Designing Redaction-Aware Content Pipelines for Sensitive Domains

Redaction-Aware Content Pipelines for Sensitive Domains

Content automation gets risky fast when source materials include private or regulated data. The safe design is not “generate then delete.” It is “detect and block before generation.”

Step 1: Classify inputs before they reach the writer

type Risk = 'public' | 'internal' | 'restricted';

function classifyInput(text: string): Risk {
  if (/ssn|passport|bank account/i.test(text)) return 'restricted';
  if (/client|invoice|contract/i.test(text)) return 'internal';
  return 'public';
}

Step 2: Apply topic-safe abstraction templates

function abstractCase(raw: string): string {
  return raw
    .replace(/\b[A-Z]{2}\d{6}\b/g, 'record_id')
    .replace(/\$\d+(,\d+)?/g, 'amount')
    .replace(/\b[A-Z][a-z]+ [A-Z][a-z]+\b/g, 'client_name');
}
