Abstract

The subject application is directed to securely communicating electronic documents to an associated document processing device. User identification data inclusive of a user credential is received from a user with a document processing request having one or more electronic documents. Page job language information is generated for output of the request by a document processing device. A seed value is received in accordance with the user credential and used to generate a random number. Each document is encrypted using the random number. The encrypted data and page language information are communicated to the document processing device and stored in association with user identification. Upon receipt of user login data a listing of requests is displayed. The seed value is retrieved from user credentials for generation of a random number. Selected electronic documents are decrypted via the random number and output in accordance with the associated page job language information.
