What is a Cookie?

This article refers to the new EU regulations concerning Cookies

A cookie is a piece of data that is stored by a site within a browser. That same piece of data is then sent back to the same site by the browser. For instance, cookies are used to store log in information or to remember basket content when one leaves a site and returns later on. Cookies were created to help users navigate the Internet easily and quickly.

Even though cookies can’t carry viruses or install digital malware on the host computer, tracking cookies and particularly third-party tracking cookies are used to put together long-term record of users’ browsing histories. This is one of the major privacy concerns that has prompted US and European law makers to take action.

There are third-party cookies that are being set with different domains although just one is shown on the address bar.

For instance: When a visitor enters www.example1.com it sets a cookie with the domain ad.foxytracking.com. Later on, when the user visits www.example2.com another cookie is set with the same domain ad.foxytracking.com. In the end, both cookies will be sent to the advertiser who can then use them to create a browsing history of the user across all the websites from the advertiser’s portfolio.
