Redact Customer Data Before AI Analysis

Keep only fields required for the question, replace direct identifiers with stable tokens, and store the mapping outside the prompt.

Published September 22, 2026 · Dr. Connor Robertson

What to provide

A representative record, the business question, internal data classification, and approved handling rules.

Starting prompt

Identify fields essential to answer this question and propose a redacted example. Flag direct and indirect identifiers; do not retain names, account numbers, or free-text secrets.

Trial case

Provide a sample record with names, account numbers, and facts needed for analysis. The redacted version should remove identifiers while retaining only the fields needed for the stated question.

Review gate

The data owner checks whether combinations of remaining fields can reidentify a person and verifies approved tool use.

How to score the result

Sensitive fields included unnecessarily and analyses that remain useful after minimization.

Use the current approved source and keep it available to the reviewer. Check a small set of finished outputs against the previous process before adopting this workflow.
