Abstract

A ticket issuer server for receiving purchase requests for contents transmits a ticket, storing a charges receiving entity identifier as contents charges information and data of distribution charges with regard to the charges receiving entity, to a user device, under the condition that billing processing for the contents purchase request of the user device has ended, and executes cashing processing based on receipt of the ticket from the user device. Also, contents purchase log data is collected according to updating processing of a public key certificate of the user device which purchases contents, and further, between entities executing data communication, attributes information is obtained from a public key certificate or attributes certificate of the entity which is the other party of communication, and attributes confirmation based on the obtained attributes information is performed, so processing in guise of another entity can be prevented.

Description

technical field [0001] The present invention relates to a content distribution system and a content distribution method. More specifically, the present invention relates to a content distribution system and a content distribution method in which, in a content transaction between an entity performing a content providing service and a user device receiving the content, transfer to a license can be performed reliably and efficiently. Settlement processing of content fees paid by managers and content copyright holders, in which the actual content transactions can be reliably and efficiently accurately understood in content transactions between an entity performing content providing services and a user device receiving content, and in which By performing attribute confirmation of another communicating party between entities performing data communication, data communication processing such as content distribution processing can be performed safely and legally.
