Threat Modeling
We identify the critical assets and the attack vectors that reach them — biometric templates, cryptographic keys, authentication flows, and the final decision output. Together we map trust boundaries between sensor, secure compute, application, and backend, and agree on attacker profiles and success criteria, so test pressure matches your real exposure rather than a generic checklist.
Security Design Review
We assess architecture, data flows, and permissions for weaknesses. That means tracing data from capture to match to server consumption, examining dependencies including third-party libraries and platform services, and reviewing fallback and error handling — where bypasses usually live. We verify that claims are cryptographically bound, state transitions are explicit, and components validate one another's assertions.
Biometric Solution Analysis
We review the system for vulnerabilities and exploitable conditions across the biometric chain: liveness and matching logic, the integrity of the signal pipeline after capture, attestation and device-state handling, and how templates are stored and managed through enrollment, re-enrollment, and deletion.
Solution Testing
We test the solution for bypasses arising from hardware manipulation, software exploitation, or backend vulnerabilities. Controlled presentation attacks against the capture path, injection and replay within the signal pipeline, probing of application and API boundaries, and varying device state to test attestation and secure hardware binding. Every step is documented for reproducibility, so your team can replicate results.
Expert Interpretation and Guidance
We translate findings into actionable security improvements aligned with your goals, prioritized by impact and ease of exploitation — strengthening trust boundaries, improving biometric defenses, and removing permissive fallbacks. A targeted retest confirms the fixes close the intended gaps and helps identify regressions.
Biometric systems face threats at multiple layers of the pipeline. We examine the full chain to produce evidence you can use, whether in meeting compliance requirements or developer security standards.
Standards and Programs We Support
Keysight is an accredited EMVCo security laboratory for Software-Based Mobile Payment evaluations, including Consumer Device Cardholder Verification Method. If your biometric gates a payment on a consumer device, this is usually where your obligations start. We can run your biometric assessment as part of a wider SBMP evaluation.
Compliance Assessment and Security Testing covers mobile payment implementations where biometrics act as the cardholder verification step. We evaluate against CAST requirements and align the work with any parallel EMVCo or Visa activity so evidence is produced once.
Secure Device Connection Protocol sets requirements for fingerprint and face sensors that feed Windows Hello, covering the trusted path between sensor and host. We have evaluated fingerprint sensors against SDCP requirements for silicon and module vendors shipping into the Windows ecosystem.
Remote identity proofing under eIDAS 2.0 is pushing high-level PAD and IAD assurance into a hard requirement for Qualified Trust Service Providers and full-function EUDI Wallets. If you are building remote onboarding for the European market, injection resistance is becoming a market-access requirement.
FIDO's biometric component certification has extended beyond presentation attacks into injection attack detection. If your component will be assessed under this program, talk to us about where our evaluation work fits alongside it.
Biometric authentication in a connected product falls inside the CRA's secure-by-design, vulnerability handling, and technical documentation obligations. Where you already have a CRA or RED program running, biometric evaluation can be folded into that roadmap.
Working with Keysight
Twenty-five years of device security testing, applied end-to-end to the biometric chain..
Evaluate With an Attacker’s Mindset
Our team has spent decades finding real weaknesses in real embedded products, using side-channel analysis, fault injection, and hardware and firmware reverse engineering. That experience shapes how we scope, test, and advise — so your assessment reflects resistance to real-world attacks, not just a completed checklist.
Findings You Can Reproduce
Every step of our testing is documented, with reproduction steps, preconditions, and proof-of-concept artifacts for each finding. Your team can replicate the results directly, which speeds up resolution. Findings are prioritized by impact and ease of exploitation, and recommendations are weighed against user experience, performance, and cost.
Testing That Fits Your Compliance Goals
Accredited for EMVCo, Mastercard CAST, and Microsoft SDCP evaluations, we can align your testing with the requirements your partners expect. Getting attestation, template lifecycle, and decision flows right early makes certification go smoothly — so that formal evaluation validates what you already know instead of surfacing surprises late in the program.
