Mary Lin asked:
“What does one way mean?”
The old man explained:
“One trip means KTP, passport, driver’s license, even household registration booklets, marriage certificates and other KTP documents are all original.
and KTP numbers are also real, but if anyone in the system wants to I can’t find the information with a fuzzy query.”
“For example, if I want to check who is Charlie in the whole country,
the information will not appear in the results returned by the system.”
“Information about Wade’s people will not include him in the results,
even if we spit out hundreds of millions of men across the country, there wouldn’t be him in it ;”
“If you want to check the information, there are two Conditions, first of all,
You must know their name and accurate ID number, and only if these two pieces of information are absolutely correct,
You can find out the information;”search,
because like you, you really need to use this system to find someone in a large crowd,
You can’t know the ID number, if you know the ID number, then you have mastered it.”
“This way, you don’t have to use this system to spread the net.”
Maria Lin sighed:
“In this way, this encryption method is still very clever, and people who don’t know it well are in the system.”
“I can’t find him, and it’s impossible for people who know him to come to the department again.”
“Check the information in the system, even if someone who knows him checks it,
entered the name and ID number, the result is correct, and there is no hint. “
“Check the information in the system, even if someone who knows him checks it,
entered the name and ID number, the result is correct, and there is no hint. “
“Yes. “The old man nodded and said:
“Some people with very special identities will use this method to hide,
so that one can really hide in the city.”
“Everything is true, but everything makes everyone There is no way to verify his ulterior motives.”
Speaking, the old man said again:
“Such a person, using his own identity, not only doesn’t have to worry about being found out by others,
but also his life will not be affected in any way. “
Because apart from what I said earlier, the information can only be known from the name and KTP number.”
“All of his KTPs are actually one-way channels of investigation;”
“For example, if a policeman checks his KTP on the street, as long as the police use that tool to read his KTP,
all the information can be asked in the system, so the police don’t find anything wrong;
If he has the correct name and KTP, he can check-in smoothly with KTP;”
“If he wants to go abroad, then use his name and passport number to order tickets,
and then he can exit customs smoothly with his passport; “
“However, if anyone wants to check through the information registered on the plane,
impossible to know.”
“If you want to find someone named Charlie who has flown in China,
but you only know the Name, then the information will not be displayed. “
Maria Lin’s two willow-like eyebrows were slightly clustered in the middle, her expression dignified and worried.
After hesitating for a moment, he asked the old man:
“It doesn’t matter whether the person I’m looking for is the first type or the second type.
can you find out this hidden information? “
