DIVOC - Digital Infrastructure for Verifiable Open Credentialing

DIVOC (Digital Infrastructure for Verifiable Open Credentialing) is an open-source platform developed by eGov Foundation that enables countries to digitally orchestrate large-scale health campaigns and certification programs. The platform implements the W3C Verifiable Credentials Data Model and uses PKI mechanisms for cryptographically signing digital certificates. Built with a microservices architecture, DIVOC operates on core principles of privacy-by-design, interoperability, and scalability.

The platform's key technical features include:

• QR code-based verifiable credentials using RSA and EDDSA signing algorithms
• Integration with the OpenSABER framework and Sunbird RC Registry for credentialing
• Support for multiple certificate distribution methods including:
  • Digital downloads via URL/email
  • Paper certificates with QR codes
  • Integration with health wallets and PHR systems
• Compliance with WHO DDCC:VS specifications and EU-DCC standards

Since its launch in 2021, DIVOC has seen significant adoption, particularly for COVID-19 vaccination credentials. Notable implementations include:

• Over 2 billion vaccination certificates issued across India's CoWIN platform
• Deployments in Sri Lanka, Philippines, Jamaica, and Indonesia
• Integration with DHIS2 health information systems in multiple countries

The platform is recognized as a Digital Public Good by the Digital Public Goods Alliance and continues to expand beyond COVID-19 use cases into broader health credentialing applications while maintaining its focus on open standards and interoperability.
