Fingerprint identification device and identification method thereof

Abstract

The invention discloses a fingerprint identification device. The device comprises a fingerprint collector body, and is characterized in that the fingerprint collector body comprises two fingerprint collectors with a Camera communication interface and a USB communication interface respectively. The invention also discloses a fingerprint identification method which is characterized by sequentially comprising the following steps of: 1) initializing; 2) performing circuit self-examination; 3) performing a corresponding program according to information input by a user; 4) judging whether to perform communication; 5) acquiring image data; and 6) comparing registered users. The identification device and the identification method of the invention can be used for simultaneously comparing fingerprints by two users and simultaneously managing the fingerprint identification device by one or two managers; the comparison result can be synchronously displayed at a position corresponding to a liquid crystal display; and the device and the method have the advantages of saving cost, doubling the fingerprint identification efficiency, the reliability and the safety and more easily extending the functions of the fingerprint identification device.

Description

technical field [0001] The invention relates to a device or method for fingerprint identification using an electronic circuit, in particular to a fingerprint identification device and its identification method. Background technique [0002] Existing single-fingerprint identification devices generally use a fingerprint collector, which has relatively simple functions of collecting, identifying fingerprints, and management, and the identification efficiency is low. For example, only one user can perform 1:1 or 1:N comparison at the same time. And an administrator can realize the operation authority of the device. As for two-finger, three-finger, and more-fingerprint identification methods and identification devices, the amount of fingerprint image data collection is far greater than that of single fingerprint identification, which has the disadvantages of large size and high price, and its popularization and use is restricted.
