Abstract
A Tokenized Communication Service Provider (TCSP) for providing secure messaging between a consumer and a message sender without exposing the consumer communication preferences and Personally Identifiable Information (PII) to the message sender. TCSP issues a communication token to be used for the communication between the consumer and the message sender. Consumer authorization is recorded in a blockchain ledger and a Zero Knowledge Proof mechanism is used to establish that the TCSP possesses the consumer contact information and authorization. The consumer authorization is revocable by the consumer, and the revocation is recorded in the blockchain ledger.
