Sphereon VDX Verifiable Data Exchange

Sphereon VDX, our Verifiable Data Exchange platform, enables you to quickly deploy solutions to share data.

  • Securely: data and documents are digitally signed by the issuer.
  • Privacy-preserving: data is held and controlled by the owner.
  • Thrustworthy: data is automatically validated by the recipient.
  • Interoperable: based on W3C and ISO open standards.


Sphereon VDX, the Verifiable Data Exchange platform

Based on open W3C standards and specifications for Decentralized Identifiers (DID) and Verifiable Credentials (VC), our data exchange solutions are globally interoperable and connect seamlessly with existing IAM and Business Applications using common OpenID Connect integrations, trustless self-issued OpenID Connect (SIOP), OpenID Connect for Verifiable Credential Issuance (OIDC4VCI), and OpenID Connect for Verifiable Presentations (OIDC4VP).

  • Quickly build and deploy solutions to share data and documents.
  • Guarantee that everything you share remains authentic. By digitally signing data and documents at the source.
  • Verify the authenticity of data and documents you receive.
  • Ingest and process them automatically into your backend systems.
  • Provide independent verification to others, with no need to provide access to your systems.
  • Protect the privacy of the subjects of the data: the people or organizations the data or documents are about:
    • By giving them the control over sharing them with others. Or not.
    • By allowing them to selectively share data with others.

The Sphereon VDX platform enables you to quickly deploy solutions to share data and documents in public administration, healthcare, finance, services, mobility, education and other industries.
