<P>PROBLEM TO BE SOLVED: To solve the problem that when delivery of purchased digital content fails, it is required to input purchaser information again for retrying a purchase process or to check purchase records for preventing duplicate payment while there are limitations on the number of delivery retries and a repurchase period. <P>SOLUTION: A digital content delivery method generates a digital content personal use condition on the basis of a digital content use condition 104 and gives the digital content personal use condition to a purchaser when an electronic mall server 110 sales digital content 101. As for repurchase when the delivery of the digital content 101 fails, if the digital content personal use condition given when the digital content 101 is purchased is valid, the digital content 101 is redelivered without collecting a digital content value 103 again. <P>COPYRIGHT: (C)2009,JPO&INPIT |
