Singapore has developed a blockchain-based standard for the verification of Covid-19 tests, according to local reports. This standard is expected to make it easy for the government to verify health documentation within its borders.
Blockchain-based standard for Covid certificates
Vivian Balakrishnan, Minister of the Singapore Smart Country Initiative, announced that blockchain-based digital standards have been developed to publish Covid-19 test results. The digital solution known as HealthCerts uses blockchain technology to create an immutable digital standard.
The solution was developed by the Singapore State Technology Agency (GovTech) and the Ministry of Health (MOH).
HealthCerts complies with local and global standards and is designed to accelerate the migration process of travelers across local and foreign borders.
Passengers who pass COVID 19 tests prior to departure within Singapore will receive their results via digital certificates issued by HealthCerts. This certificate will be in the form of a link or attachment.
When the test is negative, travelers will be asked to upload the clinic’s digital certificates to a website Notarise.
The Notary ensures that digital certificates are verified and recognized at local and foreign airports. After successfully submitting the certificates, passengers will receive a notarized digital copy of their covid-19 test certificate containing a QR code. Once completed, passengers can present their notarized certificates or QR codes at airports and immigration checkpoints.
After the QR code is scanned, airline staff and immigration officials will verify the authenticity of the certificate based on the information stored on the blockchain. The test results will also be presented on the Singapore mobile ID mobile application SingPass.
HealthCerts is built on an open source framework called OpenAttestation built on blockchain. It verifies the information without the need for third party software. The Singapore government is also considering expanding the use of HealthCert for vaccine certificates.
