Hans - I cannot attest to just how secure it is, but Adobe Acrobat 4.0 and up (I have 5.0) supports digital signatures and will not allow modification of the document, other than applying other (or new) signatures, without a password (once set).
I've received a number of document forms in Adobe Acrobat format that have certain input fields secured, with others not secured, allowing input of needed information. Regards, Peter L.
