Why the bank needs an eKYC platform

Onboarding, periodic refresh, sensitive transaction step-up, partner verification — all need identity verification. Without unified capability — every flow with its own stack.

eKYC platform — reusable, callable from multiple scenarios.

Structural components

Document capture with UX guidance, quality detection.

Document validation. OCR + structural (form, holograms, MRZ). Fraud detection.

Biometric capture. Selfie with ML models for local population.

Face matching. Selfie ↔ document.

Liveness detection. Active or passive — anti-spoof.

Registry checks. OMS, sanctions, blacklists, PEP.

Risk scoring. Combined score → decision: pass / step-up / decline.

Audit trail. Full evidence chain per verification.

Reuse layer. Existing identity reusable for new product activation.

Banking-specific concerns

Regulatory. cbu.uz biometric requirements from April 2026 — mandatory.

KYC level differentiation. Basic vs enhanced — different thresholds.

Beneficial ownership for corporates. Multi-step KYC.

PEP screening — ongoing, not one-time.

Suitability assessment — for investment products.

Where it usually breaks

Multi-vendor stack without unified accountability.

OCR works on 80% of documents, manual queue grows.

Liveness outdated — deepfake gets through.

Registry API unstable — eKYC stops.

Reuse not implemented — repeat KYC frustrates customers.

Operating model

Owner — Head of Identity / Head of Trust.

Teams: platform engineering, identity science, compliance, partnership integration.

Routine — monthly pass/fail/step-up rates, fraud incidents review.
