In fingerprint technology, a concern is the use of models or severed finger tipsfor unauthorized access. Herein, a fingerprint sensing device is disclosed for distinguishing images of live fingerprints from those of other images. The device has a flat surface for receiving a finger; an infrared light source for irradiating a finger placed on the surface, and, a detector for detecting the infrared light and determining a state of the imaged fingertip.

n sujet d'inquiétude en dactyloscopie électronique est l'utilisation de modèles ou d'extrémités digitales coupées pour accès non autorisé. On présente ici un capteur dactyloscopique permettant de distinguer les images de doigts vivants d'autres types d'images. Le dispositif comporte une surface plane où l'utilisateur pose le doigt; une source de lumière infrarouge, qui irradie le doigt; et un détecteur qui détecte la lumière infrarouge et détermine l'état de l'extrémité digitale vue par l'instrument
