Chatter is a term attributed to United States officials, by journalists, who explained that by monitoring the volume of the electronic communication, to or from suspected terrorists they can determine whether there is cause for alarm. They refer to the electronic communication as chatter.[1]
The term is not in common use among signals intelligence specialists, although the discipline of traffic analysis does consider changes in volume, senders, and known destinations.
Again according to journalists, even if they don't think they understand the real meaning of what suspected terrorists are saying to one another, they regard an increase in the number of the messages as a significant cause for alarm. Paradoxically, they also regard a decrease in the number of messages as a cause for alarm.[2]
