How to prevent data in an excel file from being copied, printed or duplicated?

I have a huge Excel file that contains very important imformation, I wan't to allow other people to view it, but not be able to copy/paste any data from it, print the file or copy the actual, physical file (not sure if possible through Excel but there must be a way to do this somehow). I'm wondering if these things are possible and if so how to go about doing them and would greatly appreciate anyones help.
