Creating an app with a custom set of recognizers

[omri374]

I'd like to create Docker images with custom recognizers. How can that be done?

For example:

1. Can I modify the behavior of the crypto recognizer (or other [entities][(https://microsoft.github.io/presidio/supported_entities/) beyond what the ad hoc recognizers can do but then create a docker image from it that I can deploy as a sidecar and call using the /analyze api from my nodeJS app?
2. Can I customize the recognizers to use python RE2 when scanning for regexes instead of the python regex library you use?

First, you can configure exactly which recognizers are added to Presidio using the Recognizer registry. For instance, you can remove the existing Crypto recognizer, and add a new instance which is based on the updated code for crypto recognizer or remove the crypto recognizer altogether.

• More on adding recognizers: Tutorial - Microsoft Presidio.
• More on removing existing recognizers can be found here.

You can also add a new recognizer which uses re2 instead of regex if you create a recognizer through code: Rule-based recognizers - Microsoft Presidio

Lastly, you can set up Presidio locally with the set of recognizers you’re interested in and create a custom Docker image based on your code base. This documentation specifies how to do this: Installation - Microsoft Presidio. The only this worth making sure is that the Presidio application uses the right configuration when created. A new Presidio version uses configuration files to define this: app.py:44
