Abstract

La présente invention peut fournir des informations de guidage d'entrée d'empreintes digitales permettant de guider l'utilisateur de sorte que ledit utilisateur puisse réaliser un balayage tactile sur un détecteur de reconnaissance d'empreintes digitales lors de la réception d'une demande d'exécution d'au moins une fonction offerte par un terminal portatif. Le terminal portatif peut acquérir une image d'empreintes digitales conformément à un balayage tactile de l'entrée d'utilisateur en tenant compte des informations de guidage d'entrée d'empreintes digitales, et peut exécuter la ou les fonctions en authentifiant l'utilisateur à l'aide de l'image d'empreintes digitales acquise.
