1. An authentication device comprising:
a data acquisition unit that acquires spherical data including a video of a person taken by a fisheye camera;
a tracking unit that tracks a position of a person included in the spherical data that is continuously acquired by the data acquisition unit;
an identification unit that identifies, based on a tracking result obtained by the tracking unit, a person who is an object to which an authentication process is to be performed;
a determination unit that determines, for the person identified by the identification unit, whether to perform facial recognition performed by a spherical convolutional neural network or perform facial recognition performed by a convolutional neural network; and
an authentication performing unit that, for the person identified by the identification unit. performs facial recognition performed by the spherical convolutional neural network on the spherical data, when the determination unit determines that the facial recognition performed by the spherical convolutional neural network is performed.
