Abstract
A data tracking unit 80 includes a distribution history storage unit 81 that stores a distribution history of data, a tracking tag adding unit 82 that adds a tracking tag used to identify tracking data, a first transmission unit 83 that transmits data to which the tracking tag is added to the component 90, and a distribution history registration unit 84 that registers a distribution history of the data to which the tracking tag is added, in the distribution history storage unit 81. The component 90 includes a second transmission unit 91 that transmits data to which the same tracking tag as a tracking tag added to the received data is added to another component 90 or the data tracking unit 80. The history registration unit 84 registers a result of tracking of data associated with the same tracking tag, as a distribution history of the data, in the distribution history storage unit 81.
