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.

Abstract: An authentication system includes a terminal having a transmitter, a processor, and a memory, and a server having a receiver, a processor and a memory. The terminal transmits request information to the server. The terminal acquires time information, generates a first one-time password at a pre-determined cycle by using the time information within the terminal, and generates encryption information which is acquired by encrypting the request information using the first one-time password as a key, the encryption information being transmitted from the terminal to the server. The server acquires time information within the server, generates a second one-time password at the pre-determined cycle as the cycle within the terminal by using the time information within the server, generates reference information which is acquired by decoding the encryption information using the second one-time password as a key, and compares the request information with the reference information.

Abstract: Provided is an authentication system in which a client terminal that receives input of request information is connected to a server that executes a process with regard to the request information. The client terminal includes: a first authentication information generation unit that generates first authentication information based on information which is shared with the server; an encryption unit that generates encryption information; and a transmission unit that transmits the request information and encryption information to the server. The server includes: a reception unit that receives the request information and encryption information; a second authentication information generation unit that generates second authentication information; a decoding unit that generates reference information which is acquired by decoding the encryption information using the same common key method as in the client terminal while using the second authentication information as a key; and an authentication unit that compares the request information with the reference information.
