For Developers
Open-source Zero Trust biometric infrastructure
VoiceLock combines a browser-based WASM client, gRPC-Web gateway, and a Zero Trust Expert System backend that separates data processing concerns for dynamically controlled employment on multiple separate networks and containers. Configuration is policy-driven using an XML defined data structure which supports Information Security Markings (ISM) for oversight, verification and governance.
Architecture
The platform is split across subdomains:
- voice-lock.com — this landing site
- start.voicelock.com — demo / marketing shell (no persistent profile storage)
- owner.voice-lock.com — full WASM application with local profile storage
- dashboard.voice-lock.com — oversight and system monitoring
Open-source stack
- voicelock — voice biometric engine (native server + WASM client)
- ztlb — Zero Trust Library (Key, File, Ledger, Orderwire, Policy, Oversight services)
- gateway — gRPC-Web bridge for browser access to ZT services
Key principles
- Biometric processing stays in the browser; only hashes and metadata go on-chain
- Policy XML defines all network endpoints — nothing hardcoded
- Immutable ledger for audit trails; mTLS for network isolation
