The only way to stop copying is at the operating system level -- no MS or X 
Windows Clipboard, no screen shots, no copying of any data at all.  If the 
data can be copied in some close to clear-text form, it can be compromised. 
 Just look at how many commercial versions of UNIX now implement shadow 
password files.  If you want to protect the data, you have to completely 
protect the data.
