Abstract
The present invention is directed to a system and method for secure communication of electronic documents to a document processing device. A document processing request containing electronic document data is received containing document data in an unencrypted form. A seed value is then received and used to generate a random number. The random number is used to encrypt the electronic document. The seed value, in a header, is transmitted, along with the encrypted electronic document, to a document processing device. The document processing device extracts the seed value from the header and uses the seed value to generate a random number. The encrypted document is then decrypted using the random number generated from the seed value. The document processing device subsequently performs the selected document processing operation on the decrypted electronic document.
