The OIX Interoperability Guide provides ‘how to’ guidance for anyone interested in assessing how different identity ecosystems interact. It sets out a clear, adaptable approach to assessing interoperability of identity proofing and authentication carried out in different regional or national trust frameworks.
Building on the evidence of approaches to assessing and communicating interoperability taken in other sectors, and building on the preceding Guide to Identity Proofing and Authentication, the Interoperability Guide provides a structured approach to assess interoperability between identity trust frameworks, and to assess the equivalency of identity levels across different trust frameworks, covering all of the key elements of identity proofing and authentication.
The Interoperability Guide:
- Defines interoperability for digital identity proofing and authentication, based on previous applications, including from other sectors.
- Sets out the key considerations for anyone carrying out or acting on the results of interoperability assessment, such as relying parties, standard setters, identity providers, trust framework operators, authorities or assessment practitioners.
- Provides guidance on a specific approach to assessing interoperability, including an assessment structure for assessing compatibility between trust frameworks, and the degree of equivalency between identity levels.
- Gives guidance on methods to communicate the degree of interoperability.
- Provides guidance for interpreting and acting on interoperability assessment scores.
