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.
