# Relay Overview

> Privacy-preserving verification that returns only a claim result — not identity data.

## What is Relay?

Relay is Persona's privacy-preserving verification product. Instead of collecting and returning identity data, Relay confirms a specific claim — *is this person over 18? is this a real human?* — and returns only the result. Relay lets you get the answer you need to enforce your policies without having to directly handle PII.

Once a claim result is produced, Persona deletes the underlying verification data.

## How it works

Built on [Privacy Pass](https://datatracker.ietf.org/wg/privacypass/about/) (an open IETF standard), Relay cryptographically separates the verification step from the result redemption step — **so no single party ever sees both who a user is and what they're doing.**

When an end user hits a gated experience, Relay evaluates the configured requirement and runs a verification flow. Once complete, you receive a pass/fail claim result, without the underlying identity data.

## What each party knows

| Party                      | Knows                                                    | Does not know                                                          |
| -------------------------- | -------------------------------------------------------- | ---------------------------------------------------------------------- |
| **You (Persona customer)** | The claim result                                         | The end user's name, birthdate, documents, or any identity data        |
| **Persona**                | The end user's identity data needed to derive the result | Which platform requested the verification or received the claim result |

## What makes Relay privacy-preserving?

1. **Minimal disclosure** — only the data needed to answer the claim question is shared and verified
2. **Claim results only** — you receive a single eligibility result, nothing more
3. **Data deletion** — Persona deletes verification data once the claim result is produced
4. **Double-blind architecture** — cryptographically separates you and Persona, so that neither party can correlate the end user's website activity with their identity data — not just a policy promise
