COOV for Android

COOV is the world’s first blockchain-based COVID-19 vaccination digital authentication application developed by the Korea Centers for Disease Control and Prevention and Blockchain Labs.

Through the use of blockchain technology, the falsification of digital certificates becomes impossible, and when the certificates are authenticated, there are no records left on any server, so sensitive personal information can be completely protected.

COOV features

• Total privacy – Based on blockchain technology, privacy is fully protected due to the fact that the usage history is not left on the server.
• Issuing digital certificates and verifying counterparties – Not only can the counterparty be given a digital certificate, but also verify the counterparty’s certificate using a QR scan.
• Various use cases through the provision of additional information – At the user’s choice, various additional information can be provided to the other party, in addition to the fact of vaccination.
• Used as national immunization system – It will be used as the system to confirm all vaccinations as well as to confirm vaccination against COVID-19.
• Free to use by governments and organizations around the world – We provide the global vaccination certification solution that underpins COOV to governments and organizations around the world free of charge. Global compatibility allows you to prove that you have been vaccinated against COVID-19 even abroad.
