基于区块链技术的学历学位证书认证设计

Academic degree certification design based on blockchain

国内目前学历学位认证存在流程复杂、耗费时间长、认证收费高等问题,难以满足毕业生和用人单位快速、公正、准确地核实信息的需求,无法实现创新应用.区块链技术具有去中心化、防篡改、可追溯、信息更改留痕等特点,能够有效解决目前国内学历学位认证存在的问题.在分析国外已有基于区块链技术发放教育文凭的项目后,文章提出一种基于联盟链(Hyperledger Fabric)的学历学位证书认证平台,进行了架构设计,包含业务系统层、区块层、服务层、应用层.平台节点分为教育管理部门、可信高校、学生和用人单位四类,并描述了注册数字身份、颁发数字学历学位证书、验证学历学位证书三大功能流程.平台技术采用基于授权的共识机制提高性能;仅存储数字文凭的哈希值,有效保护了个人隐私.本研究尝试从学历学位认证模式和技术上进行创新.

The domestic academic degree certification is inefficent in complicated process,long time and high certification fees,which makes it difficult to satisfy the needs of graduates and employers for quick,fair and accurate verification of information.It is impossible to achieve innovative application.Blockchain technology is characterized by decentralization,tamper resistance,traceability,and information change,which can effectively solve the problems existing in current domestic academic degree certification.After analyzing the foreign projects of issuing education diplomas in blockchain technology,this paper proposes an academic degree certificate platform based on the alliance chain Hyperledger Fabric,and carries out the architecture design,including the business system layer,block layer,service layer and application layer.The platform nodes are divided into four categories:education management department,trusted colleges,students and employers.It also describes the three functional processes of digital identity register,digital academic degree certificates issuing,and academic degree certificates verification.Platform technology uses an authorization-based consensus mechanism to improve performance and stores only the hash of the digital diploma,which can effectively protect personal privacy.This research attempts to innovate in the academic degree certification model and technology.
