Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a data fusion method, devices, a data fusion system, and a storage medium. The method comprises: for fusion groups having a requirement, creating dedicated fusion services for the fusion groups in a trusted execution environment (300); acquiring a behavior control rule signed and issued by each participant in the fusion groups; and on this basis, in the trusted execution environment, responding, by using the fusion services and within the range of the behavior control rules, to a fusion calculation request sent out in the fusion groups (302). Accordingly, fusion calculation processes of different fusion groups can be separated from each other on the basis of different fusion services created for the different fusion groups; and the fusion services are completely run in a trusted execution environment, cannot be tampered with, and work according to behavior control rules by default, such that the problem of unauthorized leakage of data of participants during the fusion calculation processes can be completely eliminated, thereby ensuring the security and/or privacy of the data.
