Abstract

Recently, the medical service sector is changing electronic health records from local environments to cloud environments for service quality and time reduction. However, cloud-based EHR software poses some risks in the medical field, so additional measures are needed to cope with these threats. In this paper, we propose a blockchain-based electronic health record management model in a distributed cloud environment. The proposed model improves the quality of medical services by grouping electronic health records into blockchains as a way to safely store and process patient electronic health record information in a distributed cloud environment. In addition, the proposed model guarantees the integrity of electronic health record information by restoring the damaged electronic health record information by changing the location of the URL 'path' stored in the block so that different medical staff can determine electronic health record information as a root hash in a cloud environment so that health records can be shared.

최근 의료 서비스 분야는 서비스 품질 및 시간 단축을 위해서 전자 건강 기록을 로컬 환경에서 클라우드 환경으로 변화하고 있다. 그러나, 의료 현장에서 클라우드 기반 EHR 소프트웨어는 일부 위험이 내포되고 있어 이러한 위협들을 대응할 수 있는 추가 방안이 필요하다. 본 논문에서는 분산형 클라우드 환경에서 블록체인 기반의 전자 건강 기록 관리 모델을 제안한다. 제안 모델은 분산 클라우드 환경에서 환자의 전자 건강 기록 정보를 안전하게 보관·처리하기 위한 방법으로 전자 건강 기록들을 블록체인으로 묶어 의료 서비스 품질을 높이고 있다. 또한, 제안 모델은 서로 다른 의료진이 건강 기록들을 공유할 수 있도록 클라우드 환경에서 전자 건강 기록 정보를 루트 해시로 판별할 수 있도록 블록에 저장된 URL '경로'의 위치를 변경하여 손상된 전자 건강 기록 정보를 복구하여 전자 건강 기록 정보의 무결성을 보장한다.
