MediBloc, which operates the blockchain medical information platform’MediPath’, announced on the 18th that it will launch a distributed identification (DID)-based vaccine pass service in April.
Vaccine Pass is a service that allows you to check and manage the history of vaccinations registered with the Korea Centers for Disease Control and Prevention and linked medical institutions using DID technology. DID technology verifies the authenticity of an individual’s vaccination history. The details of the vaccination certificate signed with the DID given to the information providing institution, including the linked medical institution, are stored on the patient’s mobile. It explains that it can be shared externally only if the patient wants, so it can be used with confidence without fear of unauthorized use of data. Afterwards, other organizations or individuals who have shared the vaccination details can use the DID to determine whether the details are forged or altered.
MediBloc’s own DID used in the vaccine pass was officially registered with the international organization W3C. This can be found directly on the W3C site. MediBloc explained that the official registration of the W3C complies with international standards and is compatible with other DIDs.
“Existing paper certificates have a high risk of forgery and alteration and could only cover face-to-face situations,” said Ko Woo-gyun, co-representative of MediBloc. “It will be effective because it can be used safely.”
MediBloc is expected to secure completeness through tests for medical staff at corona19 confirmed patients treatment hospitals, senior general hospitals, and medical institutions at general hospital level who are the first candidates for vaccination. It is planned to be officially released by MediPass as early as April. Medipass, which provides a vaccine pass, can be downloaded from the Apple App Store or Google Android Market.
