Anti-cheating fingerprint attendance machine control method

Abstract

Anti-cheating fingerprint attendance machine control method is disclosed, and environment temperature sensor is arranged on the shell of the attendance machine, a finger temperature sensor is arrangedon a collecting window of a fingerprint collector of the attendance machine, after an environment temperature correction value and a temperature threshold value are set, environment temperature and finger temperature are collected while fingerprint collection is carried out, after the attendance is finished, an attendance machine controller extracts data in a memory for checking, and informationis sent to an attendance management personnel to confirm the authenticity of the attendance information of an employee after an object is found by the checking. According to the anti-cheating fingerprint attendance machine control method, based on the the characteristic that most of silica gel is not thermally conductive, suspected attendance information of a silica gel finger model can be identified by detecting the finger temperature of the employee in the attendance checking process, checking by the attendance management personnel is facilitated, the false alarm rate is low, the labor intensity of the attendance management personnel is not obviously increased, a cheating attendance phenomenon can be recognized to a certain degree, and the attendance checking effect is guaranteed.

Description

technical field [0001] The invention relates to an attendance machine, in particular to a control method for a fingerprint attendance machine. Background technique [0002] Attendance equipment is the enterprise's assessment of employees' commute time and attendance rate. Attendance equipment can improve employees' time concept and improve work efficiency. Most of the existing time attendance machines are divided into fingerprint, punch card, face recognition, pupil recognition, etc.; usually, in order to avoid employees punching cards to a certain extent, and do not want to increase a lot of attendance costs, most of them use fingerprint time attendance machines for attendance. [0003] The core of the fingerprint time attendance machines currently on the market is a small laser scanner. What the laser scanner on the fingerprint time attendance machine scans is not the finger, but the indentation formed when the finger touches the scanning window. Whether the blue laser or...

[0003] The core of the fingerprint time attendance machines currently on the market is a small laser scanner. What the laser scanner on the fingerprint time attendance machine scans is not the finger, but the indentation formed when the finger touches the scanning window. Whether the blue laser or the red laser is used, the scanned image is transmitted to the computing circuit in black and white format; therefore, many employees usually use plasticine to make a mold in order to deceive the fingerprint collector, and then use a silicone sleeve The simulated fingerprints can be obtained after entering the stereotypes. The existing attendance machines basically cannot recognize the silicone fingerprint cover, which seriously affects the effect of attendance.

[0004] Prior art Chinese patent CN104464009A discloses a fingerprint identification-based attendance system. Although the attendance system can also detect the body temperature of employees, it measures the actual body temperature of each employee. Attendance function
