Clearing a signature on a pdf form

[Guest]

I use pdf forms and a digital signature with password protection on the signature.  I have the forms setup so once they are signed they are locked and the form fields can no longer be edited.  That is working great, but I can see in the latest versions of adobe (maybe some versions too) I am able to right click on the signature, click 'Clear signature' which then allows me to edit the form and resign it.

This is an issue for me, as I don't want the form to be edited once it has been signed.  Is there any way to change this?  Im guessing it is a feature of adobe and I am stuck with it, but it just doesn't seem right that I can sign a form, clear my signature, edit the form and re-sign it so easily.

Note that it's only you who can clear it, not someone else. It's really no different than if you were to reopen the original form, filling it in and signing, and then deleting the first signed document. Kind of like tearing up a hand-signed paper form and starting again with a blank copy, it 's just more convenient.
