Global Digital Identity · Add-on

Prove the answer. Not the identity.

"Is this user over 18?" "Are they in an eligible jurisdiction?" "Do they have a valid credential?" The answer is cryptographically proven — the identity behind it is never disclosed. Your platform stays compliant. Your users keep their privacy. You store zero personal data.

For: eGaming · Alcohol & tobacco · Age-restricted content · Privacy-first platforms · Any service with age or eligibility requirements.

The compliance trap: verify users, store their data, become a target

Regulators say: verify age. GDPR says: minimize data. Your users say: don't track me. Today, these goals conflict. Every platform that verifies identity must store personal data — creating breach targets, compliance costs, and user friction. Zero-Knowledge Identity resolves this conflict by design.

Why Zero-Knowledge Identity
🎭

Selective disclosure by design

The user controls exactly which attributes are shared. Your platform asks a question — it gets a yes/no answer, cryptographically proven. No names, no birthdates, no passport numbers.

🔒

Zero personal data on your servers

You receive proof, not data. No passport copies, no biometric templates, no PII. GDPR data minimization isn't a policy — it's the architecture. What you don't store can't be breached.

Still fully compliant

The proof is cryptographic and auditable. In a regulatory review, you can demonstrate that every user was verified — without ever having accessed their personal data.

👤

User consent at every step

The user sees exactly what is being asked and confirms each disclosure. No silent background checks. Full transparency — the user is in control of their own data.

🌍

Works for 179 countries

Built on top of IdentiGate's verified identity. Any user who verified their passport can use zero-knowledge proofs — regardless of nationality.

One API call

Ask a question via API, receive a cryptographic proof. Same REST API as all other IdentiGate products. No ZKP expertise needed on your side.

How it works

Your platform asks. The user approves. We prove.

The user has already created their IdentiGate identity (one-time, 90 seconds). Now your platform needs to verify an attribute — without seeing any personal data.

1

Platform asks a question

Your platform sends an API request: "Is this user over 18?" or "Is this user in an EU jurisdiction?" or any attribute query. You define what you need — nothing more.

2

User sees & approves

The user's IdentiGate app shows exactly what is being asked: "Online Casino X wants to verify: Are you 18 or older?" The user reviews and confirms with PIN. Full transparency.

3

Cryptographic proof generated

IdentiGate generates a zero-knowledge proof from the user's verified identity data. The proof confirms the answer — without revealing the underlying data. No birthdate, no name, no passport number is ever transmitted.

4

Platform receives proof ✓

Your platform receives a cryptographic proof: "User is 18+ — verified." This proof is auditable, tamper-evident, and machine-verifiable. Your platform never touched any personal data.

What can be proven without revealing identity

Ask any yes/no question. Get cryptographic proof.

Question your platform asks What you receive What stays hidden
"Is user ≥ 18?"Yes ✓ (proof)Birthdate, age, name
"Is user ≥ 21?"Yes ✓ (proof)Birthdate, age, name
"Is user in EU jurisdiction?"Yes ✓ (proof)Country, address, passport
"Is user NOT from a sanctioned country?"Yes ✓ (proof)Country, nationality
"Is identity verified?"Yes ✓ (proof)Everything
"Is user a unique individual?" (no duplicates)Yes ✓ (proof)Everything

Your platform defines the questions. The user approves each disclosure. IdentiGate proves the answer. You never see, process, or store any personal data.

Built for these industries

When you need compliance without personal data

🎰

eGaming & online gambling

Gaming regulators demand age verification. GDPR demands data minimization. Your players demand privacy. With ZK proofs, your casino verifies every player is 18+ (or 21+) without storing a single passport, name, or birthdate.

No personal data means: no data breach liability, no GDPR compliance overhead for stored PII, and no expensive data protection infrastructure. You're compliant with gambling regulations AND privacy law — simultaneously.

Age-restricted content & DSA compliance

The EU Digital Services Act requires platforms to protect minors. The European Commission's age verification blueprint (2025) explicitly recommends privacy-preserving solutions with selective disclosure.

IdentiGate's ZK proofs are exactly what the EU envisions: a "mini wallet" that proves age without revealing identity. Platforms can verify age for alcohol, tobacco, adult content, social media sign-up — without becoming custodians of millions of passport copies.

🍷

Alcohol & tobacco

Verify age for online purchases without storing IDs. Same ZK proof, different threshold (18, 21, varies by jurisdiction).

💳

Finance & KYC-lite

Prove identity verification without sharing the identity. Perfect for low-risk onboarding tiers where full KYC is overkill.

📱

Social media

Age-gate sign-up (13+ or 16+ per country) without collecting children's data. DSA compliant from day one.

What makes this different

Not a standalone ZKP tool. Identity-backed proof.

Most ZKP solutions are standalone tools — they generate proofs, but the identity behind the proof comes from somewhere else (a national eID, a document upload, a facial scan). That means the ZKP layer is only as strong as the identity layer beneath it.

IdentiGate's zero-knowledge proofs are backed by passport-anchored, NFC-verified, split-key-secured identities. The same identity that creates court-ready AdES signatures also generates ZK proofs. It's not "someone claims to be 18" — it's "a passport-verified individual is cryptographically proven to be 18."

And it works for 179 countries — not just the EU27 where EUDI Wallets will operate.
