<P>PROBLEM TO BE SOLVED: To solve the problem that although there is a great demand to provide a limited coupon and a content giving a privilege of a store or service to only a specific member having relationship with a local account, called a follower, a fan, etc., of a store or commercial service on social media such as Twitter and Facebook, easy means of probing whether a user is the specific member at the store and allowing a shop clerk to make a determination is not available, and a coupon which is displayed even to a user other than the specific member has a large risk of impersonation. <P>SOLUTION: There is provided a system which acquires registration information on a user from the social media, and displays the coupon only when conditions are met, the system being capable of proving and determining whether a user is a specific member only by presentation of the coupon. Further, the risk of impersonation is reduced through user authentication, and computer-assisted name identification of a store visitor and a user of the social media becomes possible with an access log. <P>COPYRIGHT: (C)2013,JPO&INPIT |
