A digital signature is much more powerful than a traditional paper-based signature. They provide you with a way to show a person signed a particular document at a particular time and helps to ensure that the document content has not been tampered with after it was signed. Additionally, the document version history shows recipients when a document was signed, and when changes were made. This revision history is encrypted and stored inside the PDF, and can be viewed in the Signatures pane.
To digitally sign a PDF document, you need a digital ID. To verify the signature of another person, you must first share your digital IDs and add each other to your Trusted Contacts list.
