three times in a row, and he was also a skilled master.
Pony opened his laptop, crackled, and pushed his glasses, "Comrade policeman, I'm ready, you can just say the information about the target person." ”
"Construction site girl Xiaofang. ”
"More than 300,000 people have viewed her videos. ”
"A soft girl who loves fitness. ”
More than half a million people have viewed her videos, overlapping fans, more than 100,000 people. More correlation conditions are needed. ”
"Let's generate electricity together, Lu Jingfang, homicide, Mercedes-Benz, Zhou Jingjing, Tiannanyuan......" Han Bin said the key words of some cases.
The more conditions there are, the fewer people will be eligible.
Li Qin and Bao Xing watched from the sidelines and didn't interject, it was the first time they had seen a suspect locked up in this way.
When the pony was done, "five people were locked." ”
Han Bin continued, "This person's IP login address should be local. ”
"Smack," Pony tapped on the keyboard, "and two more." ”
"Get all their information out. 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
Origin, Koto Island
Mobile phone number, 1368238XXXX
Han Bin only glanced at it, "Call up the information of the next account as well." ”
Account name, Sister Xiaohua
Gender, female
Age, 24 years old
Origin, Koto Island
Mobile phone number, 158233XXXX
Li Qin walked over and took a look, "Isn't this a female user?" ”
Han Bin turned his head to look at Ni Yuanfeng on the side, "The gender should be something that can be filled in casually." ”
Ni Yuanfeng replied, "Yes, as long as the mobile phone number is bound, the others can be filled in casually, and we do not force customers to completely real-name information." ”
"Sister Li, notify the technical department and check the mobile phone number of the account name Sister Xiaohua. ”
Li Qin asked, "What about the fame of the account?"
"You don't have to look it up. ”
