A system for providing secure document distribution includes an application configured to: allow an author to create a document and secure the document using an access code, generate an image having the access code encoded in an encrypted format, forward a message to a recipient. The message includes the document and the image. A terminal configured to allow the recipient to open the message and a portable device configured to: allow the recipient to capture the image and to decrypt the access code embedded in the image, capture input information from the recipient, the input information to be used to ensure that the recipient is authorized to use the portable device, and generate an output including the access code. The terminal receives the output generated by the portable device and evaluates the output to determine if the recipient is allowed to access the document.
