Block chain-based service information collaboration method, service system and alliance chain

Abstract

The invention discloses a block chain-based service information collaboration method, a service system and an alliance chain. The method comprises the following steps that: a query request submitted by a user is received, and stored query information associated with the query request is extracted; a shared data form is produced; the shared data form is signed by using a stored private key, the shared data form is diffused into an alliance chain, so that a node receiving the shared data form verifies the signature of the shared data form by using a public key, and adds query information associated with the query request and stored in the node into the shared data form; after all service systems in the alliance chain add the query information into the shared data form, the service systems participate in the consensus authentication of the query information in the shared data form; after the consensus authentication is completed, a complete data form subjected to the consensus authentication is obtained; and query information in the complete data form is fed back to the user. With the method of the invention adopted, information resource sharing and data integration between service departments can be realized, and the security of the service departments is improved.

Description

technical field [0001] This application relates to the technical field of blockchain, and in particular to a blockchain-based business information collaboration method, business system and alliance chain. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] With the rise of the Internet, the traditional business system is increasingly unable to meet the requirements of the people. The current business system adopts a centralized approach, which mainly has the following problems: [0004] 1. The databases of various business departments are independent of each other, information resources cannot be shared, and there is a lack of integration interfaces, making information integration difficult and complete data cannot be provided externally. [0005] 2. The data of each business d...

AI Technical Summary

Problems solved by technology

[0004] 1. The databases of various business departments are independent of each other, information resources cannot be shared, and there is a lack of integration interfaces, making information integration difficult and complete data cannot be provided externally

[0005] 2. The data of each business department is stored separately, and the cost of hardware and software remains high

[0006] 3. The safety factor of the business system is average, it is easy to be attacked and tampered by hackers, and there are hidden dangers in network security

[0007] 4. Data exists between various business departments, and the departments do not trust each other, and the data types of different business departments are inconsistent, resulting in difficult data exchange and sharing. It is difficult to realize real-time sharing and synchronization of user authorization information, and it is easy to form data islands
