Abstract: A user device includes: a holding unit that holds confidential information; a generation unit that generates a generator; an arithmetic unit that calculates a commitment corresponding to the generator, on the basis of the generator and the confidential information; and an acquisition unit that transmits, to a first external device, an acquisition request including the generator and the commitment corresponding to the generator, to acquire a verifiable claim (VC) including the generator and the commitment corresponding to the generator. In the user device, the value of the generator the acquisition unit uses to newly acquire the VC is different from the value of the generator the acquisition unit has used to acquire the VC in the past.

Abstract: A verification system includes: a content acquisition unit that acquires, from a user terminal of a user, content data provided to an external information processing system providing an environment in which content can be used; a relationship information acquisition unit that acquires, from the user terminal, relationship information indicating a relationship between the user and the content data under the environment in association with the content data; and a verification unit that verifies that the user is a valid right holder of the content data based on the relationship information.

Abstract: A synchronization controller performs control so that operator motion data is transmitted to a robot when a synchronization switch is set to ON which allows synchronization of a rotational motion of an operator with a rotational motion of the robot. An image correction unit, when there is a difference between a first rotation angle of the operator and a second rotation angle of the robot, corrects a cutout range of an image so as to be equal to a range corresponding to the first rotation angle. The synchronization controller performs control so that the operator motion data is not transmitted to the robot when the synchronization switch is set to OFF which does not allow synchronization of a rotational motion of the operator with a rotational motion. The image correction unit corrects the cutout range so as to be equal to a range corresponding to the first rotation angle.

Abstract: When a controller controls a driver so as to move a moving unit in accordance with a user's movement, the controller controls a video signal processor such that frame videos of a video signal transmitted to an image display device have a first display mode. When the controller controls the driver so as to move the moving unit regardless of the user's movement, the controller controls the video signal processor such that frame videos of a video signal transmitted to the image display device have a second display mode.
