ABSTRACT:
A communication system issues tokens in order to control communication received by the system. The tokens are arbitrary symbols which are stored in one or more Token Logs (TLs) for future reference. Those to whom the tokens are issued use specific tokens by including them in messages sent to the token issuer. The communication systems belonging to the potential token users record tokens which they have been issued, so that those tokens may be included in subsequent communication to the token issuers. Incoming messages without tokens are given a tokenless status and possibly rejected. Token-request tokens are automatically issued to allow other individuals to request tokens which can be used in subsequent communication. Multiple Token Logs are synchronized across multiple devices. Functional and informational message address headers are employed when sending messages so that tokens issued to a given user are not divulged to other message recipients who are different from the given user and different from the token issuer.
