摘要：
A first copier acquires data and determines a plurality of recipients to deliver split data. A data splitter 308 splits data into a plurality of data blocks and a dummy data generator 315 generates dummy data. A data delivery unit 310 delivers the data blocks and dummy data to the plurality of recipients. At the same time, the data delivery unit 310 outputs restoration information including information about the recipients of the data. Based on the restoration information, a second copier collects the plurality of data blocks and the dummy data from the plurality of recipients and discards the dummy data, acquiring the plurality of data blocks. The second copier reconstructs a set of data from the plurality of data blocks.
