Information on Cookies
What is a cookie?
Cookies are small text strings that the sites visited by the user send to his terminal (usually the browser), where they are stored before being re-transmitted to the same sites at the next visit by the same user. While browsing a site, the user can also receive cookies on his terminal that are sent from different sites or web servers (so-called “third parties”), on which some elements may reside (such as, for example, images, maps, sounds, specific links to pages of other domains) present on the site that the same is visiting.
Cookies, usually present in users’ browsers in very large numbers and sometimes even with characteristics of wide temporal persistence, are used for different purposes: execution of computer authentication, session monitoring, storage of information on specific configurations concerning users who access the server, etc.
In this regard, two macro-categories are therefore identified: “technical” cookies and “profiling” cookies.
THE 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 this service” .
They are not used for other purposes and are normally installed directly by the owner or manager of the website. They can be divided into navigation or session cookies, which guarantee the normal navigation and use of the website (allowing, for example, to make a purchase or authenticate to access restricted areas); analytics cookies, similar to technical cookies when used directly by the site manager to collect information, in aggregate form, on the number of users and how they visit the site; functionality cookies, which allow the user to browse according to a series of selected criteria (for example, the language, the products selected for purchase) in order to improve the service provided.
THE profiling cookies they are aimed at creating profiles relating to the user and are used in order to send advertising messages in line with the preferences expressed by the user while surfing the net. Due to the particular invasiveness that such devices may have in the private sphere of users, European and Italian legislation provides that the user must be adequately informed on the use of the same and thus express their valid consent.
