What is a Supercookie?

The term cookies has been used in the tech world for years to describe little bits of code intended to keep settings and login information consistent each time you visit a server you frequent. In some cases, cookies are used to track your activity and send usage reports to the site owner, and several browser scripts and extensions have been created to keep untrusted or unrecognized cookies from being used on your system. In some cases, cookies have been associated with malicious activities intended to track someone’s browsing history and get an idea of their interests, budget, and other personal data.


Getting rid of them isn’t terribly difficult, but you have to know where to go. As it turns out, Adobe has a page set up for this very purpose, but you can also access it by clicking on a Flash object and selecting the Settings option. In this panel, you can choose to Delete all sites, which will remove all of the Flash cookies present on your system.

Supercookies may sound like some impressive technology that can tackle your system and make it beg for mercy. While it may certainly be a concern for the privacy-minded individual, this form of tracking is nothing new. Perhaps this is just another reason why we should be considering more non-Flash Web scripts?
