Abstract
An authentication apparatus according to the present application includes an acquiring unit, a first specifying unit, a second specifying unit, and an authentication unit. The acquiring unit acquires context information on a target user who becomes a target for authentication. The first specifying unit specifies a belonging cluster based on information related to a plurality of cluster groups and the context information on the target user, in each of the plurality of the cluster groups. The second specifying unit specifies, for each belonging cluster based on a classification model used to specify a predetermined candidate user in the belonging cluster specified by the first specifying unit, a candidate user, in a partial candidate user group that belongs to the belonging cluster, who satisfies a predetermined condition. The authentication unit authenticates the target user based on information related to the candidate user specified by the second specifying unit.
