“The internet of things” is one of the buzziest bits of jargon around in consumer electronics. The idea is to put computers in all kinds of products — televisions, washing machines, thermostats, refrigerators — that have not, traditionally, been computerised, and then connect those products to the internet.If you are in marketing, this is a great idea. Being able to browse the internet from your television, switch on your washing machine from the office or have your fridge e-mail you to say that you are running out of orange juice is a good way to sell more televisions, washing machines and fridges. If you are a computer-security researcher, though, it is a little worrying. For, as owners of desktop computers are all too aware, the internet is a two-way street. Once a device is online, people other than its owners may be able to connect to it and persuade it to do their bidding.
