Abstract

After the 4th industrial revolution, the healthcare industry is striving to find new business models through new technologies. Among them, blockchain technology is one of the technologies that have great interest in the healthcare industry. Most providers of personal health record systems have difficulty in securing marketability due to various problems. Therefore, they try to integrate blockchain technology to develop new systems and gain marketability. However, blockchain has limitations in solving the problems of the personal health record system. In this study, we have designed a personalized health data management framework that enables information subjects to acquire full ownership rights of individual's health data, based on distributed ledger technology. For the framework design, we refer to the structure of R3 Corda. It was designed with a different network structure than the existing blockchain systems so that the node can be operated on the personal user's mobile device. This allows information subjects to directly store and manage their own data and share data with authorized network members. Through the proposed system, the information utilization of the healthcare industry can be improved and the public health promotion and medical technology development can be realized.

4차 산업 혁명이 시작되고 헬스케어 분야 역시 신기술을 접목한 새로운 비즈니스 모델을 찾기 위해 노력하고 있다. 그중 블록체인 기술은 의료 분야에서 큰 관심을 갖는 기술 중 하나이다. 여러 가지 문제들로 인하여 시장성 확보에 어려움을 겪고 있는 개인 건강 기록 시스템 분야 역시 블록체인 기술의 접목을 통해 시스템의 발전과 시장성 확보를 위한 노력을 기울이고 있다. 하지만 블록체인은 개인 건강 기록 시스템의 문제를 해결하기에는 한계가 있다. 이에 본 연구에서는 블록체인의 상위 개념인 분산 원장 기술을 기반으로 정보 주체가 개인 건강 데이터에 대한 온전한 소유권을 확보할 수 있는 개인 주도적 건강 데이터 관리 프레임워크를 설계하였다. 프레임워크의 설계를 위해 컨소시엄 블록체인 중 하나인 R3 Corda의 구조를 참고하였으며, 개인 사용자의 모바일 장치에 노드를 운용할 수 있도록 기존 블록체인과 다른 네트워크 구조를 설계하였다. 이를 통해 정보주체가 직접 자신의 정보를 저장 및 관리하고 허가된 네트워크 구성원들에게 정보를 공유할 수 있도록 하였다. 제안된 시스템을 통해 의료 산업의 정보 활용도를 향상시키고 국민 건강 증진과 의료 기술의 발전을 이룰 수 있을 것이다.
