PROBLEM TO BE SOLVED: To efficiently distribute contents by making summary data for trail viewing to be communicated voluntarily among user terminals. SOLUTION: When an information terminal of a contents transmitting side transmits contents (summary data for trial viewing) to an information terminal of the receiving side, the information terminal of the transmitting side updates the point value of a point-managing means, on the basis of contents management information. The point can be exchanged with the right for obtaining additional data, to make the summary data detailed data. That is, the contents are made to be distributed efficiently, by giving the point as an incentive to a user, who has copied the summary data for trial viewing and distributed the summary data to a third person. |
