\section{Introduction}
In our everyday life we are often exposed at articles, newspapers and media that argue about the possibility to sacrifice part of our privacy in favor of a \textbf{greater good}, the security of our society.\\
In this paper I don't want to state that I have the definitive solution to this problem, but that if we want to sacrifice our privacy we should do it in a conscious and informed manner, not in a subtle way like we are doing it now.\\
Indeed too often we give up a bit of our privacy simply by clicking the \textbf{agree} button on the \textit{terms of service} of a new application that we just downloaded on our smartphone. An example of how it could happen: we are just trying to download the newest and shiniest application to share moments of our life with our \textit{friends} and we are uncounsciously agreeing to give the rights to utilize or distribute those images to the provider of the application.\\
We may not think that this is in some way damaging our privacy, but as we shall see it is.
I also find particurlarly subtle that in some way we care about our privacy when the actor involved is a government or a public entity, but we too often don't think at the consequences of leaving in the hands of private companies and organizations rights over our data and informations.
