<p><P>PROBLEM TO BE SOLVED: To provide an electronic ticket distribution method or the like for an electronic ticket easy to visually recognize by a person similarly to a ticket of printed matter, capable of authenticating an individual. <P>SOLUTION: In this electronic ticket distribution method, a mobile terminal acquires bioinformation of a user, and transmits a ticket purchase message including the bioinformation to a server. The server generates a key from the bioinformation, embeds an authentication image in ticket information with a watermark by use of the key, and transmits the watermark ticket information to the terminal. The terminal generates the key from the bioinformation, detects the authentication image from the watermark ticket information by use of the key, and displays the bioinformation and the authentication image on a display. A code reading part of a ticket examination device is made to read the authentication image displayed on the display of the terminal, and genuineness/falseness of the electronic ticket is decided. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
