Abstract

The invention provides a data joint query method, device and equipment and a computer readable storage medium. The method relates to a database technology and a block chain technology, and comprises the following steps: carrying out analysis and arithmetic unit division on a received joint query statement to obtain at least one operator containing a joint query operator; the joint query statement is used for synchronously initiating data joint query to the first equipment and the second equipment; converting the joint query operator into a first joint security operator based on a preset security protocol; synchronously executing the first joint security operator and a second joint security operator on the second equipment, and performing data interaction and joint calculation on first to-be-exchanged data of the first equipment and second to-be-exchanged data of the second equipment in a ciphertext form to obtain a joint data table; and processing at least one operator based on the joint data table to realize data joint query. By means of the method and device, the safety of data joint query can be improved.

Description

technical field [0001] The present application relates to database technology and blockchain technology, and in particular to a data joint query method, device, equipment, and computer-readable storage medium. Background technique [0002] At present, the data joint analysis scenario often involves the operation of intersecting two or more tables across data sources. When related technologies perform intersection processing of two or more tables across data sources, cross-source data exchange is mainly performed on the basis of mutual authorization, and intersection calculation is performed based on the exchanged data to obtain intersection data for data joint analysis content. The data joint query method in the related art has the risk of data being stolen by the other party participating in the exchange or intercepted by a third party, thereby reducing the security of data joint analysis. Contents of the invention [0003] Embodiments of the present application provide...
