Research And Design Of Continuing Education Management System Based On Consortium Chain And IPFS

With the rapid development of China’s digital economy,digitalization has penetrated all industries,constantly improving production efficiency.Digitalization is also widely used in traditional government affairs.Integrating traditional government operations into online operations has greatly improved the utilization of government resources and efficiency.However,in current government systems,such as the continuing education management system,there are often cases where business audit materials are incomplete under non-direct organizations,requiring the resubmission of business applications.At the same time,because data audit information and privacy audit materials are stored in third-party databases,it is easy to cause unclear audit responsibility chains due to data tampering.This thesis proposes and designs a continuing education management system based on a consortium chain as the underlying network architecture to solve the problem of audit data tampering and the security storage of privacy audit materials.This thesis mainly conducts research and innovation in the following aspects:1.In response to the message transmission security issues in the traditional Kafka consensus mode,a data index separation storage model based on TLS/SSL improved Kafka consensus mode is proposed.This model borrows from the idea of non-clustered indexes,combines the consortium chain with the interstellar file system,and separates the stored index from the relevant data in the consortium chain,avoiding the problem of excessive storage load caused by storing a large amount of business data in the block network.Network communication will also be more convenient.This model can perform secure message transmission under the premise of high performance.2.By combining traditional government systems with blockchain,data security that traditional government systems do not possess is solved.Inter-network communication uses smart contracts to execute proxy re-encryption processes,enabling secure ciphertext conversion of private audit materials and achieving secure file sharing,fundamentally solving the privacy leakage problem that centralized applications encounter.This thesis will conduct module testing after system design and implementation and test network performance using the testing tools provided by the blockchain official,analyzing the test results to verify network performance.
