Six developing countries – Sri Lanka, Morocco, the Philippines, Guinea, Ethiopia and the Togolese Republic – are using an Aadhaar-like, open-source system to provide digital identities to their citizens. The platform was built by the International Institute of Information Technology, Bengaluru (IIIT-B), a non-profit headed by Infosys cofounder Kris Gopalakrishnan.
A digital identity system is one of four building blocks identified as important for digital government, along with a data collection and management platform, a digital payments capability and core data registries.
The Philippine Government's vaccine certificate is based on the Digital Infrastructure for Vaccination Open Credentialing (DIVOC) created in India, used as a reference system by the WHO's Digital Documentation of COVID Certificates (DDCC). It uses private and public-key cryptography and is interoperable with authorised wallet applications.
