Abstract
A cross-domain sharing method and apparatus for zero-trust sensitive big data based on privacy computation is provided, so that a sensitive data provider can safely and fully import data into a database of a computing environment of a data user in a cross-domain manner for secondary use, and ensure that no malicious party can steal original sensitive data. The data user can develop and deploy an application as usual and faces no limitation on a deployment environment. With a zero-trust sharing environment, the sensitive data can be fully provided for a user area while the data provider only needs to examine the application of the user and approve the application to use the corresponding sensitive data if the application does not have a malicious leakage behavior. Further, the data provider can terminate data use by the application at any time by disabling an account.
