  • Patent number: 11394709
    Abstract: An authentication device management device includes a generating unit, a registration unit, a transmission unit, and a responding unit. The generating unit generates a pair of a first key to attach a signature with respect to an authentication result obtained by an authentication device that performs personal authentication of a user, and a second key to verify the signature attached to the first key. The registration unit registers, in association with each other, the key identifier that identifies the generated key pair and user identification information. The transmission unit transmits the first key generated by the generating unit to the authentication device used by the user. When the responding unit accepts a transmission request for the second key related to the authentication device in which the first key transmitted by the transmission unit has been set, the responding unit responds by instructing the authentication server to transmit the second key.
