Can I disable the ability to remove a digital signature from a for

[CSW]

I am trying to utilize digital signatures on my InfoPath forms. The
certificate was issued by Microsoft Certificate Authority. I attach the
digital signature to the document and no changes are allowed, but any user
can click on the digital signature -- the digital signature dialog box comes
us and they can remove the signature and make changes to the document. Can I
secure a document after it has been signed (maybe with the OnSign Event) so
that only the user that did the digital signature can pull up the document
and make changes?
