Relay Overview
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 (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
What makes Relay privacy-preserving?
- Minimal disclosure — only the data needed to answer the claim question is shared and verified
- Claim results only — you receive a single eligibility result, nothing more
- Data deletion — Persona deletes verification data once the claim result is produced
- 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
