US Patent 8190878 Implementation of private messaging

A method is disclosed for sending messages such as emails where the sender and receiver in the exchange remain anonymous to each other. The method uses a service, which may for example be an Internet service provider, which acts as an intermediary between a first party and second party to a message. All exchanges between the first and second parties pass through the service, which masks all true identities while ensuring that the message is routed to the proper recipient(s).
