US Patent 8103868 Sender identification system and method

A database is queried based upon data contained in a message to obtain sender identification information, at least part of which is not contained in the message as it was sent. The sender identification information is presented to a recipient, which can send a signal accepting or rejecting the message based upon the sender identification information. If an accept signal is entered, the message can be forwarded to the recipient and/or rendered to the recipient.
