ZERO-KNOWLEDGE IDENTITY VERIFICATION
Verify,
don't collect.
Confirm your users are eligible, without ever obtaining their personal data.
USER'S ID · STAYS ON THE PHONE
EVERYTHING THE BUSINESS RECEIVES
PRIVACY
Privacy
Personal data never leaves the user's phone; the business receives only a pass or fail. No personal data on your servers means none to leak.
ANTI-FRAUD
Fraud Prevention
Edited IDs, fake documents and accounts opened in someone else's name cannot pass verification, cutting fraud and identity theft at the source.
VERIFIABLE
Verifiable
Every proof can be checked mathematically, so a fake is caught instantly. With third-party audits and source code review, the system itself stands up to scrutiny too.
01 · THE PROBLEM
Collecting IDs costs more than you think
Breach risk and legal liability
Storing ID images means holding data on your users that could leak at any time, along with the legal liability that comes with it.
Time and staff for manual review
Checking documents one by one takes staff time, and the slower the review, the longer users wait.
Users dropping out of sign-up
Asking for an ID upload makes many users abandon sign-up halfway through.
02 · HOW IT WORKS
Prove you're over 18
without showing your birthday
A zero-knowledge proof lets a user prove that a statement is true while revealing nothing else. The business gets the answer, but never the data.
STEP 1
The phone reads the ID
The user's phone reads a Citizen Digital Certificate, an e-passport chip, or a credential from a digital wallet. The data never leaves the device.
STEP 2
A proof is generated on the phone
The phone computes a mathematical proof locally that answers only one question: does the user meet the condition?
STEP 3
The business receives only the result
The business verifies the proof and learns pass or fail, without touching any personal data.
INTERACTIVE DEMO
Simulate an "age 18 or over" check
USER'S PHONE (LOCAL)
The birthday is used only here and is never sent.
BUSINESS SERVER RECEIVES
No birthday, no name, no ID number.

Verification modules and use cases
It's not just government IDs. The email, online banking and login accounts users already have can all serve as data sources for zero-knowledge proofs.
SOURCE A
Based on government IDs
Citizen Digital Certificate, e-passports and digital credential wallets
A1
E-passport · Citizen Digital CertificateNationality Verification
Scenario
A ticketing platform confirms at checkout that each buyer is a real, named Taiwanese national, so scalpers can't grab tickets with masses of fake accounts. A subsidy platform can likewise confirm an applicant is a citizen without first collecting their ID number.
A2
E-passport · Citizen Digital CertificateAge Verification
Scenario
At checkout on an online liquor store, a shopper proves they are an adult in seconds on their phone. The merchant stays compliant without ever learning the shopper's birthday.
A3
Digital credential walletCredential Verification
Scenario
When renting a car online, users prove they hold a driver's license without revealing its details. At convenience-store pickup, a telecom SIM credential proves only the name and last three digits.
SOURCE B
Based on existing digital data
Email, website data and login accounts
B1
zkEmail · DKIMEmail Verification
Scenario
A rental platform lets a new hire prove an upcoming start date with the offer email from their employer. The system verifies the email was signed by the company's mail server and hasn't been altered, without seeing anything else in it.
B2
zkTLSTLS Verification
Scenario
A loan or rental applicant logs in to their own online bank and proves their balance is above a threshold. The business never gets their login credentials and never sees the actual amount or transactions.
B3
zkLogin · OIDCOAuth Verification
Scenario
An employee perks platform lets users prove with their work account that they belong to the company's domain. The platform learns only that they work there, not who they are.
