Abstract:
A communications terminal (a first communications terminal) that creates a holding list that lists information about remaining data, after the removal from data held by said communications terminal of at least one item of data which is not desired to be shared with another communications terminal (a second communications terminal), and sends said list to the second communications terminal by using a communications message. The second communications terminal determines what data, among the data in the holding list received from the first communications terminal, is not held by the second communications terminal, and sends a request for the determined data to the first communications terminal by using a communications message. The first communications terminal sends the data requested by the second communications terminal to the second communications terminal, by using a communications message.
