Problems solved by technology

[0005] In view of the fact that the fake finger forged by silicone can simulate the deformation of the finger and the characteristics of fingerprints and microvessels, which leads to problems such as easy to pass the 3D finger verification program of the fingerprint recognition device
Therefore, the main purpose of the present invention is to provide an identification method and identification device for authentic and fake fingerprints, so as to solve the problem that the fake silicone finger is easily verified by the fingerprint identification device.

Embodiment Construction

[0031] Please refer to figure 1 and figure 2 As shown, it is a schematic structural diagram and a schematic block diagram of the identification device of the present invention. The identification device 100 includes a pressing board 110 , a circuit board 120 , at least one light emitting element 130 , an image sensor 140 (image sensor) and a processing module 150 . Wherein, the light emitting element 130 , the image sensor 140 and the processing module 150 can all be configured on the circuit board 120 such that the processing module 150 is coupled to the light emitting element 130 and the image sensor 140 . Wherein, the light emitting element 130 may be but not limited to a light emitting diode.

[0032] The material of the pressing plate 110 can be but not limited to optical glass BK7 or polymethylmethacrylate (PMMA). In addition, the pressing plate 110 can be not only a light-transmitting flat plate, but also a trapezoidal or prism-shaped light-transmitting plate, which...

Abstract

The invention discloses a method and device for identifying authentic and fake fingerprints, including acquiring a fingerprint image; executing an analysis program, analyzing the fingerprint image with a first color model and obtaining a corresponding first chromaticity coordinate axis; executing a conversion The program converts the first chromaticity coordinate axis into a second chromaticity coordinate axis with a second color model; executes a verification program, and compares whether the second chromaticity coordinate axis meets a preset second skin color threshold; if If the second chromaticity coordinate axis meets the second skin color threshold, it is determined that the finger is a real fingerprint. The present invention also provides an identification device for performing the above steps.

Description

technical field [0001] The invention relates to an identification method and device, in particular to an identification method and identification device related to authentic and false fingerprints. Background technique [0002] With the advancement of technology, the importance of protecting personal data has also increased. At present, the most common way to verify the identity of the user is to input the account number and password by the user. When the input account number and password are correct, the electronic device allows the user to access. In order to ensure the complexity of the password, general electronic devices will limit the minimum length and character types of the password. However, when entering the password, it is easy to be skimmed by someone with a heart, so there is still a risk in entering the password. In addition, the user usually not only memorizes a set of passwords, which will cause the dilemma that the user forgets the set password. [0003]...
