Abstract

A content delivering system allows easy acquisition of content upon personal authentication. A personal computer (7) issues a content acquisition request. In response to the request, a mail delivery server (15) transmits an address of a pay site to the personal computer. A cellular phone (11) is used to access the pay site address and enter an ID number and a password for conducting registration and making a content using contract at the pay site. After the registration, the pay site prepares a personal authentication program corresponding to the ID number and password. The cellular phone is used to download the personal authentication program. If personal authentication is successfully conducted according to the personal authentication program, a content server (5) allows the personal computer 7 to acquire content. An accounting server (17) accumulates charges according to content acquired by the personal computer. The accumulated charges are equal to content charges minus commissions including a personal authentication commission.
