OpenID

Open ID for Verifiable Credentials (OID4VC) Protocol that allows claims to be presented in the form of a verifiable credential on top of Oauth 2.0. OID4VC is a popular format in Europe that we provide to customers who need the capacity to interact with these systems. However, we note that this format is limited and does not provide the capacities that provide important benefits to financial service use cases due to the absence of secure, bidirectional communication (mutual authentication, notification and confirmation, security). Issuing and verifying credentials (such as SD-JWTs) via OID4VC in addition to using DIDComm broadens compatibility and increases flexibility when working with partners.

The OpenID communication protocols, consisting of OpenID4VCI (Verifiable Credential Issuance) and OpenID4VP (Verifiable Credential Presentation), are required by the European Digital Identity Architecture and Reference Framework and are included in the EUDI specification.

These protocols enable verifiable digital identity credentials to be issued to a digital wallet and then be presented from that digital wallet to a relying party for verification. Through these mechanisms, European citizens can use digital identity credentials to access government services, prove their age, hold mobile driver’s licenses, and cross borders.

In addition to our ongoing support for selective disclosure in AnonCreds, Indicio now also supports the new SD JWT (Selective Disclosure JWT) credential format. Selective disclosure is a feature that allows credential holders to present specific information in a credential for verification (instead of having to disclose all the information in the credential at once). This feature is key to meeting the European Union’s requirements for data minimization and privacy in eIDAS.
