Hacked dog, a car that snoops on you and a fridge full of adverts: the perils of the internet of things

In the not so distant future, every object in your life will be online and talking to one another. It'll transform the way we live and work - but will the benefits outweigh the dangers?

If we think of today's internet metaphorically as about the size of a golf ball, tomorrow's will be the size of the sun. Within the coming years, not only will every computer, phone and tablet be online, but so too will every car, house, dog, bridge, tunnel, cup, clock, watch, pacemaker, cow, streetlight, bridge, tunnel, pipeline, toy and soda can. Though in 2013 there were only 13bn online devices, Cisco Systems has estimated that by 2020 there will be 50bn things connected to the internet, with room for exponential growth thereafter. As all of these devices come online and begin sharing data, they will bring with them massive improvements in logistics, employee efficiency, energy consumption, customer service and personal productivity.

This is the promise of the internet of things (IoT), a rapidly emerging new paradigm of computing that, when it takes off, may very well change the world we live in forever.
