As the COVID-19 vaccination begins, it is necessary to safely store and manage the vaccination history for vaccinated people, as well as provide only the minimal information for the requested purpose, not in the form of all or nothing, to the institution requesting vaccination personal information. This paper proposes a scheme to safely store and manage the people's vaccination records in a non-forgeable blockchain, and to ensure that users provide only the minimal information necessary to the verifier from their vaccination personal information. A user authorizes the verifier to access the information he has consented with by entering the fingerprint on his smartphone, and in this process, no personal information or secrets can be exposed to an attacker. In addition, it is guaranteed that it is neither possible to impersonate the user nor to steal user personal information even in the case of theft or loss of the smartphone, or leakage of information from the vaccination history management institution. Using the scheme, users have no fear on external exposure of personal information and follow-up damage due to excessive information provision by giving out only the minimal information suited to the verifier.

최근 COVID-19의 백신이 개발되어 접종을 시작했다. 정부는 집단면역 생성을 위해 접종 목표치를 설정하고, 민관합동신속대응팀을 설립하는 등의 조치를 취하고 있다. 하지만 COVID-19의 백신이 다른 백신에 비해 개발 기간이 훨씬 짧을뿐더러, 효과가 입증되지 않아 신뢰를 얻지 못하고 있다. 블록체인은 거래 당사자 간의 거래정보를 네트워크에 참여하는 모든 구성원들이 공동으로 기록, 검증, 저장하는 분산장부 기술로 공인된 제3자 없이도 무결성 및 신뢰성을 확보할 수 있다. 이에 본 논문에서는 COVID-19 백신의 신뢰도를 제고하기 위해 블록체인을 기반으로 한 백신 접종 이력 관리 시스템을 설계하고, 향후 QR코드 등의 방식과 연동하여 백신 여권 등으로의 확장 가능성을 제시한다.

Purpose : This study aims to investigate preexposure prophylaxis and postexposure prophylaxis of rabies that the National Medical Center (NMC) handled and to check whether appropriate measures were performed according to the recent domestic and overseas guidelines after animal bites. Methods : This study surveyed 41 people who were 18 years or under and received preexposure and postexposure prophylaxis of rabies at the NMC from November 2006 to December 2011. Their medical records were reviewed for their age, gender, the reason for preexposure prophylaxis, the body sites of animal bite, the kind of the animal that bit children, the region where the biting occurred and rabies vaccination and inoculation of immunoglobulin. Results : Eleven children took rabies vaccination for preexposure prophylaxis and 30 children received post exposure prophylaxis of rabies. Of patients who were bitten by unvaccinated animals including wild animals or by animals which were not certain to be vaccinated, 50% (13 of 26 children) received postexposure prophylaxis, while 75% (3 of 4 children) of patients who were bitten by vaccinated animals received postexposure prophylaxis of rabies. Ten of 30 bitten patients knew whether or not the biting animals had received rabies vaccination. Of them, four people (40%) were bitten by animals which had received rabies vaccination. Conclusion : To prevent the occurrence of rabies, people and health care providers need to correctly understand latest guideline for rabies preexposure and postexposure prophylaxis and the information for bitten patient, biting animal and area at bitten by animal should be accurately recorded.
