Three companies are developing a blockchain-based COVID-19 health passport that will help governments to monitor the population’s state of immunity in real-time.
Decrypt reports that positive test results will be timestamped to ensure it cannot be falsified.
The passport will run on the KSI blockchain developed by Estonian blockchain company Guardtime. Swiss security company SICPA and French health platform OpenHealth, which maintains a database of 20 million French patients, are also working on the project.
“The KSI blockchain will make it impossible to falsify and the health data on these certificates will be used by the OpenHealth platform to follow the evolution of deconfinement and management of the crisis, following the model of flu pandemics,” SICPA said in a press release.
Participants need only a smartphone or a computer to sign up, and all personal data is anonymised.
Decrypt reports some technology experts warn that government-run coronavirus apps are a “privacy disaster in the making.”
