When modification information acquired by an acquisition unit indicates that content is a modification of other content, a computation unit calculates charge of the content by summing a charge of the other content and a price of the content and stores charge information indicating the calculated charge in a storage unit in correspondence to the content. When the modification information corresponding to used content indicates that the used content is a modification of other content, an addition unit adds a price of the other content to a distributed amount allocated to a creator who creates the other content. |
