Abstract

A communication device provides data to a data acquiring node based on a consensus of a plurality of participating nodes. The communication device includes a processor. The processor divides the data into N data components. N is an integer equal to or larger than two. When the N data components are stored in different storage areas, the processor encrypts addresses of storage areas in which the data components are respectively stored with respective public keys of N participating nodes among the plurality of participating nodes. The processor transmits access right information that indicates the data acquiring node has a right to access the data and the encrypted N addresses to the plurality of participating nodes.
