Compliance you can prove
not just promise.

When you market credit cards and other financial products under fair-lending rules, deleting a protected field like age or race isn't enough — the model rebuilds it from related clues. Intelafy leaves protected data out before it scores anyone. Your compliance officer gets an exact record of what produced every score.

The fair-lending trap

Dropping a column doesn't delete the information.

A model built without an age or race field can still rebuild both from related clues — ZIP code, name, neighborhood. Fair-lending audits catch it only after the fact, once the model is already live. The problem is the approach itself, not how you patch it.

Delete the field, then train

  • Protected field removed before the model is built
  • Related clues (ZIP code, surname, neighborhood) rebuild it inside the model
  • Compliance is an after-the-fact audit — an estimate of what the model did, not a record
  • Scores from two different models can't be compared on the same scale

Leave it out, then score

  • Protected data is left out before any scoring happens
  • Nothing can rebuild it — the engine can't see what isn't there
  • Every score carries the exact, named features that produced it
  • One 0-to-1 scale across every product line
Property 04 · Compliance by construction

Structural exclusion, not column-dropping.

When the engine leaves protected data out, it's gone — the scoring process truly can't see it. Not "probably didn't use it." Can't use it. An auditor gets proof, not a promise.

Evidence pool tens of thousands of attributes — protected data excluded — EXCLUDED age · ethnicity gender · religion Score 0.0–1.0 Audit trail exact named features, per individual The engine physically cannot see excluded data
FIG 1Protected attributes leave the evidence pool before scoring — and the audit trail records exactly which features produced each score.
Explainability by construction

Explain a score in seconds — to a regulator.

When someone asks why a specific person scored highly, you don't reach for an after-the-fact estimate. The engine recorded the exact, named signals that drove that person's score at the moment it scored them. A direct record of the reasons — not a guess.

For your compliance team

Print the features behind any score. Prove the protected classes were never in the pool. Close the fair-lending finding with evidence, not narrative.
