OpenID for Verifiable Credentials: Achieving interoperability, security and scalability
02-27, 11:30–12:00 (UTC), Ríma

Latest updates on conformance tests for OpenID for Verifiable Credentials family of standards, live demonstration of the current tests and discussion about planned future work.


Digital wallets and verifiable credentials are currently a hot topic in many jurisdictions around the world, with work ongoing in ISO, the EU, Japan, USA and many more that leverages the OpenID Foundation (OIDF) for Verifiable Credentials standards. OIDF has a history of creating conformance tests and certification programmes for OpenID standards that can be used to ensure that ecosystems made of up many potentially divergent implementations of the standard can scale up quickly.

OIDF is currently working on tests for the OpenID for Verifiable Presentations, OpenID for Verifiable Credential Issuance and OpenID4VC High Assurance Interoperability Profile (HAIP) specifications to ensure that deployments of these protocols are both interoperable and correctly implement the security properties. Joseph talks about the approach being taken, demonstrates the progress to date, shares the future roadmap and how implementors can run the current tests.

Joseph is a software engineer & architect with over 25 years’ experience, who started writing mobile apps before mobile apps existed.

He contributes to IETF and OpenID Foundation working groups, including the FAPI group where he helped write the security profiles used by most OpenBanking ecosystems and is a co-chair of the Digital Credentials Protocols working group. He’s helped companies around the globe architect and deploy secure systems, particularly when mobile apps are involved. More recently he’s been focussed on verifiable credentials, in particular the OpenID for Verifiable Credentials family of specs, along with the associated specifications like mdoc/mdl, SD-JWT VC and the interoperability profiles.

Joseph is CTO at Authlete and Standards Specialist & Certification Director at the OpenID Foundation.
