Local files don't work that way, not anywhere I've ever been.
You could change their ownership to a different user and prevent others from reading them. When they try and open them they'll get "permission denied". To get into them they'd need to su into that user.
You could also install truecrypt and make a volume with it, not truly a directory, it'd be a program they have to run to get into it.
