Modular KYC for a Privacy-First Web3 Protocol Biometric Verification Without Storing User Data
Custom in-house KYC flow that needed modular, privacy-respecting OCR and biometric verification without storing user data or compromising their architecture.
Hypersign OCR, biometric, and liveness APIs integrated as modular components no PII stored, no architectural compromise.
Web3 Protocol came to Hypersign facing a real compliance challenge: their existing custom KYC flow needed to evolve. As a privacy-first protocol, the client couldn't adopt a vendor that would store user data or require them to send raw identity documents to a third-party server. They needed modular, composable APIs they could call on their own terms.
The Approach
Hypersign's modular API stack OCR extraction, biometric validation, and active liveness detection plugged directly into the protocol's existing pipeline. Each API call returns structured results without retaining raw identity data. The team maintained full control over data flow while gaining enterprise-grade accuracy for each verification step.
Key Outcomes
- ✓Privacy architecture preserved no PII stored by Hypersign
- ✓OCR accuracy and biometric confidence scoring added without rebuilding the pipeline
- ✓Liveness detection reduced identity spoofing risk significantly
- ✓Modular integration completed without changing the core user flow
What's Next
The team is exploring Hypersign's verifiable credential infrastructure to let users carry a privacy-preserving proof of verification across protocols verify once, prove anywhere.
