I created a pdf form that will be signed on location on a company machine. The form itself cannot be saved, but it has a custom save button on it that creates a new timestamped document with the information filled in. A company representative will open the form, hand a tablet to a user who then fills in all the fields and hits the save button, which then creates the doc in a secure folder. The problem is that.currently adobe automatically saves the last signature used, which means that the next user can easily sign with another users signature by accident unless the company rep manually clears all signatures every time. I need the signature to save on the document, but NOT be saved in acrobat, or at least be able to programmically clear all signatures when a user hits the forms custom save button.
When you sign PDF in Acrobat (X/XI) you can lock a signature. If the last signature is locked, Acrobat will not allow you or anyone else to sign this document again.
