블록체인 기반 의료정보시스템에서 프라이버시 보장을 위한 보안 기법에 관한 연구

Abstract

To provide data integrity and reliability, the blockchain technology is suitable for the medical information system. But the system uses sensitive and personal data, privacy issues still remain. Hence, the blockchain-based privacy-preserving medical information system has been studied actively. We introduce the studies and describe future research issues for the blockchain based medical information system.
