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 stores no plaintext identity data on its servers — there is no trove of 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.
