Subject: Security Issue  

Is it possible to recover information from an undo datafile? I have been searching for information on securing oracle datafiles and see that there are .dbf file viewers that claim to be able to view/edit/export the contents as text. I am thinking that its not likely to be possible to reconstruct anything usable from an undo datafile.

I know that Oracle 10G has the ability to encrypt the contents of datafiles and store the key in a wallet. We are planning an upgrade in a year but right now I'm having to answer questions about vulnerabilty of backups stored on removable media.
