Spies will no longer have to plant bugs in your home - the rise of 'connected' gadgets controlled by apps will mean that people 'bug' their own homes, says CIA director David Petraeus.
The CIA claims it will be able to 'read' these devices via the internet - and perhaps even via radio waves from outside the home.
Petraeus says that web-connected gadgets will 'transform' the art of spying - allowing spies to monitor people automatically without planting bugs, breaking and entering or even donning a tuxedo to infiltrate a dinner party.
Privacy groups such as the Electronic Frontier Foundation have warned of how information such as geolocation data can be misused - but as more and more devices connect, it's clear that opportunities for surveillance will multiply.
