관계형 및 NoSQL DBMS에서 관리되는 데이터세트에 대한 블록체인 기반 무결성 검증 방안 연구

Abstract

According to the E-Government Act enacted in 2002, as the government work environment shifted to electronic documents, 16,228 administrative information systems and 19,533 databases were installed to manage electronic documents. In 2020, public records management for administrative information datasets was promoted in earnest by amending the enforcement ordinance on public records management and enacting public standards for administrative information dataset records management standards. The records management system, which was limited to electronic documents, has now been encompassed to the dataset. Since each electronic document is stored in a file, datasets are managed in the currently running DBMS(RDB, NoSQL, etc.), unlike records management in units of files, it is difficult to introduce the existing method of verifying the integrity of each file to datasets. Therefore, in this study, we propose a method to verify the integrity of datasets managed in relational and NoSQL databases based on blockchain. By implementing a prototype, we proved that the proposed method can effectively verify the integrity of datasets in the DBMS. The research results of this paper are expected to provide a technological base to verify the integrity of the current records management field where large-capacity electronic records are produced in the future.
