Data query system and method, storage medium and terminal

Abstract

The invention discloses a data query system and method, a storage medium and a terminal. The system comprises a demander terminal and a supplier terminal. The demander terminal sends a to-be-queried data table, wherein the to-be-queried data table comprises second marker information generated according to identifier information of to-be-queried data and an identifier code of the supplier terminalreceiving the to-be-queried data table, and the type of to-be-queried feature information. The supplier terminal processes the received to-be-queried data table and sends the processed data table, wherein the processed data table comprises the value of the to-be-queried feature information and the second marker information; and in response to operation of receiving the processed data table, the demander terminal performs secondary processing on the processed data table to obtain a data table subjected to secondary processing, wherein the data table subjected to the secondary processing comprises the value of the to-be-queried feature information and the identifier information of the to-be-queried data. Through the scheme provided by the invention, sensitive information can be effectively isolated during data query, so that the privacy of personal privacy information is guaranteed and the leakage risk is lowered.

Description

technical field [0001] The invention relates to the field of data query, in particular to a data query system and method, a storage medium, and a terminal.

Problems solved by technology

However, due to commercial interests and industry regulatory issues, these citizens’ personal privacy information is likely to be circulated to other channels and used by lawbreakers, which leads to financial institutions needing to collect more citizens’ personal privacy information from citizens as the basis for auditing , resulting in more private information of citizens being leaked during the data query phase

[0004] Repeatedly, a vicious circle is formed, and everyone's personal privacy information gradually spreads to the black / gray industry chain, which leads to serious problems of personal privacy information leakage, and also brings security risks to the society
