The present invention provides an on-car-data recording apparatus 2 mounted on a train to record image data, which is data of a video or an image photographed by an image pickup apparatus set in the train. The on-car-data recording apparatus 2 includes a secret-key retaining unit 22 that retains a secret key paired with a public key for electronic signature for which certification by a certification authority is completed, a train-specific-information managing unit 23 that manages information specific to the own train capable of specifying a traveling position of the own train, an electronic-signature generating unit 25 that integrates, every time the image data is generated by the image pickup apparatus, the image data and the information managed by the train-specific-information managing unit 23, calculates a hash value of obtained integrated data, and generates an electronic signature on the basis of the calculated hash value and the secret key, and a image data managing unit 24 that retains the generated electronic signature and the image data used in generating the electronic signature in association with each other.
