"I'm thinking of you." Shen Hong emerged from behind Yan Xinyi and startled her.

"You're going to scare me to death!" Yan Xinyi exaggeratedly patted his chest with his hand, "In this kind of eerie place, I thought it was a ghost." ”

"Don't be funny, you're still afraid of ghosts." Shen Hong smiled, "Who doesn't know that our Public Security Bureau is famous for his bold face, and he is not afraid of heaven and earth." is upright, and I am afraid that I will take a detour if I see a ghost. ”

Yan Xinyi chuckled, "You are also engaged in computers, why are you so likeable, but he is so annoying." ”

"Him?" Shen Hong was slightly stunned, and immediately reacted, "You mean Zhong Kenan who looks like a stone in a pit, what a coincidence, I came to you to talk about him." ”

"The stones in the pit are hard and smelly, hahaha......" Yan Xinyi thought of Zhong Kenan's expressionless face and arrogant and rude appearance, and felt that it was really so appropriate, "The only one who can hurt people like this is probably Song Jingyan." ”

"But no, when Brother Song interrogated him in the morning, he was so angry that he choked. But personally, I can't believe that a god-level figure in the field of computer science like him would be a murderer. Shen Hong has sincere admiration for Zhong Kenan, "I think there must be a reason why he is so uncooperative and hostile to the police." I checked, and sure enough. ”

"Tell me why." Yan Xinyi asked urgently.

Shen Hong said in detail that about a year ago, Zhong Kenan went to the Internet Supervision Brigade of the Public Security Bureau to report that his grandmother had suffered from Internet phone fraud. Grandma Zhong is a retired teacher, and one day Grandma Zhong suddenly received a call from someone claiming to be a public security officer, who had her detailed personal information, claiming that the public security organs had found that her bank account was suspected of money laundering and wanted to investigate it. Subsequently, Grandma Zhong received a number of calls that were displayed as numbers in different areas, in fact, these were all made from Internet phones that could be set at will, and several people partnered to play different roles such as "public security police" and "prosecutors", each of whom claimed that Grandma Zhong's account was used to launder money in many parts of the country, and that her account should be "checked".

Grandma Zhong was so frightened that she called Zhong Kenan at that time, but it happened that he was busy with a very important project, and he couldn't even sleep, so she just said that she would wait for him to go home, and hung up the phone in a hurry. The scammer's phone calls came one after another, and in a hurry, Grandma Zhong told the "case-handling staff" about her situation, and opened a new online bank account at the bank according to the other party's requirements, and transferred all her deposits, financial management and insurance funds to this account. In order to "cooperate with the account clearance", he also told the "case-handling personnel" the account number, password and dynamic verification code. The scammer quickly transferred 900,000 yuan of funds in the account through a third-party payment platform.

It was noon the next day when Zhong Kenan returned home, and after listening to what his grandmother said, he immediately understood that he had been deceived and immediately reported the case, but it was not so easy to recover the stolen money. Grandma Zhong was very old and in poor health, but after learning that she had been deceived, she was anxious and angry, resulting in a sudden cerebral hemorrhage and death after ineffective rescue. At that time, the mastermind of the fraud was Cai Aqi, and he also had several accomplices. They deceived many people, and before Zhong Kenan reported the case, the Internet Supervision Brigade had received a number of similar reports, and the police tracked down them for more than a year before finding their den.

"I see." Yan Xinyi sighed sympathetically, "He resented that the police failed to solve the case quickly and seek justice for his dead grandmother, so he relied on himself to track it down through big data analysis." ”

"He's really better than us. It took us a year and a half, and it only took him just over half a year to do it. Shen Hong said sincerely, "But he can't completely negate our efforts because of this." His enemies were the crooks, not the police. ”

"Or how about the stones in the pit." Yan Xinyi couldn't help but smile again, "Thank you, you came to tell me." ”

"I knew this information would definitely be useful for your portrait, so I'll tell you as soon as possible. No matter what others think, I am firmly on your side. Shen Hong entered the Public Security Bureau two years earlier than Yan Xinyi, and after Yan Xinyi joined the company, the two were of the same age, had similar interests and hobbies, and soon became good friends. Although Shen Hong is only a "cyber policeman", he is very interested in criminal psychology portraits and often asks Yan Xinyi for advice.

"Oh yes, how exactly is big data analytics analyzed?" Yan Xinyi was curious about this.

Shen Hong said that the principle of big data is, for example, if a person is defrauded by an Internet phone, he reports the phone to Zhong Kenan's company's platform, and thousands of people are similar, and they report it if they are fooled, so that the company's background has a large number of sample data of Internet fraud calls, which can be checked when it is opened, and Zhong Kenan found Cai Aqi and their dens through this method.
