Business data processing method, verification method, device, and system

摘要

A business data processing method, verification method, apparatus, and system are disclosed in an embodiment of the present invention. The method is to acquire service data to be processed, generate fingerprint data of the service data to be processed by a preset method, and obtain blockchain copy data of the service data to be processed in the blockchain. Writing the fingerprint data to a block chain corresponding to the service data to be processed to generate, the block chain copy data stores the fingerprint data in the block chain copy data of an adjacent previous node. Using the various embodiments of the present application, a copy of the original service data is stored by writing fingerprint data embedded in the original service data to the blockchain, with little impact on the original process flow and performance. It is possible to verify whether the service data has been tampered with, to ensure that the service data cannot be modified, and the reliability and reliability of the service data. Achieve fundamental improvement in truthfulness.
