The future of digital credentials

mDocs

mDocs are based on the ISO/IEC 18013 technical specification series (which standardises Mobile Drivers Licenses, mDLs) while implementing the same underlying technology to create various types of mobile documents, as per ISO/IEC 23220.
Different industries are already collaborating to address specific use cases and requirements that will soon become commonly used credentials - use mDocs to stay ahead of the curve.

Capabilities
Issuer Authentication

Verifiers can authenticate the origin of a credential via a chain of certificates linked within the credential itself, all the way to its root certificate.

Device Authentication

Credentials are bound to a mobile device and enable verifying the binding between a credential and the mobile device used to present it.

Holder Authentication

Credentials can include a portrait picture of their holder, enabling the verifier to compare it with the person presenting them in person. This can be performed manually or using facial recognition technologies.

Flexible Usage Patterns

Credentials can be verified via both in-person and remote verification workflows, with support for both same-device and cross-device flows.

Selective Disclosure

Credentials enable holders to present only specific parts of their credentials to verifiers, based on the content of the request.

Session Encryption

Session-based encryption/decryption keys are established to secure both in-person and remote interactions.

Secure and interoperable

JSON credentials

JSON credentials are built on the W3C Verifiable Credential (VC) data model, enabling cryptographically secure digital credentials to be used in various interactions. This model supports a trust data-sharing framework, where signed and linked data can be used to establish trust across various contexts.

Capabilities
Credential Registry

Credentials can be stored in a registry that serves as an underlying infrastructure for creating a Verifiable Organization Network (VON).

Selective Disclosure

Credentials enable holders to present only specific parts of their credentials to verifiers, based on the content of the request.

Revocation

Issuers can adjust credential revocation status, and that information can be consumed by verifiers and other relying parties.

Compact and flexible

CBOR Web Tokens

CBOR Web Token (CWT) Credentials are used to represent cryptographically proven claims of data in a way that is compact enough to fit inside a QR code. They are ideal for scenarios requiring high information assurance but not necessarily high identity assurance about the entity presenting the credential.

Capabilities
Revocation

Issuers can adjust credential revocation status, and that information can be consumed by verifiers and other relying parties.

Flexible Formatting

Can be rendered as a QR code or PDF, as well as Apple and Google passes that can be stored in a digital wallet.

Compactness

The credential payload is small enough to fit inside a QR code.

Self-contained

All information required for verification is self-contained within the QR code, with no need for complex presentation capabilities from the holder.

Selective Disclosure

Credentials enable holders to present only specific parts of their credentials to verifiers, based on the content of the request.

Offline Verification

Ideal for rapid verification scenarios with and without reliable internet connectivity.
