I'm currently creating a form with signature fields that lock certain fields upon signing. The goal is to verify the identity of the person entering the data, and prevent tampering of previously entered data. I would like it so that they are unable to remove their own signature after they have signed for a set of results. It defeats the purpose of tracking I'm trying to achieve with this form if they could clear their signature and have someone else sign in their place (even worse yet, it removes the read only status allowing the results to be changed). Is there a way to remove right clicking on this field? Locking the signature field itself doesn't prevent this from being removed.
