Abstract
A system and method for preventing a copy of a document to the output from a printing node until the printing node authenticates the intended recipient. The system includes a sending node, a printing node and a communication link coupling these nodes together in a network fashion. The sending node has access to a public key of the printing node and uses this public key to encrypt a header and document before transmission to the printing node over the communication link. The priority node has access to its private key to decrypt the header to ascertain whether the document requires authentication by the intended recipient before being output.
