An Intelligent Fingerprint Reader with Strong Recognition Capability Against Pollution and Duplication

Abstract

The invention relates to an intelligent fingerprint recognizer with strong anti-pollution and duplication recognition ability, which comprises a shell on which a display screen, a voice announcer and several control buttons are arranged, and a liquid injection pipe and a plug are arranged on the top of the shell , the bottom of the casing is provided with an opening, and the casing is provided with a closing mechanism, a cleaning mechanism and a detection mechanism. The closing mechanism includes a fixed plate, a fixed block, a first spring, a first connecting rod, a second connecting rod and a closing plate. The detecting mechanism includes The detection component and the translation component, the cleaning mechanism includes a cleaning box, a water pipe, a flat plate, a cleaning strip and two second springs. The anti-pollution and copying intelligent fingerprint reader with strong recognition ability seals the opening through the closing mechanism to prevent external The identification window in the casing is damaged by debris pollution. Not only that, after the detection is performed by the detection mechanism, the identification window is cleaned by the cleaning structure to ensure the cleanliness of the identification window while preventing fingerprints from being stolen and ensuring safety.

Description

technical field [0001] The invention relates to the field of biological identification equipment, in particular to an intelligent fingerprint identifier with strong anti-pollution and duplication identification capabilities. Background technique [0002] The fingerprint reader is a high-tech security product that combines the fingerprint collection head and its supporting software to strengthen the encryption of personal computers. Using its supporting application software, it can implement power-on security, screen protection security, and file and directory security. When decryption is required, the user only needs to place his finger on the fingerprint window for identification. [0003] However, in order to facilitate data collection, most of the existing fingerprint readers fix the fingerprint window on the surface of the instrument. This design will easily cause the fingerprint window to be polluted and damaged by external debris. When pouring hot drinks, coffee or bo...

[0003] However, in order to facilitate data collection, most of the existing fingerprint readers fix the fingerprint window on the surface of the instrument. This design will easily cause the fingerprint window to be polluted and damaged by external debris. When pouring hot drinks, coffee or boiled water on the fingerprint window, it is easy to cause damage to the internal fingerprint sensor. Not only that, but the fingerprint window is exposed to the outside. Due to the failure to clean and maintain the fingerprint window in time, the residual fingerprint traces on the fingerprint window are easy to be damaged by some Used by criminals to copy, thus reducing the security of the fingerprint reader
