Abstract
The invention relates to the technical field of electric digital data processing, in particular to a data encryption method for realizing multi-party security sharing of financial data, which comprises the following steps of: acquiring financial data of different customers from each data provider, and respectively performing sensitivity analysis on the financial data to obtain data sensitivity corresponding to each financial data; determining the data feature importance degree of each piece of financial data according to the data sensitivity, layering the financial data according to the data feature importance degree to obtain a target layer corresponding to each piece of financial data, and processing the financial data by using a differential privacy algorithm according to the target layer to obtain a target layer corresponding to each piece of financial data. According to the method, the differential privacy result corresponding to each piece of financial data is obtained, and the encrypted data shared among the data providers is obtained according to the differential privacy result and the homomorphic encryption algorithm, so that the encryption is more targeted, and the calculation complexity can be reduced, the calculation efficiency can be improved, and the security can be improved.
