# Pseudoanonymization of Sensitive Data

You can prevent the collection of various pieces of information, including personally identifiable information (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

### User Name 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.

### Configure User Name Pseudoanonymization

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 one of these values. The default is **0** (Off).

> [!CAUTION]
> **WARNING**: If you enter **2**, SysTrack keeps no record of the original user names, so you can't map the collected data back to users. To keep that option, enter **3**.
  - **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 (for example, http://website.com)
- Full URL (for example, http://website.com/page1)
- Page title
- Load time
- Time spent on page and in focus
- Process ID (PID) of the browser tab or session
- Application invoking browser

### Website Details Options

Based on your preferences or legal requirements, you can:

- Disable all web tracking by turning off the plugin.
- Limit collection to a subset of URLs using the Web Tracking List.

### Configure Website Tracking

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 **Web Management**.
5. Configure tracking:
  - 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**.

## User Information and Active Directory Details

By default, SysTrack collects (see [Privacy](/documentation/docs/roles-privacy) in Roles):

- Local user information, such as full name, country code, and home directory.
- Organizational unit (Active Directory) details, including:
  - Location
  - Department
  - Active Directory manager
  - Description fields

### User Information Options

You can prevent the collection of local user information, Active Directory details, or both.

### Stop Collection of User Information

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 **Privacy**.
5. In the **User Collection** group, clear the following checkboxes:
  - **Collect Basic User Info** to disable collection of local user information.
  - **Collect Users Organizational Unit** to disable collection of Active Directory details.
6. Click **Save Changes**.

> [!NOTE]
> **NOTE**: Clearing Collect Users Organizational Unit stops SysTrack AI integrations from matching users to their systems. See [SysTrack AI Dependencies](/documentation/docs/roles-privacy#what-depends-on-these-settings) in Privacy
