Abstract
(EN)
Disclosed are a method for fingerprint recognition, and an electronic device, wherein same can enhance the security of fingerprint recognition under a screen. The method for fingerprint recognition is applied to an electronic device provided with a touch display screen, wherein the touch display screen comprises a fingerprint recognition area. The method comprises: acquiring capacitance information of a fingerprint recognition area when the fingerprint recognition area is pressed by an object; determining, according to the capacitance information, whether the object is a human finger; and when the object is a human finger, carrying out fingerprint identification on the object.

La présente invention concerne un procédé de reconnaissance d'empreintes digitales et un dispositif électronique permettant d'améliorer la sécurité de la reconnaissance d'empreintes digitales sur un écran. Le procédé de reconnaissance d'empreintes digitales est appliqué à un dispositif électronique doté d'un écran d'affichage tactile, l'écran d'affichage tactile comprenant une zone de reconnaissance d'empreintes digitales. Le procédé comprend les étapes consistant à : acquérir des informations de capacité d'une zone de reconnaissance d'empreintes digitales lorsque la zone de reconnaissance d'empreintes digitales est pressée par un objet ; déterminer, en fonction des informations de capacité, si l'objet est un doigt humain ; et lorsque l'objet est un doigt humain, effectuer une identification d'empreintes digitales sur l'objet.
