Actually I'm trying to prevent certain files from leaving the computer,
specifically source code. However, that means I need to watch for file
copies, renames, cut and pastes, emails, etc. The idea was to encapsulate
the actual file data in an encrypted wrapper that would have to be
opened/decrypted by our program. The wrapper would also contain the
allowed operations on the file data itself, which is where auditing would
come in so that we can see what the user is attempting to do with the
file. After we decrypt the file and remove the wrapper, the raw data would
be opened in the appropriate application on the system (e.g.
OpenOffice.org). However, at the save we would want to add that wrapper
back in so they could not simply circumvent the wrapper protection. Of
course, we don't want to have to modify any of the user level applications
to achieve this functionality.

Thanks
