Provium Proof
Verification that leaves no residue.
API-first identity verification for businesses. Receive cryptographically signed receipts — the data tier you choose, the compliance posture you need, the breach surface you eliminate.
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.
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 Provium. Full KYC/AML compliance.
Attestation-Only
Lightweight compliance receipts
Receive a signed attestation that a specific check was performed ("driving licence valid as of date"). No PII, no tokens — just auditable proof the verification happened.
Not sure which tier? Age-gated services start with Zero-Knowledge. Banks and regulated firms use Encrypted Token. Hospitality and car rental are typically Attestation-Only. The policy engine guides you through this during registration.

How it works
What you define
Industry re-verification examples
Children's ages change monthly; gambling regulations require frequent re-verification to detect age bracket transitions promptly.
Online Safety Act requires platforms to verify under-18 users regularly. Quarterly checks balance safety with user experience.
KYC regulations require periodic identity re-confirmation. Annual checks meet AML directive requirements.
Driving entitlements can be revoked or expire. Six-monthly checks ensure licence validity for insurance purposes.
