ABSTRACT:
Sensor nodes (or addresses therefore), acting as real-time message decoys, are distributed across a real-time communications network to attract unsolicited real-time messages. Filtering rules are derived from the message characteristics (such as the source address) and messaging content of the traffic encountered at the sensor nodes. The filtering rules are distributed to filtering agents positioned in the communications network in such a way that they can filter traffic for legitimate users. The filtering agents may identify and control the disposition of real-time messaging traffic that is part of a mass communication campaign on behalf of legitimate users of the real-time messaging communication system. Disposition may include suppressing, diverting, or labeling.
