TrustGrid announced a new use case for its platform to provide citizens with a secure digital vaccine passport that can be stored on their smartphone. TrustGrid is an opt-in system where citizens can authenticate their identity and vaccination status and receive a QR code to show as proof of vaccination. The passport can then be shared via digitally signed consent by the user wherever it’s needed through an Android or iPhone app. The TrustGrid platform uses distributed ledger technology to create a distributed identity network to ensure greater accuracy and data security.
