Hearing Lin Wan'er's question, the old man pursed his lips and sighed: "Miss, in fact, 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, or the second type, the number of hidden people is actually not small.

Thousands of people. ""

Speaking of which, the old man turned around and said: "But, the trouble is troublesome, although these two hidden people have a database, most people who can contact this database do not have this database.

Most permissions. "

"In other words, if I used these two methods to hide the information of two people, then even if I have the permissions of this database, I can only read the information of my two people, other people's information, I have no information, I have nothing to do

I have no right to read the right to read, but I do n’t even know how many people in it here; ""

"On the other hand, even if you have the relevant permissions of this database, you can't find the people I hidden in this database. The two of us are insulating each other;"

"Moreover, there are multiple branches in it. Each person's level and authority are different. For example, the intelligence department, its highest person in charge, has the right to read all the information hidden information, but there is no right to read the other departments from other departments.

Condition."

Lin Wan'er thought about it and asked, "Someone must have the permissions to read the entire database?"

The old man smiled embarrassed: "Miss, there are very few people who have the authority, and one hand can be counted, and these people can never leak information to anyone without permissions. Therefore

No. "

"I understand." Lin Wan'er nodded and knew that it was impossible to read the authority from the database.

So, she thought about it for a long time, and suddenly remembered something, and asked, "Yes, if a person is not hidden from birth, he has not hidden the information before, can he find it?"

The old man replied: "If all the first information is hidden, it seems that this person has never appeared in the world, then the information he was born will be erased;"

"If it is the second type, it depends on how the person who hides his information will operate. Some people may be wiped out because of some purposes;

Then you won't erase the previous information, because this information must be made public, and the inquiries of someone who are in the heart. "

"For example, when a person graduated from college 22 years old, for some reason, he needed evaporation of others. Then his file information before the age of 22 will not be erased, and he will only add a missing population to his archives, or it has already already been added, or it has already already been.

The label of death, this information will not be encrypted, even if it is just an ordinary police officer with the lowest permissions, can easily find the archive information before his disappearance. "

Lin Wan'er's eyes lighted up and asked with a blut: "In those information you just gave me, do you include Ye Chen who has been missing and dead?"

The old man replied: "It contains the disappearance, but does not include the death that has been confirmed."

Lin Wan'er suddenly thought that she did see the information of a lot of children just now.

However, when I saw the photos of the children, I was skipped directly, and I didn't look at the specific information of these children.

However, this will ignore a situation, that is: if this child's photo is not the actual state of the child, but this child disappears when he was young, and his archive information stays in his young

When it was updated, this situation would be ignored just now.

So, she quickly said to the old man: "I look at the information of the missing person again. If I can't find it, you will help me retrieve the information of the relevant person who has died."

The old man nodded: "No problem!"

Looking at the computer again, returning the information back to the first person, and then starting one by one.

Soon, a black and white photo appeared in front of her eyes, causing her pupils to shrink.

The boy in this black and white photo looks like he is six or seven years old. The boy looks handsome, and the facial features and Shen Yun make Lin Wan'er feel that it is slightly familiar.

Later, she looked at the boy's information and muttered in her mouth: "Ye Chen, Yan Jing, Ye Changyi and An Chengyi ..."

"This Ye Chen, who studied at Yanjing Second Experimental Primary School 21 years ago, transferred to Jinling First Primary School twenty years ago, and then disappeared. The archive information has not been updated ..."

The old man heard her muttering and couldn't help but said: "Ye Changye, An Chengyi? This couple, more than 20 years ago, can be described as the wind in Yanjing!"

Lin Wan'er asked him: "Have you heard of it?"

"Not only I heard." The old man said seriously: "I have some friendship with the Ye family. The old house of the Ye family is not far from me. It can be arrived in half an hour. The Ye family is the top three families in Huaxia.

Ye Changye was the most outstanding back of the Ye family. His wife An Chengyi was almost the investor of Silicon Valley. By the way, An Chengqian's home behind him ranked second in the United States. "

"So!" Lin Wan'er nodded and sighed: "No wonder the name An Chengyi is so familiar, I seem to have read the biography of her characters."

Speaking, Lin Wan'er looked at Ye Chen's black and white crown photos before the first grade of elementary school. He said seriously: "I see this child, Ye Chen is a bit similar to Ye Chen I was looking for.

I guess the probability is him. "
