Wipe or Kill Your Laptop, On or Off, if Stolen

Laptops and small computing devices get stolen on a daily basis. People traveling through airport terminals on a frequent basis know this very well. Your data is at risk when you're mobile.

Suffice to say, losing your laptop is the least of your worries. Sure, if you've plunked a couple of grand into a laptop, it hurts to find out that it's lost or stolen. But the worst part of the situation is the lost of your data. Businesses value their employees data more so than the hardware. Even on a personal scale, losing your laptop could mean losing very precious information and data that you have accumulated over a long period of time.

Not to worry. Fujitsu today announced that it has developed an always-on security chip for laptops that can lock down the data on a laptop's hard drive remotely, even if the unit is turned off. Not only this, the lost or stolen laptop can even be completely disabled, preventing it from being turned on in severe instances.

Using technology from Willcom Inc., Fujitsu plans to roll out the new security feature starting in Q3'09. The technology will roll out in Japan first, using Willcom's PHS network, which can accept remote commands.

The technology works by utilizing an active chip that handles strong encryption to the hard drive. The encryption key is stored on the chip itself. A user that has lost their laptop can remotely issue a wipe command, for example from a cell phone, and the chip will instantly delete the key. This, Fujitsu says, will render the hard drive completely useless. The user can even lock the PC remotely, preventing it from being turned on.

According to Fujitsu:

The communications module remains in standby mode even when the PC is switched off, allowing for lock and delete commands to be executed regardless of whether the PC is on or off. This is the first such technology in the world. Because the module communicates over the inherently low-power PHS network, battery drain is minimal, so it can remain in standby mode for long periods of time. Customers can view command results in detail on a control server.
