Society has become increasingly interconnected during the last 30 years, since the birth of the World Wide Web in 1989. Along with it, wireless networks have become incredibly widespread all around the world, with billions of Wi-Fi or Bluetooth compatible devices that connect people with each other. The increasing diffusion of Internet of Things devices in the last decade has encouraged this phenomenon even more, at the point that, by now, we share many of our life details and activities online, for example our holiday photos or our evening running route on social networks. This also means that our actions may be remotely tracked by anyone who wants to, which opens new possibilities in lawful interceptions of suspects.
