摘要

A learner history information management and evaluation subject verification system using blockchain is provided. The learner history information management and evaluation subject verification system using the block chain is the first node where students, trainees or parents are the users as the block chain participation node of the learner account, and the teacher, instructor or The second node where the learning code is the subject of use, the third node where a school, academy or institution is the subject of use as a blockchain participation node of the Learning Center account, and the blockchain participation node of the public account, where researchers or recruiting companies are the subjects of use A fourth node, a management server that performs identity authentication and authorization for the first to fourth nodes, and a verification server that performs an operation of verifying a qualification of a user of the second node, wherein the The second node and the management server each register DID information in the block chain, and the management server receives an electronic verification certificate that can verify the identity, qualification, history and career of the user of the second node from the verification server. Delivered to a second node, but the electronic verification document includes DID information of the management server and DID information of the second node, the second node performs a digital signature procedure on the electronic verification document, and the first to second nodes 4 nodes are configured to record learner history information on the block chain or read the learner history information recorded on the block chain, and the learner history information is big data concept information for building a personal portfolio, public records , records of village study site activity, online learning activity record, health record, lifestyle record, and study code submission record.
