What are the best practices for tracking user activity while ensuring privacy and security?

To track user activity while ensuring privacy and security, it is important to anonymize personal data, secure data transmission, and obtain user consent for tracking. One way to achieve this is by using pseudonymous identifiers instead of directly identifying users in tracking data. 

<?php
// Generate a pseudonymous identifier for the user
$user_id = md5($_SERVER['REMOTE_ADDR'] . $_SERVER['HTTP_USER_AGENT']);

// Track user activity with the pseudonymous identifier
track_user_activity($user_id, 'page_view');

function track_user_activity($user_id, $activity) {
    // Implement tracking logic here, such as storing the activity in a database
}
?>
