We can’t avoid that smartphones, tablets and wearable devices collecting our data. Smartphones are able to track everything from search queries on google, to usage times and preferences when it comes to social contacts. The whole economy of devices connected to the internet is called the Internet of Things, short IoT. Estimates suggest that by 2020 over 200 billion devices will be connected to the IoT. The market size is estimated to be $3 to $7 billion (peppet, p5). As time goes on, we are getting more and more connected to the internet, which just opens more channels that companies can gather our data. Only few users are aware what actually happens with this data though.
