Apparatus and method controlling use of individual segments of instant messaging content

Abstract

An apparatus and method is provided for a configuration of client work stations for instant messaging, wherein a participant intending to send a particular segment of chat content can elect to send the segment in an “off the record” mode. Content sent in this mode can be viewed but cannot be copied or saved by other instant messaging participants. The apparatus usefully includes a mode select device operable by the participant at a given station to designate each of a succession of chat content segments generated at the given station to be either for unrestricted use, or for off the record use, selectively. The apparatus further includes a component for applying a first use control message to each of the off the records segments sent from the given station to one or more of the other stations. A content control device located at a station receiving the off the record segments is responsive to the applied first use control messages to prevent the receiving station from retaining or otherwise propagating any of the received off the record segments.
