I am using a version of Ms Office of 2010, it was a beta version of public domain (I dont recall the name, but I believe it was called Blue version or something like that). I usually make my documents using the MS Word and then saving it like a pdf file using the function to publish as a pdf file within Word. The problem that I have is that some people are converting my documents into text, putting their name on it, and credited my work to them; so I would like to know if there is a way to:

• protect with a password the editing of my document
• protect it from converting into txt, with a password if its possible
• maybe but a digital signature in which it says my name as an author

I want that the people who access it can only read it, and nothing more.

I am using MS Word 2010 and Foxit Pdf (an old version), I usually do not use Adobe Acrobat.

Thanks
