Embodiment Construction

[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0059] In the prior art, the traditional fingerprint identification technology acquires the fingerprint image through light or capacitance technology, but some abrasive tools made according to the fingerprint can also capture the fingerprint image, which seriously affects the accuracy and security of the fingerprint identification technology, and the finger It is unavoidable to leave fingerprints after contact with other objects. Forging new fingerprints throug...

Abstract

The present application provides a fingerprint collection and identification method and device, including: collecting a first fingerprint photo when the finger applies the first pressure value and a second fingerprint photo when the second pressure value is applied; The first fingerprint sample at the first pressure value, the second fingerprint sample when the preset finger applies the second pressure value, the first fingerprint photo and the second fingerprint photo are compared to the fingerprint photos that pass the legality check. Fingerprint recognition. This application improves the accuracy of fingerprint identification technology and the accuracy of finger liveness monitoring. At the same time, it takes into account the deformation of the finger when it is pressed, avoiding the failure of identification due to deformation of the finger, and preventing the fingerprint left by the contact between the finger and other objects from being detected. Misappropriation.

Description

technical field [0001] The present application relates to the field of fingerprint identification, in particular, to a pressure-based fingerprint acquisition and identification method and device. Background technique [0002] In recent years, the application range and scenarios of biometric identification technology have become wider and wider, especially in recent years, the integration of fingerprint collection equipment with mobile devices and terminals has made fingerprint identification technology one of the most widely used and most accepted biometric identification technologies. one. Moreover, the characteristics of fingerprints that are invariable, unique and convenient for life make fingerprint recognition technology almost become synonymous with biometrics. [0003] Fingerprint image acquisition is the first step in fingerprint identification, and the quality of the acquired image directly affects the subsequent fingerprint image identification process. There are...
