Different types of points of users are converted to common points in a point conversion process. When a point data of a user is transmitted from an enterprise site where user points are individually managed to a common point site where user points are commonly managed, access from the enterprise site to the common point site is unidirectionally performed by permitting the transfer of data only from the enterprise site to the common point site. Thus, access to the enterprise site is not permitted. Since the unidirectional access from the enterprise site to the common point site is performed in point conversion, the connection destination of access from a user to a common point site is transferred to an enterprise site. The above-mentioned transfer of access enables point data to be transmitted to the common point site without access from the common point site to the enterprise site. <IMAGE>
