Abstract

In recent years, various educational institutions have used online certificate services to verify academic achievement related to graduation and grades. However, the certificate of the existing system has limitations in verifying and tracking whether it is true or not and detailed academic background. In this regard, cases of forgery/falsification of online/offline certificates continue to occur. This study proposes a blockchain-based verification method that is safe from forgery and alteration, focusing on university institutions. Necessary information such as detailed class categories for each department, attendance, and detailed grades was collected/analyzed to create a linkage relationship through blockchain. In addition, the system/network environment required for blockchain sharing was considered, and it was implemented as an extension module in the form of an independent web application. As a result of the block chain verification, it was proved that the safe trust verification of educational information and the relationship between detailed information can be traced. This study aims to contribute to the improvement of academic credential verification services and information security for Korean educational institutions in the future.

최근 다양한 교육기관에서 졸업 및 성적에 관련된 학력 검증에 온라인 증명서 서비스의 활용도가 높다. 그러나, 기존 시스템의 증명서는 사실 여부와 세부 학력에 대한 검증과 추적에 한계가 있다. 관련하여 온라인/오프라인 증명서의 위조/변조 사건이 지속하여 발생하고 있다. 본 연구는 대학 기관을 중심으로 위변조에 안전한 블록체인 기반 검증 시스템을 제안한다. 학과 별 세부 수업 카테고리와 출석 및 세부 성적 등 필요한 정보를 수집/분석하여 연계 관계를 블록체인으로 생성했다. 이외 블록체인 공유에 필요한 시스템/네트워크 환경을 고려하였고, 독립적인 웹 애플리케이션 형태의 확장 모듈로 구현했다. 블록체인 검증 결과, 학력 정보의 안전한 신뢰 검증과 세부 정보들의 관계를 추적할 수 있음을 증명하였다. 본 연구는 향후 국내 교육기관 학력 검증 서비스 및 정보 보안 개선에 이바지하고자 한다.
