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

Embodiment 1

[0046] refer to figure 2 , shows a flow chart of the steps of Embodiment 1 of a blockchain-based business data traceability method according to an embodiment of the present invention, and the method may include the following steps:

[0047] Step 101, receiving a traceability request, the traceability request including the characteristic identification of business data;

[0048] Step 102, match the feature identifier of the service data in the blockchain of the local service node, and obtain the corresponding summary information, wherein the summary information is the operation information based on the service data and / or for the service data of each service node generated information;

[0049] Step 103, extract feature information corresponding to the service data feature identifier from the summary information.

[0050] In the embodiment of the present invention, a block chain storing business data summary information is established, and the high security and tamper-resist...

Embodiment 2

[0052] refer to image 3 , shows a flow chart of steps in Embodiment 2 of a blockchain-based business data traceability method according to an embodiment of the present invention. Specifically, the blockchain can be a distributed shared database, and the blockchain is distributed in multiple On business nodes, blockchain technology refers to the technology of collectively maintaining a reliable database in a decentralized manner. This technology mainly associates blocks through cryptographic methods. Each data block contains all the data information of the system within a certain period of time, and generates a digital signature to verify the validity of the information and links to the next data block to form a main chain. , thus forming a blockchain, and the blockchains recognized by each business node sharing the blockchain are completely consistent.

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...
