Abstract
An anonymous communication system allows a third party, which is not a communicating party, to determine the anonymities of the communicating parties. An anonymity notifying apparatus to be installed in an anonymous communication system enables anonymous communication. An anonymous communication system and method detects the anonymities of communication parties and notifies them to a third party device other than communication devices of the communication parties.
