Classification: CPC G  A | IPC A  G

Claim 0:
1. An authentication device comprising:
a ring;
a first sensor configured to acquire fingerprint information;
an authentication circuit configured to perform authentication based on fingerprint information stored in the ring and the acquired fingerprint information;
a controller configured to cause a function of the ring to be active based on a result of the authentication by the authentication circuit;
a second sensor configured to detect acceleration of the ring;
a plurality of third sensors, each configured to detect a distance to a finger inside the ring, the plurality of third sensors being provided on a circumference of the ring; and
a determination circuit configured to determine that the ring is positioned at an authentication position based on the acceleration detected by the second sensor and distances to the finger inside the ring detected by the plurality of third sensors,
wherein the authentication circuit is configured to perform the authentication when it is determined that the ring is positioned at the authentication position by the determination circuit.
