Claims Engine

Prove "over 18". Never see the ID.

Ingest raw attributes (documents, bank data, account records) once, then answer predicates such as "over 18" or "income above X" as signed claims. The raw attributes never leave.

02 · Use case

Age checks without collecting IDs

Who it's for: Online platforms under age-assurance laws.

Today

Age-assurance laws require platforms to check that users are adults, but collecting ID documents turns every platform into a store of sensitive data.

With Claims Engine

The user's ID is checked once by the Claims Engine. The platform asks one question, "over 18?", and gets back a signed yes or no. The document and birth date never reach the platform.

What you get

  • Compliance without collecting IDs
  • A signed answer the platform can verify
  • No sensitive documents to protect

03 · How it works

Four steps, all inside attested nodes.

  1. 01 · Ingest

    Raw attributes go in once, over a sealed channel.

  2. 02 · Ask

    A service asks a question, such as "over 18?"

  3. 03 · Answer

    The engine replies with a signed yes or no.

  4. 04 · Verify

    The service checks the claim's signature; the data never moved.

04 · Built in

What it inherits from the engine.

Claims Engine runs on the same confidential engine as every Calimero product, so it comes with the same proof.

  • Attested hardware. Clients verify the node's image before sending anything.
  • Sealed end to end. Nobody, including us, can read data inside a sealed node.
  • Signed receipts. Every answer can be checked offline, later, by anyone.
