False fingerprint recognition method and device

Abstract

The invention discloses a false fingerprint recognition method. The method includes the following steps: (1), arranging a fingerprint collection end; (2) arranging a recognition storage module connected with the fingerprint information collection end; (3), embedding a fingerprint image information processing algorithm in the recognition storage module; (4), acquiring a to-be-recognized fingerprint image A through a camera; (5), acquiring a to-be-recognized fingerprint image B through a pressure-sensitive sensor; (6), matching the to-be-recognized fingerprint image A with the to-be-recognized fingerprint image B, and if the to-be-recognized fingerprint image B cannot be generated or the to-be-recognized fingerprint image B can be generated clearly while the to-be-recognized fingerprint image A and the to-be-recognized fingerprint image B deviate in fingerprint position, indicating that fingerprint is false; if the to-be-recognized fingerprint image B can be generated clearly and the to-be-recognized fingerprint image A and the to-be-recognized fingerprint image B are completely coincident in fingerprint position, indicating that the fingerprint is true, and completing false fingerprint recognition. The invention further discloses a device implementing the method.

Description

technical field [0001] The invention relates to the field of fingerprint identification, in particular to a false fingerprint identification method and a device for implementing the method. Background technique [0002] With the development of science and technology, and due to the singleness of fingerprints, more and more fingerprint collection devices use fingerprint collection and identification to judge people's identity or directly replace passwords to avoid mistakes and ensure safety. The traditional fingerprint collection method is to collect fingerprints by linear scanning and capacitance potential difference, which have the problems of large volume, low efficiency and high cost respectively. Moreover, this method is very cumbersome and error-prone in subsequent identification processing, resulting in certain defects in its reliability. [0003] The traditional fingerprint identification adopts optical reflection, linear scanning and capacitance potential difference...

Problems solved by technology

The traditional fingerprint collection method is to collect fingerprints through linear scanning and capacitance potential difference, which have the problems of large volume, low efficiency and high cost respectively.

Moreover, this method is very cumbersome and error-prone in the subsequent identification process, resulting in certain defects in its reliability.

[0003] Traditional fingerprint identification uses optical reflection, linear scanning and capacitance potential difference to collect fingerprints and realize fingerprint identification, but none of them can effectively identify fake fingerprints, and the security and reliability are low.
