Who are you trying to protect the data from?
If it is from the system administrator or DBA, that is going to be tough.
If it is database users, you may be able to force access through views
that restrict visible tuples to those each user is supposed to be able to see.

I also have read some other tricks like indexing data by hashes, so that
if you know something about the data (perhaps a last name), you can
compute the hash and use that to retrive the related information.
