Abstract

The present invention addresses the problem of realizing safer and more efficient information processing in an information processing system for transmitting data.　This information processing system comprises: a first type electronic device having at least a transmission function for transmitting transmission data; and a plurality of second type electronic devices each having at least a reception function for receiving the transmission data and each including a storage medium for storing the transmission data. The first type electronic device includes target data acquisition processing means for generating transmission target data. Each of one or more second type electronic devices for storing the transmission data among the plurality of second type electronic devices is set as a storage target second type electronic device. When storing the transmission data in a recording device group arranged outside, the storage target second type electronic device executes control for storing the transmission data in the recording device group on condition that it is confirmed that all of latest hash values stored in the one or more storage target second type electronic devices including said storage target second type electronic device match.
