Problems solved by technology

Although the multi-spectral fingerprint collection method has greatly improved the recognition rate of true and false fingerprints, in the multi-spectral system, the number of spectrum types is small, and the detection method is easily affected by the outside world, so it is still not foolproof.

Embodiment Construction

[0022] The method will be further described below in conjunction with the accompanying drawings. In an embodiment, an optical fiber is selected as the optical waveguide device, and a spectrometer is selected as the spectral detector.

[0023] Step 1: Put your finger on the fiber-integrated optical window, use CCD or CMOS to collect the image, and analyze the defect degree of the image. If the image meets the preset integrity conditions, go to step 2; otherwise, it will prompt that the image does not meet the requirements and you need to The user re-collects after washing their fingers;

[0024] The optical window of the optical fiber integrated type is made of transparent glass, in a rectangular shape, and its size is equivalent to that of a normal adult's finger. At 2 / 3 of the long side and in the middle of the short side, there is a small hole with a diameter of 1mm. This small hole is used to place the common end of the Y-shaped fiber.

[0025] The Y-shaped optical fiber...

Abstract

The invention discloses a method for identifying whether fingerprints are true or false based on an optical mapping system. According to the method, the optical mapping system is integrated in a fingerprint detection window. The method includes the following steps that firstly, a finger is placed on the fingerprint detection window, a back-scattered spectrum is collected by the optical mapping system, and a fingerprint image is collected by an image collecting system at the same time; secondly, if the collected image meets the fingerprint integrity requirement, collected spectral data are compared with finger spectral data in a database; thirdly, if it is determined that an object to be detected is a true finger through spectrum comparison, the fingerprint image is analyzed so as to complete identity identification, and otherwise identification fails. By acquiring back-scattered spectrum information of the object to be detected through the spectrum technology in the process of collecting surface image information of the fingerprints, a finger of an organism can be distinguished from a finger mould.

Description

technical field [0001] The invention belongs to the intersecting technical field of photonics, information science and biological science, and in particular relates to a method for identifying true and false fingerprints based on an optical atlas system. Background technique [0002] Fingerprint recognition is an important identification method. Compared with DNA and iris recognition, it is easy to use and has been widely used in our lives. However, the ease of fingerprinting also poses limitations of this method. The endless fingerprint films, as fake fingerprints, can deceive many fingerprint identification systems. This also greatly reduces the effectiveness of existing fingerprint identification systems. As a simple identification system, many emerging technologies have been introduced into the fingerprint identification system to identify fake fingers. Among them, the fingerprint collection system based on multi-spectrum is one of them. Although the multi-spectral ...
