Information Technology (IT) started as a means to make scientists lives easier, doing only a handful of things at that time. Over the years, with the introduction and dominance of the Internet, IT has grown into a giant wave of innovation that curved the shape of the modern world. In the early '00s the majority of households in the developed world, owned a personal computer or a laptop with an internet connection, while scientists and experts started to seek for new ways to exploit the benefits of a rapidly evolving field. The first theoretical questions of a new direction had been posed much earlier. Why not use everyday appliances through Internet, why not wearing connected gadgets on us, why not connect everything? Internet of Things was born and the potentials it promised were astonishing. Mark Weiser in [34] pointed out that “There is more information available at our fingertips during a walk in the woods than any in computer system”. When smartphones were introduced to the market, it was only a matter of time, until every individual was connected to the Internet from anywhere at any time, even if he was on the move. Simultaneously, social media where born and the culture of open participation started to make an impact to modern society [19]. Users started to use mobile smartphone applications and to upload vast portions of information and data.
