Chapter 2501: Encryption Logic

Ten minutes later.

The old man knocked on the door, and after getting Lin Wan'er's permission, he pushed the door open and walked in somewhat slowly.

And in his hand, he was holding a laptop.

He placed the computer in front of Lin Wan'er and said: "Miss, the information you asked me to check has been found. There are a total of 2,128 males in the country with the surname Ye and the name Chen (early morning), and 879 are under thirty;"

"There are a total of 540 males in the country with the surname Ye and the name Chen (stars), and 213 are under thirty;"

"There are only 20 males in the country with the surname Ye and the name Chen (dust), and only 7 are under thirty."

"Besides that, I have also retrieved the information of all males under thirty with the surname Ye and the name pronounced as 'chén' using pinyin, a total of 172 people;"

After saying this, he added: "All the information of these Ye Chen is here, please take a look."

"Good." Lin Wan'er nodded, placed her fingers on the arrow keys, and quickly browsed through the relevant information of each Ye Chen.

For the past few days, she had been repeatedly watching the surveillance footage and remembered Ye Chen's appearance clearly. So, the main comparison method now was to verify whether the information she saw and the Ye Chen she saw were the same person through the ID photos.

But strangely, after browsing through all the information, she didn't find the Ye Chen who saved her that night.

Lin Wan'er frowned and couldn't help asking the old man: "Is all the information of Ye Chen here?"

"Yes." The old man nodded: "Everything that can be found is here."

Lin Wan'er thought to herself: "Could it be that he lied to me at that time?"

Thinking of this, she couldn't help but shake her head: "Shouldn't be... he definitely had full confidence in being able to erase my memory at that time. In that situation, he didn't need to lie at all... And since he dared to take action against the Poqing Society, it's impossible that he wouldn't dare to reveal his real name to me in that situation..."

The old man saw Lin Wan'er frowning and silent, and couldn't help asking: "Miss, is there any problem? If you have any other clues, you can also tell me. One more clue, one more chance."

Lin Wan'er shook her head somewhat dejectedly and muttered: "There are no other clues, I only know his name is Ye Chen."

The old man smacked his lips: "All the people named Ye Chen are here. If he didn't lie, could he be an overseas Chinese? Although he is named Ye Chen and is also Chinese, his nationality is in another country?"

Lin Wan'er said: "He said he is Chinese, but it doesn't rule out what you said. After all, many overseas Chinese also have a strong sense of national identity and will say they are Chinese when they are outside. But if that's the case, there are more than two hundred countries in the world, and I can only look for a needle in a haystack..."

Speaking of this, Lin Wan'er raised her head somewhat unwillingly and asked the old man: "Is there a possibility that his identity has been encrypted in the system?"

"Encrypted?" The old man frowned and thought for a while, and said: "There are indeed cases of encryption. The information of people with special identities will be encrypted. However, to ensure that this encrypted information is not found, the system itself cannot directly retrieve the 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 the information is stored in another mutually isolated system, which means it has no connection with the network. That is to say, his real information only exists in the latter system, and no one outside can find any clues;"

As he said this, the old man added: "The other one is more complicated. This person has a set of real identity information himself, but this set of information is encrypted in the system, and to some extent becomes a one-way identity."

Lin Wan'er pursued: "What does one-way mean?"

The old man explained: "One-way means that his ID card, passport, driver's license, and even household registration book, marriage certificate, and other identity documents are all real, and the ID number is also real. But anyone in the system who wants to query his information vaguely will not 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. If I want to query the information of all people with the surname Ye in the country, the results will not have him. Even if we retrieve the information of hundreds of millions of males in the country, he will not be here;"

"If you want to query 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 his information be found;"

"In this way, it basically eliminates others' wide-net searching, because in a situation like yours where you really need to use this system to find someone in the vast sea of people, you can't know his ID number. If you already know his ID number, it means 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 well can't find him in the system, and people who know him well can't come to the system to check his information. Even if people who know him come to check, the result is real, and they can't find any clues."

"Yes." The old man nodded: "Some people with very, very special identities will use such methods to hide themselves, which can make a person truly hide in the city. Everything is real, but everything makes people with ulterior motives unable to verify."

As he said this, the old man added: "Such people, using their own identity, not only don't have to worry about being found by others, but their lives will not be affected at all;"

"Because besides what I just said, you must rely on the name plus ID number to find his information, all his documents are actually one-way query channels;"

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

"If he wants to take a plane, as long as he uses the correct name and ID card when buying a ticket, he can handle boarding with his ID card;"

"If he wants to go abroad, then use his name and passport number to book a ticket, and he can pass customs smoothly with his passport;"

"However, if anyone wants to check him through the information registered on the plane, it is impossible to find him at all. If you want to search if there is anyone named Ye Chen who has taken a plane in the country, but you only know his name, his information will not be displayed."

Lin Wan'er's two willow-like eyebrows gathered toward the middle, her expression solemn and worried.

After hesitating for a moment, she asked the old man: "Regardless of whether the person I'm looking for is the first type or the second type, with your status and connections, can you find these hidden information?" ===== CHAPTER 2502 =====
