Abstract

The invention provides a data query method and related equipment, and relates to the field of data security, the method comprises the following steps: executing grouping operation on data fields in a database server to obtain a plurality of grouped fields; issuing a plurality of grouping fields; receiving a query request of a data query end, wherein the query request comprises a grouping query condition, and the grouping query condition is determined by the data query end according to a corresponding relation between a target query condition and a published grouping field; determining an initial query result corresponding to the grouping query condition in a data field in a database server; and sending the first information to a data query end through an oblivious transmission protocol, wherein the first information is used for enabling the data query end to obtain a target query result from the initial query result, and wherein the target query result corresponds to the target query condition. Through the data query method and the related equipment provided by the invention, the safety performance of the data query process can be improved, and the leakage risk of user query data is reduced.

Description

technical field [0001] The invention relates to the field of data security, in particular to a data query method and related equipment. Background technique [0002] At present, with the continuous popularization and deepening of information technology applications, various information systems store and accumulate rich data, such as patient diagnosis data sets established by medical institutions, customer online transaction data sets collected by e-commerce companies, etc. Analyzing these data sets can enable people to gain more knowledge about the real world. For data research, information consulting, and government decision-making, data is a very important basic resource, which greatly promotes the demand for data query. However, the data query process may expose the user's query privacy. It can be seen that the security performance of the current data query process is relatively poor.
