Zusammenfassung:	A lifelog data system using homomorphic encryption according to an embodiment of the present invention comprises: a hardware security module (HSM) device for generating and storing a first encryption key for homomorphic encryption and a second encryption key for general encryption, and managing access to the first encryption key and the second encryption key; a personal identification data storage device for storing first encryption data associated with the first encryption key and meta-information representing the characteristics of the first encryption data together; a measurement item data storage device for storing second encryption data associated with the second encryption key as a file name including a globally unique identifier (GUID); and a blockchain device for managing mapping information indicating association between the first encryption data and the second encryption data. Therefore, provided are a lifelog system using homomorphic encryption and an operation method therefor, wherein concerns about preserving the privacy of patients can be eliminated and regulations regarding personal information can be overcome. 본 발명의 일 실시예에 따른 동형 암호를 이용한 라이프로그 데이터 시스템은 동형 암호를 위한 제1 암호키 및 일반 암호를 위한 제2 암호키를 생성 및 저장하고, 제1 암호키 및 제2 암호키에 대한 액세스를 관리하는 하드웨어 보안 모듈(HSM) 장치; 제1 암호키와 연관된 제1 암호화 데이터와 제1 암호화 데이터의 특성을 나타내는 메타 정보를 함께 저장하는 개인식별 데이터 저장장치; 제2 암호키와 연관된 제2 암호화 데이터를 GUID(Globally Unique Identifier)를 포함하는 파일명으로 저장하는 측정항목 데이터 저장장치; 및 제1 암호화 데이터와 제2 암호화 데이터의 연관성을 지시하는 맵핑 정보를 관리하는 블록체인 장치를 포함한다.
