FinAuth is an identity verification SDK that delivers production-grade KYC and biometric authentication through a single REST API or a fully offline, hardware-bound SDK. It combines NIST FRVT #1-ranked face matching, iBeta Level 2 certified anti-spoofing liveness, document OCR supporting 200+ ID types, and AML watchlist screening. The platform offers two deployment models: a hosted Cloud API for instant launch and auto-scaling, and an Offline SDK for air-gapped, GDPR-sovereign environments where biometric data must never leave the network. FinAuth achieves 99.85% biometric match accuracy and under 10ms on-device inference speed, with GDPR, SOC 2, and ISO 27001 compliance.
What is FinAuth?
FinAuth is an identity SDK for production KYC and biometrics. It takes face images, ID documents, and liveness selfies as input, and outputs structured JSON decisions for face match, liveness, document OCR, and AML screening. The platform runs on cloud servers or on-device via a compiled offline SDK, and is developed by FinAuth (finauth.io).
