A1

Provided are a data query method, apparatus, and system for a multi-party secure database. The method applied to a central node comprises: receiving a data query request from a data requesting party, the data query request relating to several items of target data stored by several data providing parties (21); determining whether the data query request meets the respective security requirements of the several items of target data (23); when the data query request meets the respective security requirements of the several items of target data, processing the several items of target data to acquire result data (25); and sending the result data to the data requesting party (27). On the basis of the security requirements of the target data stored by each data providing party, the central node restricts the query of the data requesting party for the target data, such that the data providing parties implement restricted external sharing of the target data by means of the central node, providing a secure data solution for sharing scenarios and facilitating security protection of some or all of the target data.
