# Pseudoanonymization of Sensitive Data

You can prevent the collection of various pieces of information, including PII and personal data, by the SysTrack agent. SysTrack uses the term pseudoanonymization for this capability, also written as pseudonymization.

This document explains how to configure pseudoanonymization in SysTrack to protect the following sensitive information:

- User Names
- Website Details
- User Information and Active Directory Details

## User Names

### Pseudoanonymization Options

SysTrack supports three pseudoanonymization options for user names:

- Replace user name with Terminal ID.
- Replace user name with MD5 hash (no lookup). This is irreversible.
- Replace user name with MD5 hash (with lookup). Allows mapping back to the original username if needed.

### Configuration

1. Go to **Configure > Roles**.
2. Click the lock icon in the upper-right corner to obtain the Configure lock.
3. Select the role.
4. From the **Additional Settings** list, select **Application Management**.
5. In the **Replace user name** field, enter:
  - **1** for Terminal ID
  - **2** for MD5 hash (no lookup)
  - **3** for MD5 hash (with lookup)
6. Click **Save Changes**.

> [!NOTE]
> **NOTE:** Make sure this role is included within the configuration assigned to the endpoints that need the pseudoanonymization.

The screenshot shows the option for MD5 hash with no lookup selected:

As a result, usernames are replaced with an MD5 value:

## Website Details

By default, SysTrack collects (see [Web Data Collection](/documentation/docs/web-data-collection)):

- User site visits
- Base site URL (e.g., http://website.com)
- Full URL (e.g., http://website.com/page1)
- Page title
- Load time
- Time spent on page and in focus
- PID of browser tab/session
- Application invoking browser

  - To disable all tracking, clear all checkboxes and remove URLs.
  - To limit tracking, specify allowed URLs in the **Web Tracking List**. For details, see [Web Management](/documentation/docs/web-data-collection-systrack-browser-extension).
6. Click **Save Changes**.
