Abstract:
A signature to be used to verify whether or not an original version video captured by a camera has been altered is assigned in the camera to improve the evidential quality of the original version video captured by the camera. The camera ( 2 ) includes: an image pickup unit that captures a video of an area to be monitored; a CPU that generates, using a portion or the entirety of video data of the area to be monitored captured by the image pickup unit, a signature for verifying whether or not the video data have been altered; and a network communication unit that sequentially transmits, to a client terminal ( 4 ), signed video data obtained by assigning the signature generated by the CPU to the video data. The client terminal ( 4 ) includes: a network communication unit that receives the signed video data that are sequentially transmitted from the network communication unit; a CPU that verifies whether or not the video data included in the signed video data received by the network communication unit have been altered; and a display ( 43 ) that outputs the result of the verification performed by the CPU.

Claim (Index 1):
A signature generation system, comprising:\n a capturing device and a user terminal which are connected to each other, wherein the capturing device includes a capture that captures a video of an area to be monitored, a signature generator that generates a signature for verifying whether or not the video data has been falsified using all or a part of video data of the area captured by the capture, and a transmitter that sequentially transmits, to the user terminal, signed video data obtained by assigning the signature generated by the signature generator to the video data, and the user terminal includes a first receiver that receives the signed video data sequentially transmitted from the transmitter, a verifier that verifies the presence or absence of falsification of video data contained in the signed video data received by the first receiver, and an output portion that outputs verification results by the verifier.
