Anyone who can view the document can take a screen snap (clip) of your 
signature image and use it as they like. The security issue is more 
likely uncontrollable at the receivers end.
Are you suggesting something like a pass phrase required to open and 
view a document, you can do this by just encrypting the file and 
emailing with something like Enigmail.
