AUTHENTICATION DEVICE, AUTHENTICATION METHOD, AND AUTHENTICATION PROGRAM

To provide an authentication device, an authentication method, and an authentication program that can effectively use authentication processing while reducing time and cost required for introduction.SOLUTION: An authentication device of one form according to the present disclosure comprises: an imaging unit that picks up an image of a user to be authenticated; a display control unit that displays the image of the user picked up by the imaging unit on a display part; an authentication unit that authenticates personal properties of the user on the basis of collation between authentication information presented by the user whose image is picked up by the imaging unit and correct answer data registered in advance; and a determination unit that, when the user is authenticated by the authentication unit, determines start of subsequent authentication processing to be executed in a display mode in which the display part is divided into a plurality of areas according to attribute information or an authentication state of the authenticated user.SELECTED DRAWING: Figure 18 【課題】導入にかかる手間やコストを抑えつつ、認証処理を有効活用することのできる認証装置、認証方法および認証プログラムを提案すること。【解決手段】本開示に係る一形態の認証装置は、認証対象のユーザを撮像する撮像部と、前記撮像部によって撮像されたユーザを表示部に表示する表示制御部と、前記撮像部によって撮像された、前記ユーザが提示する認証情報と、予め登録された正解データとの照合に基づき、当該ユーザの本人性を認証する認証部と、前記認証部によって前記ユーザが認証されると、認証された当該ユーザの属性情報もしくは認証状況に応じて、前記表示部を複数の領域に分割した表示態様で実行される後続の認証処理の開始を決定する決定部と、を備える。【選択図】図１８
