In the Issuer-Holder-Verifier Model, Issuers issue Digital Credentials to the Holder’s Wallet, which the End-User can then use to present the Digital Credentials to the Verifiers. Digital Credentials are cryptographically signed statements about a Subject, typically the Wallet Holder. Verifiers can check the authenticity of the data in the Digital Credentials and optionally enforce Key Binding, Biometrics Binding and/or Claim-based Binding i.e., ask the Wallet to prove that it is the intended Holder of the Digital Credential.

The goal of this WG is to develop OpenID specifications for the Issuer-Holder-Verifier-Model use-cases to enable issuance and presentations of the Digital Credentials of any format (IETF SD-JWT, ISO/IEC 18013-5, etc.) and pseudonymous authentication from the End-User to the Verifier.

These specifications are aimed at allowing End-Users to gain more control, privacy, and portability over their identity information; cheaper, faster, and more secure identity verification, when transforming physical credentials into digital ones using digital credentials; and a universal approach to handle identification, authentication, and authorization in digital and physical space.

The work is planned to be done in liaison with the European Commission, Decentralized Identity Foundation (DIF), the European Telecommunications Standards Institute (ETSI), and ISO/IEC SC17 WG4 and WG10, which have expressed interest in profiling specifications proposed to be worked on in this WG. There is also a liaison with the OpenWallet Foundation (OWF), to foster implementation of the standards developed by this WG.
