Fingerprint identification system and method

Abstract

The invention discloses a fingerprint identification system and method, and the system structurally comprises a door handle and a fingerprint device, the fingerprint device is arranged on the door handle, a cavity is formed in the door handle, an opening is formed in the door handle, the opening is communicated with the cavity, the fingerprint device is composed of a fingerprint sensor, a lifting device, a transmission device, a protection device and a wiping device, the protection device is arranged at the opening, the wiping device is arranged above the protection device, the fingerprint sensor is arranged on the side face of the wiping device and connected with the lifting device, the bottom of the lifting device is in transmission connection with the protection device through the transmission device, and the lifting device is composed of a spring, a rotary disc, a nut, a lead screw, a guide rail and a wire wheel. The invention has the following beneficial effects that: while protection is achieved, no electricity is used, and energy-saving and environmental protection are achieved; a user can use a correct gesture to perform verification, so that the verification accuracy and efficiency are improved; the possibility that fingerprints are stolen is avoided, and the safety is improved; and a sponge wheel can be recycled, and the cleaning effect is better.

Description

[0001] This application is a divisional application with an application date of March 25, 2019 and an application number of CN201910227932.2, which is an anti-theft hidden fingerprint recognition device. technical field [0002] The invention relates to the technical field of fingerprints, in particular to a fingerprint recognition system and method. Background technique [0003] Fingerprint recognition technology is widely used, and fingerprint recognition technology can be seen in access control and time attendance systems. [0004] At present, fingerprint door locks should be widely used. In order to avoid damage, the patent application No. 201820403840.6 proposes that the fingerprint sensor can be concealed by rotation to avoid damage, but this design needs to be rotated by a motor during use, which will accelerate the consumption of batteries. Power, reduce the length of power consumption. When in use, the fingerprint will be printed on the fingerprint sensor. If it is ...

[0004] At present, fingerprint door locks should be widely used. In order to avoid damage, the patent application number 201820403840.6 proposes that the fingerprint sensor can be concealed by rotation to avoid damage, but this design needs to be rotated by a motor during use, which will accelerate the consumption of batteries. Power, reduce the length of power consumption. When in use, the fingerprint will be printed on the fingerprint sensor. If it is not erased in time, it is easy for someone to steal the fingerprint and copy it, which reduces the safety factor. When the fingerprint is pressed, the angle deviates from the original fingerprint When , the verification time will be extended, which may lead to failure of verification and misjudgment
