1) Text
It is a feature of Acrobat reader that you can take any pdf file and select text
from it and copy this to a clipboard. The only way to prevent this is to use a
version of Acrobat reader before 4.0! You should not be able to alter the text
using acrobat reader (although using the full version of Acrobat, you should be
able to 'touch up' any text that you feel like).

2) Adding Graphics
Like 1), you will not be able to prevent anyone fom drawing on your document,
however to prevent it from being saved, just set the read-only attribute to 'on'
when you create the pdf file. (The user can of course turn this off it they
download the file locally, but that's up to them!)
