Augmented reality glasses could be compromised by a hacker who would be able to see and hear everything the wearer does.
Google Glass, the wearable computer being developed by the search giant, might be a threat to its owners' privacy because it has no PIN or authentication system, hackers have discovered.
Jay Freeman, a Santa Barbara-based programmer who specialises in cracking smartphone security for both iPhone and Android devices, discovered that Glass has a "root" capability which can be enabled by attaching it to a desktop computer and running some commands.
That would then give a hacker the ability to take control of the Glass's output – meaning a hacker could monitor everything the owner was doing from a smartphone in their pocket.
