Data space wallets for persons - Personal wallets

Integrate personal data space Identity Wallets (EUDI-ready) in your data space

Give individuals control and ecosystems interoperability.
Onecub designs and deploys personal data space wallets that plug into your data space infrastructure and align with the EU Digital Identity framework (eIDAS 2 / EUDI Wallet). The result: standard privacy and confidentiality-preserving, consent-driven data sharing across organisations, without centralising personal data.

What it is?

A EUDI Identity Wallet and consent layer for data spaces that lets people prove who they are, share only what’s needed, and reuse their information across services, while organisations meet regulatory requirements and keep their existing tech stacks.

What it enables?

Frictionless onboarding & “Once Only” journeys (no repeated form-filling).
Cross-organisation data-sharing with auditable GDPR consent and policy enforcement.
Trustworthy AI assistants that act with user mandates and full traceability.

Capabilities

1) Personal identity federation

Account linking across services & brands: reconcile and bind user accounts from multiple organisations to a single wallet identity.

State ↔ private-sector bridge: connect state-level identity (EUDI Wallet credentials, FranceConnect, etc.) with private sector identities in all sectors.

Standards-aware federation: interoperate across prevailing identity frameworks and data space stacks (e.g., SSO patterns, verifiable credentials, connector ecosystems, SSI, Solid, etc.).

Privacy and confidentiality-preserving data clean rooms: compute insights and matches without exposing raw personal data between data space participants.

2) Personal data-sharing control

GDPR-grade consent for cross-organisation sharing (purpose, scope, duration, revocation).
Elegant UX: consent buttons, popups/popins, QR codes, and deep links embedded in your web & mobile apps.
Centralised consent dashboard: a single place for individuals to view, modify, or revoke all active sharings, with tamper-evident logs.
Mandates & delegation: wallet-based authorisations that allow trusted third parties, including AI agents, to act on the user’s behalf, within explicit scopes.

3) Standard data wallet (EIDAS 2 / EUDI-compatible)

Credential vault: store, present, and refresh identity credentials (e.g., attributes, proofs, attestations, certificates).
“Once Only” data reuse: securely re-use key personal data across services without re-entry.
Trust services ready: integration paths for qualified signatures/seals and certified trust-service providers in line with eIDAS 2.

4) Interoperability, security & compliance

Data space native: integrates with data space collaboration platforms, catalogues, decentralised connectors, and policy engines; no data-lake dependency.
Sovereignty by design: keep data at the edge; encrypt in motion and at rest; strict purpose limitation.
Regulatory alignment: eIDAS 2 / EUDI Wallet, GDPR, and data space Rulebooks (usage control, auditability).

White-label & integration

We tailor our wallets to your stack and platforms—natively speaking EDC/Dataspace Protocol (DSP), Prometheus-X, iSHARE, FIWARE, and other sector standards—while preserving governance, security, and user experience. Delivered as a white-label solution under your brand.

Key project

MyTravelConnect: Onecub is building the personal identity & consent wallet for the EONA-X mobility and tourism data space. MyTravelConnect will be the default personal data-sharing and identity component for Gen4Travel AI agents and assistants, within the EONA-X tourism and mobility data space.

Key partners

Onecub develops personal data space wallets with Themis-X (joint venture with Digital New Deal) and Docaposte (Groupe La Poste), a European leader in digital trust and identity. Within EONA-X, our wallets interoperate with Amadeus data space connectors built on Eclipse Dataspace Components (EDC) and with VISIONS personal-data connectors compliant with Prometheus-X.
