Electronic mail distribution network implementation for safeguarding sender's address book covering addressee aliases with minimum interference with normal electronic mail transmission
First Claim
1. In a communication network for electronic mail distribution between data processor controlled interactive display terminals, a sending terminal comprising:
- means for storing unencrypted data representative of a plurality of aliases for a plurality of addressees of electronic mail;
means for separately storing encrypted data representative of electronic mail addresses of said plurality of addressees;
means for prompting a sender of electronic mail to enter addressee data;
means for determining from said unencrypted data whether said entered addressee data includes one of said aliases; and
means for requiring entry of a key to decrypt the encrypted data to thereby provide the address of the addressee having said alias, responsive to a determination that said entered addressee data includes one of said aliases.

Abstract
The E-mail sender'"'"'s address book is safeguarded from computer virus intrusion with only minimal interference with normal E-mail distribution from the sender. Complete encryption of the address book create interference with the send function in that before any E-mail function may be started, the address book must be accessed and decrypted even when the E-mail being sent does involve the address book. However, the address book may be safeguarded from the computer virus with minimum E-mail interference if only a part of the address book is encrypted. There is stored the unencrypted data representative of a plurality of aliases for plurality of addressees of electronic mail, and separately stored encrypted data representative of the electronic mail addresses of said plurality of addressees. In response to a request to send electronic mail to one of said aliases, the entry of the key to decrypt the encrypted data is required to thereby provide the address of the addressee having said alias. If no alias is entered, i.e. the full address is entered, then the E-mail is sent without requiring a key entry by the sender.
