The Security Paradox of Traditional Biometrics

Conventional biometric systems create a fundamental contradiction: they protect access using data that, if breached, can never be changed. Server-side biometric storage creates honeypot targets. Device-native biometrics like Face ID authenticate the device, not the person — they do not meet multi-factor authentication standards because they only prove device possession, not user identity.

Zero-knowledge biometric architecture resolves this paradox entirely. No complete biometric template is ever created, stored, or transmitted — not on the device, not on the server, not anywhere in between.

Customer Authentication

For banks, fintechs, and digital platforms, zero-knowledge biometrics delivers a passwordless experience that simultaneously satisfies the highest regulatory authentication requirements:

• Secure Device Binding — Cryptographic keys tied to the device's secure enclave ensure that authentication is inseparable from a verified physical device
• Passwordless Login — Replace passwords and SMS OTPs with a single biometric action that authenticates both the user and their device in under 300 milliseconds
• PSD2 SCA & Dynamic Linking — Meet Strong Customer Authentication requirements with biometric verification cryptographically linked to the specific transaction amount and payee — mathematically irrefutable proof
• Step-Up Authentication — Elevate assurance levels for high-value transactions, sensitive data access, or privileged operations with seamless biometric challenge
• Account Recovery — Self-service account recovery in 30 seconds using true biometric identity, eliminating costly call center interventions and insecure SMS OTP recovery flows
• User Enrollment — Two enrollment paths: live enrollment via facial biometric capture with passive liveness, or bridged enrollment that leverages existing KYC/IDV biometric templates

Workforce Authentication

For enterprises pursuing zero-trust security, zero-knowledge biometrics eliminates the weakest link in workforce authentication — passwords and shared secrets:

• Passwordless SSO — Integrate with existing identity providers to replace passwords with facial biometrics across all federated identity management systems with a single selfie
• True Multi-Factor Authentication — Unlike traditional MFA that combines weak factors (password + OTP), this delivers two of the strongest factors — possession (device) and inherence (biometrics) — in one action
• Remote Access & VPN — Protect VPN logins with passwordless biometric MFA, compatible with all major VPN clients through standard RADIUS/SAML integration
• Shared Device Authentication — Enable employee authentication on any shared device with a front-facing camera. No passwords to remember, no physical tokens to carry — fully portable multi-user, multi-device capability

Industry Applications

Deployment Flexibility

Solutions deploy across any channel — in-app, web browser, or mobile browser — via cloud or on-premises infrastructure, with passive liveness detection that works on any device with a front-facing camera. Backend bulk enrollment enables large-scale workforce deployments without individual device provisioning.
