Problems solved by technology

Fake fingerprints are generally made of printed paper or film, or made of silica gel or rubber. The texture is roughly the same as that of real fingerprints. Therefore, it is difficult to identify real and fake fingerprints with existing fingerprint recognition technologies.

Abstract

The invention discloses a fingerprint identification method and device. The method comprises the steps that the fingerprint identification device can collect a fingerprint image for a target object; a target fingerprint line is determined from the fingerprint image, and whether the target fingerprint line has sweat gland holes is determined; if the sweat gland holes exist, the fingerprint of the target object is determined as a fingerprint living body; if the sweat gland holes do not exist, the fingerprint of the target object is determined as a fingerprint prosthesis. According to the invention, the fingerprint identification device can identify the sweat gland holes in the fingerprint image, and identifies whether the fingerprint is genuine or sham based on the presence or absence of the sweat gland holes in the fingerprint image; genuine or sham fingerprints can be accurately identified; and the security of fingerprint identification is improved.

Description

technical field [0001] The invention relates to the technical field of biological identification, in particular to a fingerprint identification method and device. Background technique [0002] Fingerprint refers to the uneven lines on the front skin of the user's finger end. Fingerprint identification refers to identification by comparing the detailed feature points of different fingerprints. Since fingerprints are different for different users, fingerprints can be used for identification. At present, fingerprint recognition is widely used in access control attendance, e-commerce transactions, financial transactions, personal computers, mobile phone security and settlement systems. [0003] With the development of fingerprint identification technology, fingerprint identification equipment is excellent in terms of convenience and correctness, but there is also the problem of false authentication of false fingerprints. False fingerprints are generally made of printed paper o...
