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 2):
The signature generation system of  claim 1 , further comprising:\n a recorder which includes a second receiver that receives the signed video data sequentially transmitted from the transmitter, and a recording portion that records the signed video data received by the second receiver, wherein the verifier verifies the presence or absence of falsification of video data contained in the signed video data using the signed video data read from the recorder.
