Supercookies

Supercookies represent an advanced tracking technology that is often more enduring and challenging to eliminate than standard cookies.

They raise considerable privacy issues, as they can monitor user activities with greater efficiency and persistence. This guide delves into the nature of supercookies, their operational mechanisms, the implications they carry, and strategies for safeguarding against them.

Understanding Supercookies: What You Need to Know

Supercookies, often referred to as "perma-cookies," are a type of tracking cookie that is stored in locations outside the conventional cookie storage areas, making them more challenging to remove.

In contrast to standard cookies, which can be easily deleted through browser settings, supercookies may reside at a deeper system level or within the browser's cache.

Essential Terminology Explained

• Supercookie : A more persistent tracking mechanism that is significantly more challenging to remove than standard cookies.

• Regular Cookie : A small data file stored by a web browser that retains user preferences and login credentials.

Understanding the Functionality of Supercookies

Supercookies can circumvent conventional cookie storage methods by embedding themselves in various components of the browser or the operating system.

They frequently utilize unique identifiers that remain intact even after standard cookies are cleared.

Effective Strategies Employed

1. ETags : Entity Tags, which are included in HTTP headers, can be utilized for user tracking purposes.
2. HTML5 Local Storage : Taking advantage of the local storage features offered by modern browsers to retain persistent data.
3. Flash Cookies : Using Adobe Flash to independently store tracking information outside of the browser environment.
4. Browser Fingerprinting : Generating a distinct fingerprint based on a user's browser settings and configurations.
