Hearing Lin Wan'er's question, the old man pursed his lips and sighed: "Miss, actually there is a very troublesome underlying logic behind this matter."
Lin Wan'er said: "You say."
The old man said: "Whether it is the first type or the second type, the number of people who are hidden is actually not that small. Some special talents, military experts, intelligence personnel, and special service personnel have their identities encrypted. How many people are there in total in the country?"
Thousands of people.”
At this point, the old man changed the topic and said: "But the trouble is, although these two types of hidden people have a database, most of the people who have access to this database do not have this database.
Highest authority."
"In other words, if I had used these two methods to hide the information of two people, then even if I had permission to this database, I could only access the information of these two people. I would not be able to access the information of other people.
Those who have the right to review, not only do not have the right to review, I don’t even know how many people are here;”
"On the other hand, even if you also have relevant permissions for this database, you can't find the people I hide in this database. The two of us are insulated from each other;"
"Moreover, there are multiple branches here, each with different levels and authority. For example, the intelligence department, its top leader has the right to access all the information hidden by the intelligence department, but does not have the right to access the information of other departments.
Condition."
Lin Wan'er thought for a while and asked: "There must be someone who has the authority to access the entire database, right?"
The old man smiled awkwardly: "Miss, there are very few people with authority, you can count them on one hand, and it is absolutely impossible for these people to leak information to anyone without authority, so this is the path I am taking now.
It doesn’t make sense.”
"I understand." Lin Wan'er nodded, knowing that it was impossible to start with database access permissions.
So, she thought for a long time, suddenly remembered something, and asked: "By the way, if a person's identity information has not been hidden since birth, can his previous information be traced?"
The old man replied: "If it is the first method where all information is hidden, making it seem like this person has never appeared in this world, then the information about his birth will also be erased;"
"If it's the second type, it depends on how the person hiding his information operates. Some people may erase it all for certain purposes; but some people, if they want to create the illusion that the person's whereabouts are unknown,
Then the previous information will not be erased, because this information must be made public to respond to inquiries from interested parties.”
"For example, if a person needs to disappear from the world for some reason when he is 22 years old after graduating from college, then his file information before the age of 22 will not be erased. Only a missing person will be added to his file, or it will be a missing person.
The information on the death tag will not be encrypted, and even an ordinary police officer with the lowest authority can easily find the file information before his disappearance in the population system."
Lin Wan'er's eyes lit up and she blurted out, "Does the information you just gave me include the missing and dead Ye Chen?"
The old man replied: "Including those who are missing, but not those who have been confirmed dead."
Lin Wan'er suddenly thought that she had indeed seen a lot of information about children just now.
However, when I saw pictures of children, I just skipped them without looking carefully at the specific information about these children.
However, this will ignore a situation, that is: if the photo of the child is not the actual state of the child now, but the child disappeared when he was young, and his file information still remains in his childhood.
, it was not updated again. In this case, I would have ignored it just now.
