What is Text Anonymization?

Text anonymization is the process of removing or masking Personally Identifiable Information (PII) from a document or dataset. This is crucial for privacy compliance (like GDPR or HIPAA), allowing you to share information safely without exposing the identities of individuals or sensitive system details.

Anonymization Methods Explained

This tool offers four powerful ways to protect your data:

  • Placeholders: Replaces data with generic tags like [EMAIL] or [PHONE]. Great for maintaining readability.
  • Masking: Partially hides data, e.g., j***[email protected]. Useful when structure needs to be verified.
  • Blocks: Replaces sensitive info with solid blocks █████. Perfect for visual redaction.
  • Hashing: Replaces data with a consistent short ID. Useful for tracking unique entities without knowing who they are.
