What is Presidio

Presidio (Origin from Latin praesidium ‘protection, garrison’) helps to ensure sensitive data is properly managed and governed. It provides fast identification and anonymization modules for private entities in text such as credit card numbers, names, locations, social security numbers, bitcoin wallets, US phone numbers, financial data and more.

Goals

• Allow organizations to preserve privacy in a simpler way by democratizing de-identification technologies and introducing transparency in decisions.
• Embrace extensibility and customizability to a specific business need.
• Facilitate both fully automated and semi-automated PII de-identification flows on multiple platforms.

Main features

1. Predefined or custom PII recognizers leveraging Named Entity Recognition, regular expressions, rule based logic and checksum with relevant context in multiple languages.
2. Options for connecting to external PII detection models.
3. Multiple usage options, from Python or PySpark workloads through Docker to Kubernetes.
4. Customizability in PII identification and de-identification.
5. Module for redacting PII text in images (standard image types and DICOM medical images).

⚠️ Presidio can help identify sensitive/PII data in un/structured text. However, because it is using automated detection mechanisms, there is no guarantee that Presidio will find all sensitive information. Consequently, additional systems and protections should be employed.
