BUSINESS DATA PROCESSING METHOD, VERIFICATION METHOD, APPARATUS AND SYSTEM

摘要

A business data processing method, verification method, apparatus and system are disclosed in the embodiments of the present invention. The method comprises: acquiring a to-be-processed service data, and generating a fingerprint data of the to-be-processed service data in a preset manner; writing the fingerprint data into a blockchain corresponding to the to-be-processed service data to generate a blockchain copy data of the to-be-processed service data in the blockchain, and the blockchain copy data stores the fingerprint data in the adjacent previous node blockchain copy data. Employing various embodiments of the present application, in the case of little influence on the original processing flow and performance, a copy of the original service data can be stored by means of writing the fingerprint data embedded in the original service data into blockchain, thereby fundamentally achieve verifying whether the service data is tampered with, ensuring the service data cannot be modified, and improving the reliability and credibility of the service data.
