Abstract
An identification device according to one embodiment includes a vibration generation unit that generates, by a vibration generator, first vibrations to be provided to a three-dimensional object to be identified having an integrated structure; an acquisition unit that acquires, from a vibration detector, a detection signal corresponding to a second vibration that has propagated inside the three-dimensional object among the first vibrations provided to the three-dimensional object; a feature quantity generation unit that generates a feature quantity indicating a frequency characteristic of the second vibration, based on the acquired detection signal; and an identification unit that identifies the three-dimensional object to be identified, based on a feature quantity stored in a storage device in which the feature quantity indicating a frequency characteristic based on a vibration that has propagated inside a previously identified three-dimensional object is stored and on the feature quantity generated by the feature quantity generation unit.
