After the COVID-19 outbreak in 2019, the spread of COVID-19 has not been easily caught despite preventive measures in each country. The spread of COVID-19 has hit the world, especially in the economic and tourism sectors. Countries around the world are easing restrictions on the movement of vaccinated people in preparation for the post-corona era. Under the name of "Vaccine Passport," "Vaccination Certificate," and "Digital Health Pass," vaccination measures are being implemented to allow vaccination recipients to use multi-use facilities. However, there is no international agreement on the movement of countries, and each country has its own immigration policy. In order to return to pre-corona daily life, global agreements must be reached from the movement of vaccinated people between countries, and standards and implementation methods must be determined. This study focuses on the implementation and utilization of vaccination certificates suitable for the COVID-19 era. We will look at the spread of COVID-19 and its international response policies. In the case of COVID-19, we will investigate why vaccination certificate installation should be standardized and how far the current standardization has been discussed, and discuss the characteristics of vaccination certificate installation and considerations. In order for the immunization certificate discussed in the previous chapter to be recognized internationally, institutional and technical considerations are identified and security factors that may occur in each implementation are also presented. Finally, the international recognition case of vaccination certificate is discussed, and the method of installation and utilization of vaccination certificate is proposed. This paper can be used as a policy because of its timeliness in studying the standards of vaccination certificates and considerations for international recognition to restore movement between countries in the spread of COVID-19. In addition, if other infectious diseases occur in the future or similar cases where movement between countries is restricted, it can be used as a reference to support the movement of verified people.

최근 COVID-19 팬데믹으로 인하여 많은 국가에서 감염병 예방 디지털 증명서를 위한 시스템을 도입하여 활용하고 있지만, 이에 대한 국제표준이 없어 국가 간 호환성 있는 증명서 사용의 어려움이 있다. 이에 본 논문에서는 기존 QR 코드 방식의 증명서 제출과 무선 근거리 통신 방식의 증명서 제출 방식을 비교하고 보다 개선된 무선 근거리 통신 방식의 디지털 증명서 시스템을 제안한다. 제안 시스템은 분산ID 기반의 증명서 검증 정보를 블록체인에 저장하여 국가별로 상이한 증명서의 상호 운용 체계를 구축하는 감염병 예방 디지털 증명서 시스템이다. 블록체인 기반의 신뢰앵커는 증명서 위·변조 문제를 해결하고 증명서 발행자와 제출자의 신원을 보증하여 보안성을 향상 시킬 것이다. 아울러 제안 시스템은 한 번의 증명서 제출로 다수 증명서(백신 접종증명서, 회복증명서, 검사 증명서, 신분증 등)를 일괄 검증토록 하여 이용자 편의성을 제고할 수 있을 것으로 기대한다.
