METHOD AND APPARATUS FOR PROCESSING PRIVACY DATA OF BLOCK CHAIN DEVICE STORAGE MEDIUM

摘要

An embodiment of the present application discloses a privacy data processing method, equipment, device, and storage medium of the block chain, and relates to the technical field of the block chain. When executed by a blockchain node, as a concrete realization means, obtaining a data computation transaction request initiated by a data user based on a privacy smart contract - Invoking data in a data computation transaction request is blinded by the data user data is data that has been processed - with, by a data computation transaction request, obtaining isomorphic encrypted source data; and calling a privacy smart contract by a computation task in the data computation transaction request and performing calculations on the calling data and the source data. Execute to obtain a calculation result, and uplink the data calculation transaction request and calculation result, and feed back to the data user of the data calculation transaction request, so that the data user performs isomorphic decoding and blind removal processing on the calculation resu and obtaining a plaintext calculation result. Accordingly, the privacy data processing means of the blockchain are optimized.
