What are the ethical implications of attempting to access personal information on a user's PC without their knowledge or consent?

Attempting to access personal information on a user's PC without their knowledge or consent is a violation of privacy and can lead to ethical concerns. It is important to always obtain explicit consent from the user before accessing any personal information on their device.

// Check if user has given consent before accessing personal information
if ($user->hasGivenConsent()) {
    // Access personal information
    $personalInfo = $user->getPersonalInfo();
} else {
    // Notify user that consent is required to access personal information
    echo "Please give consent to access personal information.";
}
