Context aware, pluggable and customizable data protection and PII anonymization service for text and images

Presidio (Origin from Latin praesidium ‘protection, garrison’) helps to ensure sensitive text is properly managed and governed. It provides fast analytics and anonymization for sensitive text such as credit card numbers, bitcoin wallets, names, locations, social security numbers, US phone numbers and financial data. Presidio analyzes the text using predefined analyzers to identify patterns, formats, and checksums with relevant context.

You can find a more detailed list here

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

Text anonymization in images

• Text analytics - Predefined analyzers with customizable fields.

• Probability scores - Customize the sensitive text detection threshold.

• Anonymization - Anonymize sensitive text and images

• Workflow and pipeline integration - Monitor your data with periodic scans or events of/from:

  1. Storage solutions
     • Azure Blob Storage
     • S3
     • Google Cloud Storage
  2. Databases
     • MySQL
     • PostgreSQL
     • Sql Server
     • Oracle

Note: Examples are made with HTTPie

Sample 1

1. Analyze text

   $ echo -n '{"text":"John Smith lives in New York. We met yesterday morning in Seattle. I called him before on (212) 555-1234 to verify the appointment. He also told me that his drivers license is AC333991", "analyzeTemplate":{"fields":[]}  }' | http <api-service-address>/api/v1/projects/<my-project>/analyze

Sample 2

You can also create reusable templates

1. Create an analyzer project

   $ echo -n '{"fields":[]}' | http <api-service-address>/api/v1/templates/<my-project>/analyze/<my-template-name>

2. Analyze text

   $ echo -n '{"text":"my credit card number is 2970-84746760-9907 345954225667833 4961-2765-5327-5913", "AnalyzeTemplateId":"<my-template-name>"  }' | http <api-service-address>/api/v1/projects/<my-project>/analyze

Sample 3

1. Create an analyzer project

   $ echo -n '{"fields":[{"name":"PHONE_NUMBER"}, {"name":"LOCATION"}, {"name":"DATE_TIME"}]}' | http <api-service-address>/api/v1/templates/<my-project>/analyze/<my-template-name>

2. Analyze text

   $ echo -n '{"text":"We met yesterday morning in Seattle and his phone number is (212) 555 1234", "AnalyzeTemplateId":"<my-template-name>"  }' | http <api-service-address>/api/v1/projects/<my-project>/analyze

Sample 4

1. Create an anonymizer template (This template replaces values in PHONE_NUMBER and redacts CREDIT_CARD)

   $ echo -n '{"fieldTypeTransformations":[{"fields":[{"name":"PHONE_NUMBER"}],"transformation":{"replaceValue":{"newValue":"\u003cphone-number\u003e"}}},{"fields":[{"name":"CREDIT_CARD"}],"transformation":{"redactValue":{}}}]}' | http <api-service-address>/api/v1/templates/<my-project>/anonymize/<my-anonymize-template-name>

2. Anonymize text

   $ echo -n '{"text":"my phone number is 057-555-2323 and my credit card is 4961-2765-5327-5913", "AnalyzeTemplateId":"<my-analyze-template-name>", "AnonymizeTemplateId":"<my-anonymize-template-name>"  }' | http <api-service-address>/api/v1/projects/<my-project>/anonymize

Sample 5 (Image anonymization)

1. Create an anonymizer image template (This template redact values with black color)

   $ echo -n '{"fieldTypeGraphics":[{"graphic":{"fillColorValue":{"blue":0,"red":0,"green":0}}}]}' | http <api-service-address>/api/v1/templates/<my-project>/anonymize-image/<my-anonymize-image-template-name>

2. Anonymize image

   $ http -f POST <api-service-address>/api/v1/projects/<my-project>/anonymize-image detectionType='OCR' analyzeTemplateId='<my-analyze-template-name>' anonymizeImageTemplateId='<my-anonymize-image-template-name>' imageType='image/png' file@~/test-ocr.png > test-output.png
