PII Sanitizer
Purpose and Intent
The pii-sanitizer is a data protection tool designed to identify and mask Personally Identifiable Information (PII) from datasets, logs, or communications to comply with privacy regulations like GDPR and CCPA.
When to Use
- Log Scrubbing: Clean application logs before sending them to centralized logging platforms (e.g., ELK, Datadog).
- Dataset Preparation: Sanitize production data before using it in staging or training environments.
- Customer Support: Mask sensitive info in support tickets before sharing them with engineering teams.
When NOT to Use
- Encryption: This is a redaction tool, not an encryption tool. It is for removing data, not securing it for later retrieval.
- Structured Database Migration: While it handles some structure, specialized ETL tools are better for massive DB sanitization.
Error Conditions and Edge Cases
- False Positives: Strings that resemble PII (like internal serial numbers) might be accidentally redacted.
- Ambiguous Context: "Rose" could be a name (PII) or a flower; the tool may err on the side of caution.
- Encoding Issues: Ensure input text is UTF-8 to avoid detection failures on special characters.
Security and Data-Handling Considerations
- Zero Retention: Input data must never be saved to disk.
- Local Processing: Highly recommended to run this within a secure perimeter so sensitive raw data never leaves the local environment.
