Securing financial data

Home users have a few choices for good security for their financial data (on the assumption that their computer or data will eventually fall into the hands of a thief). One solution is to do the same types of things suggested by this thread in /., even if it is written for something else. Then there is Linux encrypted filesystems, including eCryptFS. Of course, I'll probably want to upgrade first because there have been some decent changes in the year since I installed 8.04. Someday I'll have some time to get that set up.
