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?"

Hearing Lin Wan'er's question, the old man pursed his lips and sighed: "Miss, there is actually a very troublesome underlying logic behind this matter."

Lin Wan'er said, "Say it."

The old man said: "Whether it is the first type or the second type, the number of people who are hidden is actually not small. Some special talents, military experts, intelligence personnel, and secret service personnel have their identities encrypted. Tens of thousands of people."

Speaking of this, the old man changed the subject and said again: "But the trouble is that although these two kinds of hidden people have a database, most of the people who can access this database do not have this database. highest authority."

"That is to say, if I used these two methods to hide the information of two people, then even if I have the authority to this database, I can only access the information of these two people, and I have no information about other people. Those who have the right to read, not only do not have the right to read, I don�t even know how many people are in it;�

"Conversely, even if you also have the relevant authority of this database, you can't find out who I am hiding in this database. The two of us are insulated from each other;"

"Moreover, there are multiple branches, each with different levels and authorities. For example, the intelligence department, its top leader, has the right to access the hidden information of all intelligence departments, but has no right to access the information of other departments. Condition."

Lin Wan'er thought for a while and asked, "There must be someone who has access to the entire database, right?"

The old man smiled awkwardly: "Miss, there are very few people with authority, and they can be counted on one hand, and it is absolutely impossible for these people to leak information to anyone who does not have authority, so I will take this road now. No way."

"I understand." Lin Wan'er nodded, knowing that it was already impossible to start from the access authority of the database.

So, after thinking for a long time, she suddenly remembered something and asked, "By the way, if a person's identity information is not concealed from birth, can his information before being concealed be found?" JrNovels.com
