<P>PROBLEM TO BE SOLVED: To provide a system for authenticating member identification information to accumulate points using a network type information terminal, such as, a mobile terminal and to provide a means for safe management of customer information in that case. <P>SOLUTION: Authentication with authentication information of a database is performed on the information terminal which made a request for ID issuance. When authentication is established, a variable-type mathematical expression using time for variable, or a random number is used for the request for ID issuance to generate an ID. The generated ID is converted into an electronic image and is transmitted to the information terminal. Membership information stored in the database is provided, when detecting the coincidence between the generated ID and the ID, obtained by decoding the electronic image transmitted from the information terminal. <P>COPYRIGHT: (C)2009,JPO&INPIT |
