The disclosed embodiments relate to creation and dissemination of unique identifiers, i.e. tokens, for use in communication of messages from a transaction processing system, to participants therein whereby messages, or at least a portion of the content thereof, indicative of a response to a request, to transact or modify a prior transaction, are consolidated, or otherwise combined, with the corresponding directed reporting messages communicated to the particular participants participating in the reported transaction while preserving the anonymity of those participants to which messages are particularly directed. The identifiers are structured so as to facilitate rapid validation and dissemination while eliminating the ability to associate any given identifier, or set thereof, with a participant.
