The invention discloses a data
backtracking method based on FATE privacy calculation, which comprises the following steps: S1, FATE service installation and unilateral test completion; s2, FATE
interconnection is carried out, and bilateral testing is completed; s3, accessing a user FATE through an independently developed FATE federation service; s4, accessing the FATE federated service to an FATE federated
algorithm; s5, the FATE federated service is accessed to the FATE task; s6, the model providing side customizes an
encryption algorithm, and provides a mapping API or an offline file; s7, the model providing side extracts the receipts and encrypts the receipts through a user-defined
encryption algorithm; s8, the model providing side initiates an FATE uploading task for the encrypted data through the federal service platform, uploads the data to an FATE
server and notifies the
data acquisition side; s9, the
data acquisition side selects an FATE algorithm, and initiates an FATE federated modeling task through the federated service platform; s10, the
data acquisition side initiates an FATE downloading task through the federated service platform after the federated modeling task is completed; and S11, after the data downloading task is completed, the data acquisition side processes the data through a customized decryption algorithm and an offline file and then stores the data. According to the method, the problems of data flow,
privacy protection and cross-platform compatibility are effectively solved; meanwhile, convenient operation is provided, and the risk of data leakage is reduced.
