Identity Verification Confidence Score Calculator
Calculate a composite identity verification confidence score (0–100) based on document quality, biometric match strength, data consistency, and risk signal penalties. Used in KYC, onboarding, and fraud prevention workflows.
Formula
Step 1 — Component Scores:
Doc Score = Document Quality (0–100) × Document Type Weight
Bio Score = Biometric Match (0–100) × Liveness Weight
Data Score = Data Consistency (0–100)
DB Score = Database Check Result × 100
Step 2 — Weighted Base Score:
Base Score = (0.25 × Doc Score) + (0.35 × Bio Score) + (0.25 × Data Score) + (0.15 × DB Score)
Step 3 — Risk Penalty:
Total Penalty = Number of Risk Signals × Penalty per Signal
Step 4 — Final Confidence Score:
Score = clamp(Base Score − Total Penalty, 0, 100)
Thresholds:
≥ 80 → High Confidence (Approve) | 60–79 → Medium (Review) | 40–59 → Low (EDD) | < 40 → Reject
