Introduction to Privacy Purger

This specialized software component identifies and redacts Personally Identifiable Information (PII) from unstructured input texts, rendering them fully depersonalized for secure transmission to external platforms such as Large Language Models (LLMs). While this service serves as a core pillar of the ConSol CM/AI Assist subscription to ensure GDPR compliance, it is also available as a standalone license for integration into independent enterprise infrastructures.

To obtain your API key, please contact our ConCol CM support team.

Linking the application.yml to Docker Compose

In order for the application.yml to be loaded at startup, please uncomment and configure the following lines in the docker-compose.yml file to match your setup.

### Uncomment and configure volumes
    volumes:
      - type: bind
        source: ./application.yml
        target: /app/application.yml

    environment:
      # ...
      # Uncomment and configure Spring-Config
      - SPRING_CONFIG_LOCATION=file:/app/application.yml

Load the images using the following commands:
```
docker load --input privacy-purger-app:1.0.0.tar
docker load --input privacy-purger-ner:1.0.0.tar
```
hinweis
The ner image is large in size, so the loading process may take a few moments.
Verify that the images have been loaded successfully by running:
```
docker images
```
You should now see the privacy-purger-app and privacy-purger-ner images in the list.
Once the images are successfully loaded, start the Privacy Purger with the following command:
```
docker compose up -d
```
Use the command docker compose ps to monitor the container status. Ensure that the containers reach a healthy state before proceeding.
```
docker compose ps
```
To test the installation, open your web browser and navigate to the following URL to access the Privacy Purge Playground: http://<your-ip>:28080
tipp
To ensure that your application.yml is being loaded correctly, you can perform the following test:
Modify the application.yml: Locate the email entry in the regexPurger list and change the replacement value to <<EMAILTEST>>:
regexPurger: - id: email description: "Replaces email addresses by using RegEx" replacement: "<<EMAILTEST>>"
Restart the containers: Apply the changes by restarting the Docker containers:
docker compose restart
Test in the browser: Open the Privacy Purge Playground and process a text containing an email address.
Success: If the email address is replaced by <<EMAILTEST>>, the application.yml is loaded correctly.
Final step: Revert the changes in your application.yml and restart the containers once more to restore the original settings.
