H33 is a Quantum-Resistant Authentication & Privacy Infrastructure H33 is a post-quantum cryptographic API platform that lets enterprises authenticate users, verify identities, and process sensitive documents without ever exposing raw biometric or personal data. Built on Fully Homomorphic Encryption (FHE-BFV64), Zero-Knowledge Proofs, and NIST FIPS 204-compliant Dilithium-3 signatures, H33 is the first API-first platform to deliver military-grade privacy with full regulatory auditability — simultaneously. What H33 Does H33 replaces legacy authentication and document intake workflows with a privacy-native stack. All biometric matching and document validation run on encrypted data - a breach exposes nothing exploitable. The platform includes an AI-assisted contract validation interface that extracts fields from intake documents, highlights source text in context, confidence-scores each extraction, and routes human reviewers only to fields that need attention — eliminating manual re-keying while maintaining a complete audit trail. Core Capabilities Continuous multi-modal biometric authentication (facial, voice, keystroke, physiological) fused in real time. Zero-Knowledge Proofs verify identity claims without revealing underlying data. A Blockchain Compliance Orchestrator automates HIPAA, GDPR, and SOX requirements, compressing audit logs 5,000x via ZK-Merkle trees while remaining fully verifiable by regulators. Who It's For Security and engineering teams in regulated industries — healthcare, financial services, insurance, and government — handling PHI, PII, or sensitive credentials. Available as a metered API from Free (1,000 units/month) through Enterprise. Why H33 Is Different Most platforms force a trade-off between privacy and compliance visibility. H33 eliminates it. Biometric templates are encrypted at enrollment and matched entirely within the FHE circuit — never decrypted. Compliance logs are blockchain-anchored and provable via ZK proofs without exposing individual records. Quantum-resistant by design.
