Door-to-door dragon son-in-law

Chapter 2474 Encryption Logic
10 minute later.

The old man knocked on the door, and after getting Lin Wan'er's consent, he opened the door and walked in slowly.

And in his hand, there was a laptop.

He placed the computer in front of Lin Wan'er, and said, "Miss, I have already found all the information you asked me to check. There are 120 men in the whole country whose surname is Ye and whose name is Qingchen Chen. Those who are under 30 years old , 870 nine people;”

"There are a total of 540 men with the surname Ye and the name Chen Xingchen across the country, and a total of 30 men under the age of 210;"

"There are only 20 men with the surname Ye and the name Chen Duchen in the whole country, and there are only seven men under the age of 30."

"In addition, I used pinyin to retrieve the information of all men under the age of 30 with the surname Ye and the first name pronounced chén, a total of 170 people;"

After finishing speaking, he said again: "All the information about Ye Chen is here, please have a look."

"Okay." Lin Wan'er nodded, resting her fingers on the arrow keys, and quickly browsed through every piece of information about Ye Chen.

In the past few days, she has already remembered Ye Chen's appearance clearly by watching the surveillance video repeatedly. Therefore, the main way of comparison at the moment is to check the information she has seen through the ID photo, and Ye Chen she saw. , whether they are the same person.

But the strange thing is that after browsing all the information of everyone, he didn't find the Ye Chen who saved him that night.

Lin Wan'er frowned, and couldn't help asking 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 thinking to herself: "Could it be that he lied to me then?"

Thinking of this, she couldn't help shaking her head: "It shouldn't be... He must have been fully sure that he could erase my memory at that time. In this case, there is no need for him to lie? Besides, since he dared to tell Po Qinghui It is impossible for you not to dare to reveal your real name to me under such circumstances..."

Seeing that Lin Wan'er frowned and said nothing, the old man couldn't help asking: "Miss, is there any question? If you have any other clues, you can also tell me. One more clue will give me a better grasp."

Lin Wan'er shook her head dejectedly, and murmured: "I don't have any 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, would he be an overseas Chinese? Although his name is Ye Chen, he is also Chinese, but his nationality is in other countries?"

Lin Wan'er said: "He said that he is from Huaxia, but it doesn't rule out the situation you said. After all, many overseas Chinese have a strong sense of identity with their motherland, and they will say that they are from China, but if that is the case, There are more than 200 countries in 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 about it, and said: "There are indeed cases of encryption. The relevant information of people with special identities will be encrypted, but in order to ensure that these encrypted information will not be found out, the system itself cannot directly adjust Get the encrypted content."

Lin Wan'er asked him: "What is the general encryption logic like?"

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 system that is isolated from each other. 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 outside can find any clues;”

As he said that, the old man continued: "The other 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 it has become a one-way identity to some extent."

Lin Waner 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 booklet, marriage certificate and other ID documents are all real, and the ID number is also real, but if anyone in the system wants to I can't find his information by fuzzy query. For example, if I want to check who is named Ye Chen in the whole country, his information will not appear in the results returned by the system. The information about Ye’s people will not include him in the result, even if we pull out the information of hundreds of millions of men across the country, there will not be him in it;”

"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 information are completely correct can you find out his information;"

"In this way, it basically prevents other people's wide-spread searches, because like you, if you really need to use this system to find someone in a vast crowd, you can't know his ID number. If you Knowing his ID number means that you already have his real information, so you don’t need to use this system to cast a wide net.”

Lin Wan'er sighed: "Speaking of which, this encryption method is still very clever. People who don't know him well can't find him in the system, and people who know him can't check his information in the system again. People come to check, input their name and ID number, and the results are real, and they can’t find any clues.”

"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 hide in the city, everything is true, but everything is true. It makes it impossible for those who have ulterior motives to verify him."

As he said that, the old man said again: "For such a person, using his own identity, not only does he not have to worry about being found out by others, but his life will not be affected in any way."

"Because apart from what I just said, his information can only be found out by his name and ID number. All his documents are actually one-way inquiry channels;"

"For example, if a policeman checks his ID card on the road, as long as the policeman uses a device to read his ID card, he can check all his information in the system. In this way, the policeman will not find any abnormalities;"

"If he wants to fly, as long as he uses the correct name and ID card when buying the ticket, he can check in smoothly with the ID card;"

"If he wants to go abroad, then use his name and passport number to book a ticket, and then he will be able to exit the customs smoothly with his passport;"

"However, if anyone wants to look up him through the information registered on the plane, it will be impossible to find out. If you want to search for someone named Ye Chen who has flown in China, but you only know his name , then his information will not be displayed."

Lin Wan'er's two willow leaf-like eyebrows were slightly clustered in the middle, her expression was solemn and worried.

After hesitating for a moment, she asked the old man: "It doesn't matter whether the person I'm looking for is the first type or the second type, with your status and connections, can you find out these hidden information?"
