The old man knocked on the door, and after receiving Lin Wan'er's approval, he pushed open the door and walked in slowly.
And in his hand, he also held a laptop computer.
He put the computer in front of Lin Wan'er and said, "Miss, the information you asked me to check has been found. The country's surname is Ye, named Qingchen Chen, a total of 2,128 people, three
Under ten years old, eight hundred and seventy-nine people;”
"There are 540 men in the country whose surname is Ye and whose name is Xingchen, and those under the age of thirty are 213 people;"
"There are only twenty men in the country whose surname is Ye and whose name is Dust Dust, and only seven are under the age of thirty."
"In addition, I used pinyin to retrieve all the information of men under the age of thirty who pronounced the surname Ye and names as pronounced by Ye, a total of 172 people;"
After saying that, he said, "All the information about these leaves is here, please check it out."
"Okay." Lin Wan'er nodded, put her finger on the arrow keys, and quickly browsed the relevant information of each Ye Chen.
In the past few days, she has long remembered Ye Chen's appearance by repeatedly watching the surveillance video. Therefore, the main method of comparison is to check the information she saw through the ID photo and meet the Ye Chen she saw.
, is it the same person?
But strangely, everyone browsed all the information, but they didn't find the Ye Chen who saved him that night.
Lin Wan'er frowned and couldn't help but ask the old man: "Are all Ye Chen's information here?"
"Yes." The old man nodded: "All you can find it here."
Lin Wan'er couldn't help but think to herself: "Can he lied to me at that time?"
Thinking of this, she couldn't help but shake her head: "No... He must have been very sure that he could erase my memory. In this case, he had no need to lie, right? Moreover, since he dared to go to the Poqing Association
If you start, you can't dare to reveal your real name to me under that situation..."
When the old man saw Lin Wan'er frowning and said nothing, he couldn't help asking: "Miss, are there any problems? If you have any other clues, you can also tell me that one more clue can make you more sure."
Lin Wan'er shook her head a little depressedly and murmured: "There is no other clue, I only know that his name is Ye Chen."
The old man smacked his lips: "All the people named Ye Chen are here. If he didn't lie, would he be an overseas Chinese? Although his name is Ye Chen and he is also a Chinese, his nationality is in other countries?"
Lin Wan'er said, "He said he is a Chinese, but he can't rule out the situation you are talking about. After all, many overseas Chinese have a strong sense of identity with their motherland, and they will also say that they are a Chinese, but if that's the case,
In more than 200 countries around the world, I can only find a needle in a haystack…”
Speaking of this, Lin Wan'er suddenly raised her head unwillingly and asked the old man: "Is there a possibility that his identity has been encrypted in the system?"
"Encryption?" The old man frowned and thought for a while, and said, "There is indeed a situation of encryption. People with special identities will be encrypted. However, in order to ensure that these encrypted information are not found, the system itself cannot directly adjust it.
Get encrypted content.”
Lin Wan'er asked him: "What is the general encryption logic?"
The old man said: "As far as I know, there are two types of encryption logic. One is that his identity information is completely erased from the system and stored in another isolated system, which will not have any connection with the network.
Any connection, that is, its real information only exists in the latter system, and no one in the outside world can find any clues;"
As he said that, the old man said: "The other kind is more complicated. This person himself has a set of real identity information, but this set of information has been encrypted in the system and has become a one-way identity to some extent."
Lin Wan'er asked: "What does one-way mean?"
The old man explained: "One-way means that his ID card, his passport, driver's license, even household registration book, marriage certificate and other ID cards are all real, and the ID number is also real, but anyone in the system wants to
If you search for his information in a vague way, you can't find it. For example, I want to check who is named Ye Chen in the country. Then the results returned by the system will not appear. I want to check all surnames in the country.
Ye’s people’s information will not be there. Even if we call out the information of hundreds of millions of men across the country, there will not be there in it;
"If you want to query his information, there are two conditions. First, you must know his name and his accurate ID number. Only when both information are completely correct can your information be found;"
"In this way, others are basically eliminated from searching for others in a wide net, because like you, you really need to use this system to find someone in the vast crowd. You cannot know his ID number, if you
If you know his ID number, it means that you have already mastered his real information, so you don’t need to use this system to cast a wide net.”
Lin Wan'er sighed: "In this way, this encryption method is still very smart. People who don't know him can't find him in the system, and people who know him can't come to the system to check his information again, even if they know him
People come to check and enter their name and ID number. The results are also real, and there is no clue."
"Yes." The old man nodded and said, "Some people with very special identities will use this method to hide, so that a person can truly be hidden in the city. Everything is true, but everything is also true.
It makes it impossible for people who have ulterior motives to verify it."
As he said that, the old man said again: "A person like this,
