Indicio’s flagship product supports the issuance, holding, and verification of SD-JWT VCs, Europe’s choice of Verifiable Credential for privacy-preserving digital identity in the European Union Digital Wallet (EUDI).
By: Trevor Butterworth
By 2026, the European Union has mandated that every member country provide its citizens, residents, and businesses with a secure, interoperable digital wallet so that they can use Verifiable Credentials to prove who they are and share information across borders, platforms, and services, online and offline, across all EU member states.
For its Verifiable Credential format, the EU will use SD-JWT VCs.
What is SD-JWT VC?
The acronym stands for Selective Disclosure JSON Web Token Verifiable Credential.
A JSON Web Token is a standardized way to share digitally-signed information between parties. Selective disclosure means that this information can be shared selectively, thereby enabling a party to restrict the data they share to the specifics needed for a given purpose. Verifiable credential means the JWT includes the specific data formats as well as validation and processing rules required to express Verifiable Credentials.
Why is this important?
Simply put, it enables data privacy and increases security.
The easiest way to understand this is by looking at how we share information to access resources using physical credentials, like a driver’s license.
To verify age for purchasing an age-restricted item, a person would present a physical ID that contained their date of birth, typically a driver’s license, passport, or national ID card. But in presenting that ID, the person verifying it would be able to see all the personal data on the ID.
In an age of identity theft, this is no longer tenable. But it is also unacceptable in terms of data privacy. Selective disclosure is non-negotiable for the European Union. EU data privacy law — GDPR — requires organizations minimize the data they collect, process, and store to fulfill a specific purpose; selective disclosure makes minimization easy.
How to issue and verify SD-JWT Verifiable Credentials with Indicio Proven
Access Indicio Proven, either using its interface or its API, and connect your existing IAM, CRM, HR software, identity provider, API, or database. Select the SD-JWT VC from the menu and start issuing credentials.
Indicio Proven’s verifier software automatically accepts SD-JWT VCs, so you have immediate interoperability with all EU digital wallets..
Why go with Indicio Proven for your EU credential solution?
Indicio was the first to demonstrate interoperability between SD-JWT VC and AnonCreds credentials in a single workflow.
We’ll shortly enable similar interoperability with mdoc/mDL and W3C VC credentials.
Simply put, if you want to interoperate globally, Proven has proved itself in the real world.
There are two other important reasons for choosing Indicio Proven.
It enables you to scale rapidly to any level of issuance or verification.
It has the most powerful governance solution in the marketplace, allowing you to easily orchestrate credential roles, trust lists, and workflows in hierarchical ways.
And because governance is cached as a machine-readable file for each credential issuer, holder, and verifier, offline verification is possible using BLE, NFC, or Wifi Aware.
