System and method for calling and storing service by using block chain

Abstract

The invention discloses a system and a method for calling and storing service by using a block chain, and belongs to the technical field of government affair data sharing. The system for performing service calling and evidence storage by using the block chain comprises a commitment department node, a service bus party node, a plurality of service provider nodes, a supervision department node, a service calling account book and an intelligent contract, and the commitment department node is responsible for constructing the service calling and evidence storage chain and formulating the intelligent contract with the privacy authority. The service bus party node and the plurality of service provider nodes form a service calling evidence storage chain sharing network. And the supervision department node carries out query supervision on the content on the storage chain according to the authorization permission. The system for carrying out service calling and evidence storage by using the block chain realizes permanent, safe and consensus credible collection and sharing of the credible evidence, so that traceability, cheating prevention and non-repudiation of service calling are ensured, and the system has very good popularization and application values.

Description

Technical field [0001] The invention relates to the technical field of government affairs data sharing, and specifically provides a system and method for using a block chain to perform service invocation storage certificates. Background technique [0002] Under the development trend of "Internet +", national and regional governments have carried out the construction of government affairs big data management system, and established government data sharing and exchange standards and government data sharing and exchange systems to break information islands, eliminate data and information chimneys of various departments, and open up Internal sharing channels meet the needs of information interconnection and sharing and exchange between relevant business departments of various departments, and provide strong guarantee for cross-departmental services of various business units. The service mode is a typical way of sharing government affairs data. After service registration and access t...

AI Technical Summary

Problems solved by technology

At present, the industry basically uses a single dependent log table or log file to persist service call instances and running process logs. Only by ensuring the security and reliability of the storage system can the service call records be credible and safe, otherwise these records are easily stolen. Tampering, cannot guarantee the safety and credibility of follow-up audit or tracking verification

In addition, the operation process log can be recorded by participants of different roles, such as the bus party or the service provider. These still have the problem of difficult data collection, and there are certain limitations to a certain extent, which need further improvement
