Abstract
This patent provides technology by which the risk of data destruction during data transmission can be further reduced. On the basis of sensor information, a data block generation unit 32g generates a data block BD1, a data block BD2, and a data block BD3. A first processing unit 33g generates second association information FT1, and appends the same to the data block BD2 as first association information HD2. A second processing unit 34g generates second association information FT2 including at least a hash value obtained from the data block BD2, and appends the same to the data block BD2. A storage control unit 36g executes control whereby the data block BD2, to which the first association information HD2 and the second association information FT2 have been appended, is correlated to at least one other unit of data, including the data block BD1, by using blockchain technology, and stores the same in a storage unit 12g. The abovementioned problem is thus solved.
