Abstract: Disclosed is a method and system for receiving and transmitting confidential documents and the like via facsimile machines. The system includes a security code-responsive, computer-controlled store and forward facility (SAFF) for receiving and transmitting documents between two remote facsimile machines. A security code is provided by the sender for each document transmission. The number does not identify a subscriber or a mailbox but identifies a fax message. Various degrees of security may be provided in sending a faxed document from a first location to a second location.
