I use Adobe Acrobat Pro X on a Mac (10.6.8) and have created a form with two digital signatures. The form needs to be filled in by the employee at the top and digitally signed, then emailed to a supervisor for his/her signature. Is there a way to partially prohibit the text from changing in the upper portion (specific fields) above the employees signature after it's been signed by the employee but allow the supervisor to check a box and digitally sign the form too?
I don't think so, but the essence of digital signatures is that they sign the document AT THAT TIME. So any later change after someone has signed a document is discoverable and accountable.
Well... discoverable. Just because there are changes and a second signature doesn't mean that you can know who made those changes, only that they were made in the time between signatures.
Thanks. Your answer is more or less what I figured but it never hurts to ask those who know more!
