Digital Credentials Harmonized Presentation - Editor's Copy

Abstract

This document specifies a harmonized protocol for the presentation of digital credentials, bringing together the credential presentation approaches of ISO/IEC 18013-5 and OpenID for Verifiable Presentations across multiple credential formats, including ISO mdoc and IETF SD-JWT VC.

Foreword

This specification has been jointly developed by members of ISO/IEC JTC 1/SC 17 WG 10 and members of the OpenID Foundation Digital Credentials Protocols (DCP) Working Group, under the OpenID Foundation's Digital Credentials Harmonized Presentation (DCHP) Working Group.

This is an Editor's Copy. It is a work in progress and is subject to change at any time.

Introduction

ISO/IEC 18013-5 (Device Request / Device Response) and OpenID for Verifiable Presentations (Authorization Request / Authorization Response) take different approaches to credential presentation. This document defines a harmonized digital credentials request protocol that brings these together, supporting both in-person and online presentation and the coexistence of multiple credential formats, including ISO mdoc and IETF SD-JWT VC.

The objective is to enable interoperability among the parties involved in the presentation of digital credentials while allowing existing deployments to continue to operate.
