US Patent Application: 20030120656
System, apparatus, and computer program for protecting personal
attributes information 

Abstract
Disclosed is a system for protecting personal attributes information
(PAI) to inhibit unauthorized use of personal information disclosed on
the network and protect the disclosed information. The system comprises:
a terminal apparatus including PAI managing means to generate and manage
customer's attributes information, and PAI protecting means to modify
changeable items of the customer's attributes information to be
transmitted to a destination across a network in such a manner as to
make different changes for different destinations; and a center
apparatus which offers services in a manner refined by using customer's
attributes information received from the terminal apparatus. Even if a
personal information leak occurred, defensive action can be taken
promptly by discarding the e-mail address disclosed to the information
leaker without changing the e-mail address in ordinary use. The
information leaker can be traced from the leaked e-mail address and
dealt with warningly afterward.
