The same data-collection revolution that has happened in the online world is about to repeat itself in the physical world because of the Internet of Things (IoT). The idea behind the IoT is that everyday items can now collect and transmit data wirelessly. The variety of objects that could be connected to the internet is practically endless—from the tiles on the pavement and the concrete in walls, to our shoes and clothes and even our toothbrushes. All are becoming connected, and all will soon begin adding their information to the cloud.
