Abstract
A data processing method based on secure multi-party computation, an electronic device and a storage medium are disclosed. The data processing method requires firstly obtaining original confidential data and shared key information from a data holding terminal; performing a first encrypting process to the original confidential data based on the shared key information to generate original encrypted data; and then sending the original encrypted data to a node server. Further, the node server obtains a plurality of pieces of the original encrypted data, and performs a service parsing process to generate encrypted result data, and sends the encrypted result data to a data reconstruction terminal. Furthermore, the data reconstruction terminal obtains the encrypted result data and the shared key information, and performs a reconstructing process to the encrypted result data according to the encrypted result data and the shared key information to obtain service result data.
