U.S.-based quantum dot producer Quantum Materials Corp (QMC) announced its blockchain-based QDX HealthID for transparency in disease testing and immunization for infectious diseases. The goal is to ensure the authenticity of health data and support individuals to re-join the workforce quickly.

Quantum dots are nanoparticles made up of semiconductor materials that emit different colors when illuminated by light. This color depends on their size and the way they were manufactured. QMC has developed a track and trace solution using quantum dots and blockchain to verify the origin of products and counterfeiting.

The authentication solution is combined with QDX HealthID for monitoring and tracking the outbreaks of diseases, such as the COVID-19. The solution authenticates individuals being tested, the persons administering the test, and the test kits.

… With the health data backed by blockchain, governments and health agencies can formulate new plans and safety measures to contain the spread of COVID-19 and other diseases. Additionally, individual users can assess their immunization passport using a mobile application. The app features color-coded indicators — green, yellow, and red. If the app shows the green indicator, the individual has clearance to interact in social and work environments. This indicator can be shared and authenticated by others using a QR code.

“The world must have a system that eliminates the fears and anxiety of not knowing who is able to return to work,” said Les Paull, CEO of QMVT, the unit responsible for sales and marketing of QMC’s innovations.

… Yesterday, Ledger Insights reported on the COVID Credentials initiative (CCI), which uses digital identity to develop “immunity passports”.
