The snoop-proof laptop
http://www.theage.com.au/articles/2002/1
Most large organizations have a fleet of laptop computers. Most have medium, limited security for the data on these computers. Walk away from an operating laptop for a few moments and interlopers can help themselves, even if the computer has a cryptographic file system to keep sensitive information secure. That is because once the owner has supplied the initial decryption key, typically when logging in, anyone using the laptop has access to data stored on the disk. Brian Noble believes he has the answer to this.
The system requires laptop owners to wear a small device or token - in this case a wristwatch equipped with a processor and short-range wireless link to communicate with the laptop. When the token moves out of range, ZIA re-encrypts information on the laptop within five seconds, before someone else can gain access to it. When the laptop detects that the token has come back within range, the system decrypts the information within six seconds.
