Zero-Knowledge KYC Proof
Zero-Knowledge KYC Proof delivers fast, defensible KYC decisions for UK businesses that cannot afford onboarding failures or regulatory exposure.
Overview
Zero-Knowledge KYC Proof is part of our UK KYC Verifier suite, engineered for businesses that need to onboard, screen and monitor customers without compromising on speed or compliance. The service is delivered through an API-first platform with hosted pages, mobile SDKs and webhooks, so it slots into any UK onboarding journey.
Privacy-preserving ZK proofs of age, residency and accreditation. The check is benchmarked against authoritative UK reference data and validated against a 2.4 million-record uk truth set with 99.6% accuracy. Every result is returned with a confidence score, the underlying evidence, and a signed audit log that satisfies FCA, HMRC and UKGC reviews.
What makes Zero-Knowledge KYC Proof different from a generic vendor check is its UK focus. We are not a US tool with a UK plug-in — our document templates, address sources, sanctions feeds and human reviewers are all UK-native. That focus produces materially higher accept rates for legitimate UK applicants while still rejecting the synthetic, tampered and stolen identities that drive fraud losses in the UK market.
How Zero-Knowledge KYC Proof Works
- 1
Capture
Your customer uploads or chips-in the required evidence through our hosted page, native SDK, or your own UI via our REST API.
- 2
AI Analysis
Our models extract, parse and forensically inspect every artefact — checking holograms, MRZ, NFC chip data, document templates and font kerning against a 240-country reference set.
- 3
Cross-Reference
We cross-reference the result against authoritative UK sources, sanctions lists and our internal fraud graph, raising flags on any inconsistency.
