The Everdream corporation (http://www.everdream.com) has released a
service which will encrypt or delete files on a laptop or PC if stolen.
The software runs as an agent on the computer–this connects to the
control centre of Everdream which extracts network location details from
the computer and if the computer is stolen will either encrypt or delete
files specified by the customer. A policy is created by the customer to
decide whether encryption or deletion would take place, and which files
The service costs around $6 per PC.
The usefulness of such a system is debatable, it assumes that the thief
is stupid enough to connect to the internet. Most stolen computers will
be reformatted as soon as they are switched on; windows logon passwords
will prompt this. If the computer was stolen for the information
contained on the hard disk, it’s unlikely that it would be connected to
the internet before all of the desired information has been pulled off.
