    摘要: A high-speed moving object (100) includes: a first communication unit (101) which transmits image data captured by an image capturing unit (103) over radio wave of the first frequency (f1); and a second communication unit (102) which transmits the image data over radio wave of the second frequency (f2) in the similar manner. A base station (200) includes a communication unit (201) which transmits control data indicating a timing of transmission over radio wave of a predetermined frequency, and each of the base stations (200a, 200b . . . ) perform communication over radio wave of the first frequency (f1) and radio wave of the second frequency (f2). A control center (300) includes a selection unit (302) which selects one image data from a plurality of image data, when there are, among the image data transmitted from the base station (200), the plurality of image data that have been captured by the identical image capturing unit (103) at the same time.

    摘要: Two El Gamal ciphertexts, which are input to a two-input two-output unit switching gates SW forming a permutation network, are randomized with a random number and randomly permuted, and a zero-knowledge proof, which proves the correspondence between the inputs and outputs of the switching gates SW, is output to a verifier without revealing the random number and the random permutation. A decryption unit decrypts ciphertexts from a unit switching gate SW in he last column through the use of a secret key, and proves in zero-knowledge the validity of the decryption without revealing the secret key. A verification unit verifies the proof of each unit switching gate and the proof of the decryption unit.

    摘要: A video camera includes a viewfinder through which an operator may view an image of an object to be videoed, a rotatably supported head-carrier cylinder and a capstan for transporting a length of magnetic recording medium. This video camera also includes at least one of first and second detecting units for detecting a change in rotation of the rotary head-carrier cylinder and for detecting a change in rotation of the capstan, respectively, and a determining unit operable to determine, in reference to information supplied from at least one of the first and second detecting units, whether or not a video recording then taking place is in accordance with the will of an operator. The video camera may be provided with at least one of a camera wobbling detector and an eye sensor for detecting whether or not the operator looks through the viewfinder and, in such case, the determining unit makes the determination in reference to information supplied from one of the camera wobbling detector and the eye sensor and that from at least one of the first and second detecting units.
