What is Microsoft Presidio?
Presidio is a data protection and de-identification SDK that helps ensure sensitive data is handled properly. It identifies and anonymizes credit card numbers, names, locations, social security numbers, Bitcoin wallets, US phone numbers, financial data, and more in text and images. It provides default or custom recognizers that use named entity recognition, regular expressions, rules, and checksums, and it can also connect to external PII detection models. It states that, because detection is automated, there is no guarantee that all sensitive information will be found. It is currently transitioning to a community-owned project.
