DATA QUERY AND CALCULATION METHOD AND SYSTEM, AND STORAGE MEDIUM

摘要

Disclosed are a data query method, a computer system and a storage medium. The method comprises: a second data query system sending at least one query service on the basis of a query demand of a target user (S110); a first data query system receiving the at least one query service sent by the second data query system and forwarding same to a corresponding third data query system (S210); the third data query system receiving the at least one query service (S310); obtaining, according to information to be queried, a query data set of a user group in which the target user is located (S320); acquiring a query result corresponding to the target user from the query data set according to a query request on which first-type encryption processing is carried out and giving feedback (S330); the first data query system merging, according to the query service, the query result, corresponding to the target user and the information to be queried, acquired from at least one third data query system (S220); the second data query system acquiring, according to each query service, the query result corresponding to the target user (S120); carrying out a consistency check on each acquired query result and check data provided by the target user (S130); and when consistency is met, carrying out, on the basis of each query result, evaluation calculation corresponding to the query demand (S140). In the method, by means of using an encrypted query result, the leakage of the query result can be effectively prevented, a data source can also be protected, and an anonymous query can be provided in the case of authorization.
