Verification that leaves no residue.
Receive cryptographically signed identity proofs without storing documents or biometrics. Three data tiers, eight check types, automated re-verification schedules.
REST API · OpenAPI spec · free sandbox, unlimited test calls
Built on open, auditable standards — your legal and security teams can verify every claim independently.
Choose Your Data Tier
Match your data handling to your risk appetite and regulatory requirements. Every tier includes a signed verification receipt.
Zero-Knowledge
No PII touches your servers
Receive a boolean assertion ("over 18: true") backed by a cryptographically signed receipt. Ideal for age verification, eligibility checks, and any scenario where you need proof without data.
None. Only the signed receipt.
Encrypted Token
PII available when regulation requires it
Receive an encrypted identity token you can decrypt and retain per your regulatory obligations. You hold the decryption key, not Proveium. The verified identity data your compliance process needs.
Encrypted token (you hold the key).
Attestation-Only
Signed proof a check was performed
A signed attestation that a specific check was performed ("driving licence valid as of date"). No identity data exchanged — just auditable proof the verification happened.
Receipt and claim type only.

Proof-Type Re-Verification Cycles
Define which identity proofs you need, why you need them, and how often they must be re-verified. The system enforces your configured schedule automatically — recommended defaults reflect regulatory best practice. You retain responsibility for verifying compliance with your specific obligations.
Define proof requirements
Declare each proof type, the legal basis, and your preferred re-verification interval during registration.
System applies guardrails
Regulatory minimums for your industry and country are compared against your requested interval. The most restrictive wins.
Schedule attached to consents
When a user grants consent, the re-verification schedule is automatically attached with the first due date tracked.
Automatic notifications
When re-verification is due, the user receives a push notification. Overdue responses are flagged as stale automatically.
Re-Verification Examples by Industry
| Industry | Claim | Interval | Why |
|---|---|---|---|
Gambling & Gaming | age_bracket | 30 days | Gambling platforms re-verify age brackets regularly to detect transitions. Specific intervals depend on your UKGC licence conditions. |
Social Media | age_bracket | 90 days | Platforms subject to the Online Safety Act re-verify age-band status periodically. Ofcom has not prescribed a fixed interval — configure to match your compliance posture. |
Banking & Finance | identity | 365 days | Regulations require periodic identity re-confirmation — your compliance team uses fresh verified data for ongoing due diligence obligations. |
Car Rental | driving_licence | 180 days | Driving entitlements can be revoked or expire. Six-monthly checks ensure licence validity. |
Three rules that cannot be bypassed
System-level rules set the minimum re-check frequency per claim type and industry. You can be stricter, never more lenient.
No proof type can go longer than one year without re-verification. Prevents "verify once and forget" for any claim.
If an auto-approved re-verification detects low confidence or a bracket change, the system automatically reverts to manual review.
Every check your compliance team needs — no PII surprises.
Eight check types, each mapped to a data tier so you know exactly what your servers receive before you build.
