Today the Illinois Blockchain Initiative announced its partnership with self-sovereign identity solutions leader Evernym, leveraging distributed ledger technology to provide secure digital identity solutions. The concept will augment work from the W3C’s Verifiable Claims Task Force and use the Sovrin Foundation’s distributed identity ledger to create a secure, “self-sovereign” identity for Illinois citizens during the birth registration process.
A formal announcement will be made on Sept. 1 by Evernym’s Chief Trust Officer Drummond Reed at the MyData2017Conference in Helsinki, Finland.
Self-sovereign identity refers to a digital identity that remains entirely under the individual’s control. A self-sovereign identity can be efficiently and securely validated by entities who require it, free from reliance on a centralized repository.
Jennifer O’Rourke, Blockchain Business Liaison for the Illinois Blockchain Initiative commented, “To structurally address the many issues surrounding digital identity, we felt it was important to develop a framework that examines identity from its inception at child birth. Government has an important role to play in the development of any digital identity ecosystem. Identity is not only foundational to nearly every government service, but is the basis for trust and legitimacy in the public sector.”
In the proposed framework, government agencies will verify birth registration information and then cryptographically sign identity attributes such as legal name, date of birth, sex or blood type, creating what are called “verifiable claims” or attributes. Permission to view or share each of these government-verified claims is stored on the tamper-proof distributed ledger protocol in the form of a decentralized identifier. The identifier guarantees each attribute is cryptographically sealed and only accessible with explicit consent of the identity holder or in the case of a newborn child, his or her legal guardian.
Businesses and governments will be able to verify and authenticate citizens by requesting encrypted access to these verifiable claims. This minimizes the need for entities to establish, maintain and rely upon their own proprietary databases of identity information.
“This architecture allows us to bridge the best of both worlds, combining government’s robust infrastructure for identity verification with a platform engineered for the digital identity ecosystem. This digital identity system is extensible, interoperable and at the same time ensures the utmost security, privacy and user-agency,” said Cab Morris of the Illinois Blockchain Initiative. “Additionally, this model for digital identity can extend beyond the boundaries of government and has broad applicability for many products and services in the private sector.”
“The successful transition to an identity ecosystem that is truly self-sovereign requires conversion of ‘breeder documents’, such as birth certificates, which serve as the basis for obtaining other documents,” said Evernym’s Drummond Reed. “Digitizing these foundational documents in a state the size and importance of Illinois will make a major contribution to the larger effort of solving the online identity problem.”
