Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To output an electronic certificate specific to a camera device in addition to video data obtained by the camera device to a verification device, and thereby to allow the verification device to easily detect malicious replacement during a movement process of the electronic certificate obtained together with the video data.SOLUTION: In a video data verification system 5, a monitoring camera 10 includes an imaging unit 26 for photographing an imaging area. The monitoring camera 10 stores an M2M certificate 101 generated by an intermediate CA 60 and video data obtained by the monitoring camera 10 in a recording medium and also transmits them to a detection PC 40. The detection PC 40 has stored an intermediate CA certificate of the intermediate CA 60 in a memory. The detection PC 40 verifies the M2M certificate 101 by using the M2M certificate 101 transmitted by the monitoring camera 10 and the intermediate CA certificate.SELECTED DRAWING: Figure 1
