NeoLinkID

NeoLinkID is a mobile-based self-sovereign identity (SSI) solution developed to improve birth registration rates and mother-baby health record linkage in Kenya. The system leverages Sovrin Network and Hyperledger Indy blockchain technology to enable secure, verifiable credentials for birth registration while preserving privacy through selective disclosure.

The core technical implementation uses the Evernym SSI platform and includes three key components: a mobile web application for healthcare workers to issue credentials, an Android application for mothers to store credentials, and integration with the DHIS2 national health reporting system. The system uses verifiable credentials and decentralized identifiers (DIDs) to create cryptographically secure birth notifications that can be verified without requiring centralized infrastructure. Key features include QR code-based connection establishment between healthcare workers and mothers, offline capability, and the ability to selectively share specific credential data.

The project was developed through collaboration between the NeoInnovate Collaborative Consortium, University of Notre Dame, Cardiff University, and other partners, with support from the Evernym ID for Good Accelerator and Google Summer of Code. While initially focused on facility-based births in urban areas due to connectivity requirements, the system aims to eventually support community-based birth registration. The project represents an innovative approach to improving birth registration rates and mother-baby health record linkage while maintaining individual privacy and data sovereignty in low-resource settings.
