PROBLEM TO BE SOLVED: To suppress decrease in authentication accuracy while suppressing increase of verification processing time in one to N authentication.SOLUTION: Vein data representing a vein image and feature quantities are extracted from an image acquired by an image acquisition unit 2, and the vein data and the feature quantities are stored in a storage unit 5. The feature quantities include a first feature quantity that represents relationship between two segments of a plurality of segments obtained by vectorizing the vein image.【課題】１対Ｎ認証において、照合処理時間の増加を抑えつつ、認証精度の低下を抑える。【解決手段】画像取得部２により取得された画像から静脈像を示す静脈データ及び特徴量を抽出し、静脈データ及び特徴量を記憶部５に記憶させる。特徴量は、静脈像をベクトル化して得られる複数のセグメントのうちの２つのセグメントの関連性を示す第１の特徴量を有する。【選択図】図１
