The old man knocked on the door, and after getting Lin Wan'er's answer, he opened the door and walked in slowly.
And in his hand, he was holding a laptop.
He placed the computer in front of Lin Wan'er and said: "Miss, I have found all the information you asked me to check. There are a total of 2,128 men with the surname Ye and Chen Qingchen across the country. Three
Under ten years old, 879 people;"
"There are a total of 540 men with the surname Ye and Chen in the country, and a total of 213 men under the age of 30;"
"There are only twenty men named Ye and Chenchen Chen in the country, and there are only seven men under the age of thirty."
"In addition, I used Pinyin to retrieve the information of all men under the age of 30 whose surname is Ye and whose first name is pronounced "Ye", a total of one hundred and seventy-two people."
After that, he added: "All the information on these leaves is here, please take a look."
"Okay." Lin Wan'er nodded, placed her fingers on the direction keys, and quickly browsed every relevant information about Ye Chen.
In the past few days, she had clearly remembered Ye Chen's appearance by repeatedly watching surveillance videos. Therefore, the main comparison method at the moment was to use ID photos to check the information she saw with the Ye Chen she saw.
, whether they are the same person.
But the strange thing is that after browsing through everyone's information, he didn't find the Ye Chen who saved him that night.
Lin Wan'er frowned and couldn't help but ask the old man: "Is all Ye Chen's information here?"
"Yes." The old man nodded: "Everything that can be found is here."
Lin Wan'er couldn't help but secretly wonder: "Did he lie to me then?"
Thinking of this, she couldn't help but shake her head: "It shouldn't be... He must have been absolutely sure that he could erase my memory. In this case, there was no need for him to lie, right? Moreover, since he dared to tell the Qinghui
There is no way you would not dare to reveal your true name to me in that situation..."
Seeing Lin Wan'er frowning and saying nothing, the old man couldn't help but ask: "Miss, do you have any questions? If you have any other clues, you can tell me. One more clue will give me a better grasp."
Lin Wan'er shook her head dejectedly and murmured: "There are no other clues. I only know that his name is Ye Chen."
The old man smacked his lips: "Everyone named Ye Chen, the information is here. If he didn't lie, could he be an overseas Chinese? Although his name is Ye Chen, he is also Chinese, but his nationality is in another country?"
Lin Wan'er said: "He said he is Chinese, but this does not rule out the situation you mentioned. After all, many overseas Chinese have a strong sense of identity with their motherland, and they will say that they are Chinese to the outside world. But if that is the case,
There are more than 200 countries in the world, so I can only look for 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, then said: "Encryption does happen. Information about people with special identities will be encrypted. However, in order to ensure that this encrypted information is not detected, the system itself cannot directly access it.
Get the encrypted content."
Lin Waner asked him: "What is the general encryption logic?"
The old man said: "As far as I know, there are two encryption logics. One is that his identity information is completely erased from the system and the information is stored in another isolated system. The latter will not have any connection with the network.
Any connection, that is to say, his real information only exists in the latter system, and no one from the outside can find any clues;"
As he spoke, the old man added: "The other one is more complicated. This person has a set of real identity information, but this set of information has been encrypted in the system, and it has become a one-way identity to a certain 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 register, marriage certificate and other ID documents are all real, and the ID number is also real, but if anyone in the system wants to
Even if you search vaguely for his information, you won't be able to find it. For example, if I want to check who is named Ye Chen in the country, his information will not appear in the results returned by the system. I want to check all the surnames in the country.
Ye's personal information will not be included in the results. Even if we retrieve the information of hundreds of millions of men across the country, he will not be included in the results."
"If you want to check his information, there are two conditions. First, you must know his name and his accurate ID number. Only when these two pieces of information are completely correct can you find out his information;"
"In this way, it basically eliminates other people's wide-net searches, because if you really need to use this system to find someone in a huge crowd, you can't know his ID number. If you
If you already know his ID number, you already have 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 well can't find him in the system, and people who know him can't come back to the system to check his information. Even if they know him
People came to check and entered their names and ID numbers, and the results they got were true and there were no clues."
"Yes." The old man nodded and said: "Some people with very, very special identities will use this method to hide, so that a person can truly hide in the city. Everything is true, but everything is different.
This makes it impossible for people who have ulterior motives for him to verify."
As he spoke, the old man added: "Such a person, using his own identity,
