What is a cookie?
Cookies are small text strings that the sites you visit send to your terminal (usually your browser), where they are stored and then sent back to the same sites the next time you visit the same user. While browsing a site, the user may also receive cookies on his terminal that are sent by different sites or web servers (so-called “third parties”), on which may reside certain elements (such as, for example, images, maps, sounds, specific links to pages of other domains) on the site that he is visiting.
Cookies, usually present in users’ browsers in very large numbers and sometimes with characteristics of wide temporal persistence, are used for different purposes: execution of computer authentication, monitoring of sessions, storage of information on specific configurations regarding users accessing the server, etc..
In this respect, two macro-categories are identified: “technical” and “profiling” cookies.
Technical cookies are those used for the sole purpose of ‘carrying out the transmission of a communication over an electronic communications network, or to the extent strictly necessary for the provider of an information society service explicitly requested by the subscriber or user to provide that service’.
They are not used for any other purpose and are normally installed directly by the owner or operator of the website. They can be divided into navigation or session cookies, which ensure normal navigation and use of the website (allowing, for example, to make a purchase or authenticate to access restricted areas), cookie analytics, similar to technical cookies when used directly by the operator of the site to collect information, in aggregate form, on the number of users and how they visit the site itself, functionality cookies, which allow the user to navigate according to a series of criteria selected (for example, language, products selected for purchase) in order to improve the service provided to the same.
Profile cookies are designed to create user profiles and are used to send advertising messages in line with the preferences expressed by the user when surfing the web. Due to the particular invasiveness that these devices may have in the private sphere of users, the European and Italian legislation requires that the user must be adequately informed about the use of the same and thus express their valid consent.
