IDMerit: hundreds of millions of identity records exposed

National IDs, addresses, phone numbers, and dates of birth across 26 countries — left in an unsecured database.

Proveium does not store personal data on its servers — there is no personal data to steal.

Why it matters

The cheapest data is the data you never had.

Every ID you hold is a liability

Major IDV providers have suffered large-scale breaches exposing hundreds of millions of identity records. Proveium isn't another vendor holding your customers' data — and you retain only what regulation requires.

Friction kills conversion

Consumers abandon sign-ups when asked for documents they can't easily produce. For returning users who already hold the credential, Proveium verifies in seconds.

Compliance shouldn't need a legal team

GDPR, KYC, AML, right to work, age verification — different rules per jurisdiction. Proveium applies the right technical checks automatically. Regulatory obligations remain with the regulated entity.

How it works

You define what you need. We prove it is met.

One API call from your platform. A cryptographic receipt back to you. The PII never arrives.

1

Send a verification request

Define what you need — age, identity, right-to-work, KYC tier. Send a request via API or a no-code link. No SDK required to get started.

2

Your customer proves it

They open Proveium ID and share a one-time cryptographic proof. No document uploads. Nothing leaves their vault except the proof itself.

3

You receive a receipt

Audit-grade confirmation of what was proved, signed and timestamped. Stored on your side. The underlying data never touches your servers.

Sign · Verify · Integrate

Once verified, the identity does the work.

Signing, compliance, and proof aren't add-ons bolted to the outside. They work because the identity underneath them is real.

Sign as a verified person

Every contract sent through Proveium is signed by the cryptographically verified individual — not a name typed in a box. The signature is bound to a liveness-checked, document-verified identity at the moment of signing.

  • Click-to-sign · draw · wet-ink, all identity-bound
  • Bulk send, templates, full audit trail
  • Verifiable long after the document was signed

◆ The receipt is the product

Every verification leaves a cryptographic receipt. Nothing else.

What your auditors see. What you store. What the user can revoke at any time. The data itself never touches your servers — the proof does.
