Abstract: A data storage apparatus, including: encoding part; and falsification correction part; wherein the encoding part includes code generation section that generates, based on original data and falsification frequency, a code which enables correction of the original data, and includes a tag generation section that generates a first tag which enables detection of falsification of the original data, based on the original data; wherein the encoding part stores the code and the first tag in a storage part; and wherein the falsification correction part includes a falsified portion determination section that retrieves a falsified code and the first tag from the storage part, generates a second tag based on the falsified code, and determines a falsified portion(s) in the falsified code by using the first tag and the second tag, and includes a data correction section that outputs corrected original data by using the determined falsified portion(s) and the falsified code.
