KYC/KYB Investigation: How to Reduce False Positives Without Letting Fraud Through

The KYC/KYB Paradox

In KYC/KYB onboarding, every false positive costs time, conversion, and sometimes legitimate customers. Every false negative costs financial and regulatory risk. The real challenge is therefore not to “maximize a score”, but to manage a defensible operational trade-off.

What the Field Investigation Shows

Across multiple flows, we observe three recurring causes of false positives:

• single thresholds applied to all document types;
• no segmentation by risk profile;
• human escalation that is too broad and not targeted.

In parallel, fraudulent files that get through often exploit documents that are “almost coherent”: visually credible enough, but inconsistent in the links between data (date, income logic, cross-identity checks).

Recommended Method: a 3-Level Pipeline

Level 1: fast triage

• Format/structure/metadata checks.
• Immediate blocking of obviously invalid cases.

Level 2: consolidated score

• Technical score + semantic score + business rules.
• Differentiated thresholds by document type and customer context.

Level 3: targeted expert review

• Escalate only ambiguous or high-impact files.
• Decision assisted by explanatory traces, not just a raw score.

How DeepForgery Helps Reduce False Positives

• Native segmentation: you can adapt analysis depth by flow.
• Operational explainability: triggering signals guide human review.
• Automatic routing: fewer unnecessary escalations on healthy files.
• Improvement loop: analyst feedback informs threshold tuning.

KPIs to Track Over 90 Days

Common Mistakes to Avoid

• Treat every file with the same detection aggressiveness.
• Confuse “model accuracy” with “overall operational performance”.
• Fail to measure the commercial cost of false positives.
• Fail to formalize a runbook for disputed cases.

Conclusion

Reducing false positives without opening the door to fraudsters requires active risk governance, not just an initial configuration. DeepForgery provides a technical and operational foundation to evolve this trade-off continuously and in a controlled way.
