At each successive visit the cookies are sent back to the web site who created them (first-party cookies) or another site that recognize them (third-party cookies). The cookies are useful because allow a site to recognize the user device. They have different purposes like, for example, allowing navigating between pages efficiently, remembering favorite sites and, in general, improve the browsing experience. They also help to ensure that the advertising content displayed online is more targeted to the user and his interests. Depending on the function and purpose of use, cookies can be divided into technical, profiling and third-party cookies.

Note that by default most web browsers accept automatically all the cookies. Visitors / users can still change the default configuration.
As stated above, disabling or deleting cookies may preclude optimal use of some areas of the site or compromise the use of the services under authentication. Many of the cookies used are automatically deleted from the user’s computer hard disk at the end of each browsing session (from which the name “session cookie”). There are cookies that remain on the hard drive. Their stay is long enough (could be a few years) for reasons of greater convenience. After the first visit on the site, the system will be able to recognize in each subsequent visit that the user was already on that site and will therefore retrieved requests and favorite data of the user (long-term cookies). These cookies allow the user to not reenter his password or fill in forms at each new access. Cookies can also be turned off by selecting the corresponding parameters in the specific browser options. It should be noted, however, that in this way the user will not able to take full advantage of some features of the website.

In addition, cookies may be specific to the site (used, for example, to know the number of pages viewed within the site itself) or third-party (that are generated by other sites to deliver content on the site the user is visiting). This site may use third-party anonymous cookies to dynamically and, in an advanced mode, manage the delivery of advertisements. The most popular browsers provide the ability to block only third-party cookies, accepting only those specific to the site. In addition, some companies that create cookies on other sites offer the ability to disable and / or terminate in simple and immediate ways only their own cookies, even when they are anonymous or do not involve the registration of personal identification data (such as, for example, the IP address).

Cookies entered for aggregate analysis of site visits employs aggregated navigation data analysis tools that allow improving the web site: Google Analytics is a service from Google Inc. (“Google”). These tools use cookies that are stored on the User device in order to enable the manager of the web site to analyze how users use the site. The information generated by the cookie about the use of the web site by the user (including the IP address anonymized by removing some numbers) will be transmitted and stored on Google servers. This information is used for evaluating the use of the web site by the users, compiling reports on the activities of the website for the operators and provide other services relating to the website activity and internet usage. In order to fully protect user privacy, Alessandro Colla applies the ‘masking IP’, which requires the system darkening of the last octet of the user IP address before any processing, thus making the data analyzed anonymous. Users who do not want the cookies related to Google Analytics will be able to prevent the storage on their computers using the special “Browser Add-on for Google Analytics Opt” made available from Google at To activate the component, that inhibits the sending of information about the user visits, will be enough to install it by following the instructions on the screen, close and reopen the browser.
