Abstract
A sending part sends a data generated by a second device from the second device to a first device. A data collating part collates the data sent from the sending part with a data generated by the first device, and determines that it is abnormal when a mismatch between these data occurs. Thus, a data generated by the first device is collated with a data generated by the second device and when a mismatch between these data occurs, it is determined that it is abnormal, so that abnormality can be detected surely.
