Hi Soo-Hyun

Probably the simplest way would be to install encfs (from the repositories) 
and then cryptkeeper (a quick google will find it). They can then each setup 
an encrypted folder using cryptkeeper which is an applet. It's quite easy 
once setup with a few clicks to create the encrypted folder and each can then 
via cryptkeeper enable or disable their folder. Of course to log into their 
folder they will have to enter the password they supplied when the folder was 
created. Anyone trying to read their folder otherwise gets gibberish
