Consular Proof Rails: Turning Embassy Attestations into Machine-Verifiable Credentials

Executive Summary

Embassy and consulate attestations are essential, but on paper they are hard to trust at scale. GLMVH binds each attestation to a case (Identity + Offer + Recruiter) as a verifiable credential with a QR for offline checks and a signed JSON for system-to-system validation. The outcome is a machine-verifiable chain-of-custody accepted by employers and regulators.

Principle: A proof is only as strong as its binding. We bind issuer → subject → terms → recruiter → time.

What Fails Today

• Paper endorsements cannot be replayed in audit or validated by machines.
• Scanning creates images, not proofs; tampering is difficult to detect.
• Attestations don’t reliably bind to the exact identity, offer version, and recruiting entity.

GLMVH Proof Model

Attestation Payload

• subject_id (biometric-anchored identity key)
• offer_digest (hash of the accepted offer JSON)
• recruiter_ref (license ID + risk score snapshot)
• issuer (consulate key ID + role)
• evidence (URI list: captured docs, interview notes)
• valid_from / valid_to, nonce, signature (JWS)

Outputs

• QR card for offline human checks → opens a short status page.
• Signed JSON downloadable by employers/regulators (API and portal).
• Audit replay via evidence log (append-only, hash-chained).

Verification Flow (UAE-First)

1. GLMVH verifies identity, offer, recruiter → produces case snapshot.
2. Consulate reviews the case and issues a digital attestation bound to that snapshot.
3. Employer scans QR or ingests signed JSON → instant accept/flag.
4. Any change to identity/offer/recruiter invalidates the previous proof and forces re-issue.

Interoperability & Security

• Signed payloads (JWS); checksum for file integrity.
• Role-scoped keys for consular staff; revocation list for compromised keys.
• Field-level redaction for PII minimization in shared proofs.

Impact

• For UAE regulators: audit-grade acceptance with instant revocation when needed.
• For employers: fewer disputes; faster onboarding; machine validation.
• For workers: clear, tamper-evident path that prevents contract substitution.
