UbID Public Profile
Your identity. Your terms.
A cryptographically signed, visitor-facing professional presence at your own *.ubid.app address — showing only what you choose to publish, verifiable by anyone.
What Your Public Profile Shows
A curated, signed public projection — never your full credential store.
Professional Identity
Avatar, display name, headline, availability, verified DID, and a shareable public card code.
QR Code & Card
A scannable QR code and a downloadable professional card (PNG/SVG/PDF/vCard) that visitors can save and share.
Trust Center
Hybrid signature verification — classical ES256K and post-quantum ML-DSA-65 — plus DID-binding confirmation and a profile fingerprint.
Contact & Business
Public contact channels, professional networks, and an optional Business Center for professional requests — all holder-controlled.
Credential Summaries
Selected credential highlights published by the holder. Full SD-JWTs, private keys, and protected documents are never exposed.
Request Identity Proof
Visitors can trigger a consent-based OpenID4VP flow through Vault and Verifier to request verifiable proof directly from the holder.
Cryptographic Trust, Readable by Anyone
The Trust Center verifies the signed public projection in real time — no account required.
Hybrid profile — Verified
The required profile-signature policy passed.
Classical signature — ES256K
The classical cryptographic signature is valid.
Post-quantum — ML-DSA-65
The post-quantum signature is valid and future-proof.
DID binding — Confirmed
The identity address and subject DID match the signed profile.
Public projection fingerprint
A sha256 digest that uniquely identifies the exact projection being displayed.
Multilingual by Default
Visitors can switch between EN, ES, and PT directly on the public profile page — without modifying the holder's source data.
The Digital Professional Card
Every UbID Public Profile generates a verifiable professional card. Export it in the format you need — or scan the QR to open the live profile and verify it before relying on it.
- Download PNG — Perfect for messaging apps, slide decks, and everyday documents.
- Download SVG — Scalable vector — ideal for print and high-resolution output.
- Save as PDF — Browser-native print dialog with a clean, DID-preserving layout.
- Save contact — Exports a vCard (.vcf) with the holder's public contact data.
- Share — Opens the native device share menu or copies the localized profile link.
The Business Center
When a holder enables professional availability, visitors can send structured requests — Professional contact, Commercial proposal, or Meeting request. All sender data is encrypted before storage and delivered to the holder's private Issuer inbox.
- Choose request type: contact, proposal, or meeting
- Short-lived protected challenge prevents spam
- Sender data encrypted before storage
- Delivered to holder's private authenticated inbox
- Never part of the public profile
What Is Never Public
The public profile shows only the signed public projection that the holder explicitly selected and published. Review every field marked Public in the intranet before publishing.
