Abstract
The present invention is directed to a system and method for secure document transmission. The method begins by receiving first and second key portions into a data storage associated with a document processing device. The first key portion suitably includes data representing a user of the document processing device and the second key portion suitably includes data representing a source of at least one electronic document directed for transmission to the document processing device. Next, at least one encrypted electronic document is received into the document processing device, wherein the document includes the second key portion. The received electronic document is then decrypted using the second key portion and the first key portion, which was retrieved from the data storage. Following decryption, a document processing operation is commenced on the decrypted electronic document.
