Supercookies

Persistent tracking mechanisms present significant challenges to online privacy. Unlike regular cookies, which can be easily managed and deleted through browser settings, these tracking mechanisms are stored in less obvious locations, making them more difficult to detect and remove. This article explores what these mechanisms are, their functionality, the implications they have on user privacy, and the steps users can take to safeguard themselves.

What Are Tracking Mechanisms?

Persistent tracking mechanisms are advanced tracking methods that are much more persistent and challenging to delete compared to regular cookies. While regular cookies reside in the browser’s cookie storage and can be deleted with just a few clicks, these mechanisms are often embedded deeper within the system or in the browser’s cache. This complexity allows them to track user behavior consistently, across different sessions and browsers.

Key Definitions:

• Persistent Tracking Mechanism: A tracking technology that remains active and is harder to eliminate than regular cookies.
• Regular Cookie: A small data file stored by a web browser that retains user preferences and login credentials.

How Do Tracking Mechanisms Work?

These tracking techniques evade standard cookie storage by embedding themselves in various parts of the browser or operating system. They frequently utilize unique identifiers, allowing them to remain intact even after regular cookies are cleared. Some common methods deployed include:

1. ETags: These entity tags found in HTTP headers can be reused for user tracking.
2. HTML5 Local Storage: This takes advantage of local storage features in modern browsers to maintain persistent data.
3. Flash Cookies: These utilize Adobe Flash to save tracking data independently from the browser itself.
4. Browser Fingerprinting: This technique creates a unique fingerprint based on the user’s browser settings and configurations.
   For more information on browser fingerprinting, visit Browser fingerprinting refers to the technique used to collect various information about a user’s browser and device configuration. This data can include details such as the browser type, operating system, installed plugins, timezone, and screen resolution. By combining these unique attributes, websites can create a distinct profile or “fingerprint” for each user, which can be used for tracking purposes or to enhance security measures..
