Embodiment Construction

[0056]Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0057] In related technologies, a solution to the use of residual fingerprints is to judge the displacement information of the fingerprint image used in this unlocking and the fingerprint image used in the previous unlocking when unlocking. The source of the fingerprint image is the in-plane fake fingerprint. However, since the position of the fingerprint collection area is fixed, when the user ...

Abstract

The invention relates to a fingerprint identification method and device, and relates to the field of intelligent terminal security. The method comprises the following steps: judging whether a screen receives a screen pressing operation matched with a fingerprint image or not under the condition that the fingerprint image is acquired by an under-screen fingerprint sensor; under the condition that the screen receives a screen pressing operation matched with the fingerprint image, performing fingerprint identification on the fingerprint image. According to the method disclosed in the technical scheme provided by the invention, reliable and accurate mistakenly acquired fingerprint image elimination is realized.

Description

technical field [0001] The present disclosure relates to the field of smart terminal security, and in particular to a fingerprint identification method and device. Background technique [0002] After the fingerprint identification scheme in the mobile phone industry has experienced the scratch type and push type (that is, the capacitive scheme), it has gradually begun to adopt the under-screen fingerprint scheme on high-end models. However, if the fingerprint of the user's unlocking finger remains on the screen, it can be used by others to perform the unlocking operation. For example, use a conductor to trigger the fingerprint unlocking process, and the fingerprint sensor under the screen collects the fingerprint image left on the screen, and the phone will be unlocked. [0003] A solution to the use of residual fingerprints is to judge the displacement information between the fingerprint image used in this unlock and the fingerprint image used in the previous unlock when u...
