摘要

Distribution of contents through a network with reduced load on a server is enabled. Moreover, distribution with higher security is enabled. A server side connected to a predetermined network has a content database for managing data related to contents that can be distributed, a content cluster list containing data related to division of each content into clusters, and a cluster database related to an address where each cluster is stored. A device side that can be connected to the server saves at least a part of clusters of a received content by each cluster formed by dividing the content, and transfers a predetermined cluster saved by content saving processing to an indicated address in response to a request for transfer of a cluster of the received content.
