AI Technical Summary

Technical Problem

The centralized databases of traditional education and training institutions are prone to data tampering, the cross-institutional recognition of scores is inefficient, and anti-cheating measures are limited to offline and cannot cover online examination scenarios.

Method used

By employing consortium blockchain networks, IPFS distributed storage, and smart contract technology, a teacher qualification certification and grade storage system is constructed. The system ensures data immutability through hash value on-chaining and IPFS storage, and adopts a dynamic trusted score model and anti-cheating verification module. Combined with the Polkadot cross-chain protocol, it achieves cross-institutional mutual recognition.

Benefits of technology

The risk of data tampering is reduced by 99.9%, the efficiency of cross-institutional mutual recognition is improved to within 2 hours, the accuracy rate of anti-fraud reaches 98.5%, and the cost of manual review is reduced by 70%.

Abstract

The invention discloses a teaching and training talent qualification authentication and question brushing result evidence storage system based on a block chain, the core of the system is an alliance chain network containing education supervision nodes, and the efficiency is improved by adopting an improved practical Byzantine fault-tolerant consensus algorithm and a fragmentation technology. IPFS storage and on-chain evidence storage of qualification data are realized through a teacher qualification authentication module, and the authenticity of the data is guaranteed in combination with manual verification; the student score evidence storage module collects answering behavior data in real time, verifiable digital certificates are generated after abnormal filtering and manual rechecking, and credibility is enhanced through a Merkel tree root anchored bitcoin network. A dynamic credible score calculation module, a multi-level anti-cheating verification module and a Polkadot cross-chain interoperation module are matched, credible scoring, cheating recognition and cross-domain credit mutual recognition are achieved, and the meta universe teaching evidence storage function can be expanded. According to the system, through cooperation of technologies and manpower, the problems of teaching and training qualification counterfeiting, untrusted scores, difficulty in cross-domain mutual recognition and the like are solved, the education supervision efficiency is enhanced, and the system adapts to multiple teaching scenes.
