This page covers what a digital signature is, how to apply one within EPR, and how EPR (and Scout specifically) interact with existing digital signatures within submitted files.

Overview

A digital signature is a mathematical technique used to validate the authenticity and integrity of document. It's the digital equivalent of a handwritten signature or stamped seal, but it offers far more inherent security. A digital signature is intended to solve the problem of tampering and impersonation of electronic document. Digital signatures can provide evidence of origin, identity and status of electronic documents, transactions or digital messages. Signers can also use them to acknowledge informed consent. 

In many countries, including the United States, digital signatures are considered legally binding in the same way as traditional handwritten document signatures.

Pre-requisite

When you receive a digitally signed document, both Adobe Reader and Acrobat ask three key questions to validate the signature:

1. Is the digital certificate that signed the document still valid? Has it expired or been revoked?
2. Has the document been changed since it was signed? Has the integrity of the document been affected? If there are changes, are they allowed changes or not?
3. Finally, does this certificate chain up to a certificate listed in the Trusted Identity list? If so, the signature will be trusted automatically.

   2. Click the Tools tab and scroll down to the Forms and Certificates section and select Certificates.
      
   3. Click on Digitally Sign from the options bar at the top.
      
   4. Select the digital signature you want to use and click Continue. If you have not yet added a digital signature certificate to Adobe Acrobat, select Configure New Digital ID and follow How to create a Digital ID.
   5. Configure the appearance of the signature and select Sign.

Applying a Digital Signature in EPR

Digital signatures can be applied directly within EPR when manually preparing deliverable documents, if desired.
