PROBLEM TO BE SOLVED: To safely and economically manage user personal information necessary for communication between a user terminal device U and a net store device S by managing user personal information in a batch.;SOLUTION: In an on-line shopping system, user personal information is managed in a batch by a user management center device TTP. This center device TTP issues temporary information TU including temporary user information and temporary authentication information in response to log-in from the user terminal device U to a designated net store device S, and distributes the TU information to the user terminal device U and the designated net store device S. Thus, when the user terminal device U requests the net store device S to perform authentication on the basis of the TU information, it is possible for the net store device S to authenticate the user terminal device U on the basis of the TU information from a user management device TTP. In this case, user personal information can be prevented from being leaked to the net store terminal S, and it is not necessary for each net store device S to manage user personal information.;COPYRIGHT: (C)2006,JPO&NCIPI
