ANONYMOUS MERCHANDISE PURCHASE SYSTEM FOR PURCHASING MERCHANDISE BY USER AUTHENTICATION USING MOBILE DEVICE HAVING INTERNET ACCESS FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide an anonymous merchandise purchase system which protects usefulness, safety, and users' privacy.

SOLUTION: A user accesses a shop site S from an arbitrary terminal P (PC terminal), wherein the user inputs only merchandise to be purchased and the mail address of his or her own browser phone B. The shop site informs an authentication server A of only the mail address and the amount of money for purchase of the merchandise. The authentication server issues an SID (session ID) and holds a pair of the SID and the mail address in a database DB and sends a purchase confirmation mail including the SID to the browser phone. When the user clicks a link in the mail, the individual discrimination number of the browser phone and the SID are safely transmitted to the authentication server. The authentication server checks the SID and the individual discrimination number by using the DB and then transmits a purchase completion message.
