Abstract

The present invention proposes a fingerprint identification method, device and terminal. The fingerprint identification method includes: collecting a fingerprint image; extracting features in the fingerprint image; judging whether the person to be verified is a living body according to the features; if the person to be verified is a living body , and perform fingerprint matching to obtain the fingerprint matching result. The method can improve the security of fingerprint identification.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a fingerprint identification method, device and terminal. Background technique [0002] As a unique feature of the human body, fingerprints are lifelong invariant, unique and convenient. Today, fingerprint identification technology has been widely used in acquisition systems, access control systems, smart phones, smart phones and other equipment. With the continuous popularization of payment functions in smart phones, fingerprint recognition technology is further applied to application functions such as online fingerprint payment on the basis of smart phone fingerprint unlocking. [0003] In the related art, the fingerprint identification technology usually adopts the features of the fingerprint pattern in the fingerprint image. However, illegal users can imitate fake fingerprints according to the obtained fingerprint pattern features, and use the counterfeit fake f...
