Block chain based business data tracing method, device and system and storage equipment

Abstract

An embodiment of the invention provides a block chain based business data tracing method, device and system and storage equipment. The method includes: receiving a tracing request which comprises a business data feature identifier; matching the business data feature identifier in a block chain of a local business node to acquire corresponding summary information, wherein the summary information refers to information generated by each business node on the basis of business data and / or aiming at operating information of the business data; extracting feature information corresponding to the business data feature identifier from the summary information so as to accurately learn where the business data comes from and goes to according to the feature information, so that management of a whole life cycle of the business data is facilitated.

Description

technical field [0001] The present invention relates to the technical field of business data processing, in particular to a blockchain-based business data traceability method, device, system and storage device. Background technique [0002] With the rapid development of global informatization work, information security has become a world-class focus, especially in the network environment, business data such as digital archive information will be in every stage of its formation, processing, transmission, storage, maintenance and provision of utilization. Facing security risks and being threatened by security. [0003] Currently, refer to figure 1 The schematic diagram of the unified ledger technology architecture of the prior art is shown. The unified ledger technology centrally stores business data from different application systems, and provides a unified query interface for traceability query, so that the same user can uniformly query all application systems. For busines...

Problems solved by technology

[0006] (1) Distributed storage of ledger data, with many computing nodes, if a node is compromised, it will lead to a large amount of leakage of file data of this node and other nodes

[0007] (2) Once the service node of the unified ledger center is compromised, it will cause the paralysis of the whole network ledger system

[0008] (3) The number and location of nodes are dynamically adjusted, and the security protection measures for single nodes must also be dynamically adjusted accordingly, resulting in a large workload for later operation and maintenance

[0009] The security of the existing unified ledger technology depends on the security of a single node, and its security is not high. Once one or some nodes are compromised, it is impossible to perform correct traceability queries on business data

[0010] In addition, the current business data management system lacks a unique identifier that cannot be tampered with and persists to trace the source of business data
