Biometrics, handled carefully

Face Recognition Development

Face recognition is the most legally constrained thing we build. The engineering is well understood; the governance is where projects succeed or get shut down.

The problem

Verification versus identification — the distinction that matters legally

One-to-one verification and one-to-many identification are treated very differently by regulators.

Verification confirms that a person matches a template they enrolled themselves, with consent, for a purpose they understand — unlocking an account, completing KYC. This is widely permissible with proper consent and retention controls.

Identification searches a face against a database of people who may not have consented. This attracts far heavier restriction, is prohibited in some contexts and jurisdictions, and we scope such projects narrowly and with your counsel involved from the start.

Biometric data is specially categorised under GDPR, several US state laws and other regimes. We build consent capture, template encryption, retention limits and deletion workflows as core requirements.

  • Explicit consent captured and revocable
  • Encrypted templates stored — never raw images where avoidable
  • Liveness and anti-spoofing before any match
  • Retention limits enforced automatically
  • Deletion on request, propagated everywhere
  • Demographic performance tested across groups
  • Human review on any adverse decision
Use cases

Where we build it

KYC and onboarding

Selfie matched against an ID document with liveness verification.

Account recovery

Biometric confirmation as one factor in a recovery flow.

Workforce attendance

Site access and time recording, subject to local employment law.

Duplicate enrolment detection

Preventing the same person enrolling twice under different identities.

Access control

Facility entry for enrolled, consenting individuals.

Age estimation

Where regulation requires an age check without full identification.

How we deliver

Ten stages from first call to a system your team trusts

Every AI engagement runs this sequence. Small projects compress stages; regulated projects expand them. Nothing gets skipped silently.

Discovery

A working session with your operations and engineering leads to map the process, the systems it touches, and where the cost actually sits.

AI Opportunity Assessment

We score candidate use cases on data readiness, volume, error tolerance and payback, then rank them. Some come back "do not use AI for this" — you get that answer too.

Solution Architecture

Model selection, retrieval design, tool boundaries, data flow, failure modes and hosting topology, documented before code.

Proof of Concept

A narrow build against your real data to prove accuracy on the cases that matter, typically 2–4 weeks. Go / no-go decision at the end.

MVP

One workflow, end to end, in the hands of real users. Evaluation sets and quality thresholds are defined here, not retrofitted.

Production Development

Hardening: error handling, retries, fallbacks, cost controls, rate limits, observability, and a human escalation path for every automated decision.

Integration

Wiring into your CRM, ERP, HRMS, data warehouse, ticketing and messaging channels through APIs, webhooks and event queues.

Security Testing

Prompt-injection testing, access-control verification, PII handling review, dependency scanning and penetration testing before go-live.

Deployment

Staged rollout on your cloud or ours, with CI/CD, versioned prompts and models, and rollback in place from day one.

Monitoring & Optimization

Quality dashboards, drift detection, cost-per-transaction tracking and a retraining or re-prompting cadence agreed in writing.

Security & Governance

Security-conscious architecture, from the first design review

Enterprise AI fails on governance more often than on models. Every system we build is designed to support enterprise security requirements and to give your risk team answers rather than assurances.

Data privacy & residency

Your data stays in the region and tenancy you nominate. We architect for no-training-on-your-data configurations and document exactly which vendor endpoints see which fields.

Role-based access control

Retrieval and tool permissions inherit your existing roles. A user cannot surface a document through the AI that they could not open directly.

Authentication & authorization

SSO via OIDC/SAML, short-lived tokens for agent tool calls, and per-tool scopes so an agent holds the narrowest possible privilege.

Encryption

TLS in transit, AES-256 at rest, managed keys via your cloud KMS, and encrypted vector stores for embedded content.

API security

Gateway-level authentication, signed webhooks, IP allowlisting, request validation and quota enforcement on every exposed endpoint.

Audit logging

Every prompt, retrieval, tool call, model version and human override is logged with a trace ID, so any output can be reconstructed months later.

Data isolation

Per-tenant separation at the storage, index and key level for multi-entity groups and regulated environments.

Secure prompt handling

System instructions are server-side, user content is treated as untrusted input, and we test against prompt-injection and tool-abuse patterns.

PII protection

Detection, masking or tokenisation of personal data before it reaches a model, with configurable redaction policies per field.

Human approval workflows

High-impact actions — payments, refunds, contract sends, record deletion — route to a named approver instead of executing autonomously.

Monitoring & anomaly detection

Alerting on unusual tool usage, cost spikes, refusal rates and quality regressions.

Rate limiting & abuse control

Per-user and per-tenant throttles, spend caps and circuit breakers so a runaway loop cannot become a runaway invoice.

Secure deployment

Private networking, secrets in a managed vault, immutable builds, dependency scanning, and infrastructure as code.

FAQ

Questions enterprise buyers ask us first

Is face recognition legal to deploy?
It depends entirely on jurisdiction, purpose and consent. Consent-based one-to-one verification is broadly permissible under GDPR and most regimes with proper controls. Identification against a database of non-consenting individuals is heavily restricted and in some contexts prohibited. Illinois, Texas and other US states impose specific biometric requirements with significant penalties. We build the technical controls; your legal counsel must confirm permissibility for your specific use and markets. Ezulix does not provide legal advice.
How accurate is face matching?
Modern verification against a good-quality enrolled template is highly accurate under controlled conditions. Accuracy degrades with poor lighting, extreme angles, occlusion and low-resolution capture — and published performance varies across demographic groups, which is why we test across groups and report the results rather than quoting a single number.
What is liveness detection?
Verification that the face presented is a live person rather than a photograph, video replay or mask. It is essential — without it, a printed photo defeats the system. We implement passive or active liveness depending on your risk profile and user experience constraints.
How is biometric data stored?
As encrypted mathematical templates rather than images wherever the use case allows, with keys in a managed KMS, defined retention periods enforced automatically, and deletion workflows that propagate to backups.
