摘要

A disclosed measuring device generates measurement data recorded by continuously measuring measurement information. Divided data items are generated by dividing the measurement data. A feature quantity representing each of the divided data items generated is acquired. A time stamp is acquired based on measurement time data, where the measurement time data include the feature quantities and measurement time identification information of each of the divided data items, the measurement time identification information expressing a measurement time of each of the divided data items on a predetermined time axis. An electronic signature is generated for the measurement time data and the time stamp by using a private key specific to the measuring device. The measurement time data, the time stamp, and the electronic signature are saved in association with the measurement data.
