In this paper provides the design method of wireless fingerprint attendance system based on Zigbee technology. The system includes terminal fingerprint acquisition module and attendance management module through computer. It can realize automatically such functions as information acquisition of fingerprint, processing, wireless transmission, fingerprint matching, and attendance management. This attendance management system aims at providing an easy and time saving attendance system that verifies the employee's attendance system at an organization using their fingerprint during the attendance time. When a employee is first enrolled in a fingerprint-based biometric attendance system, the software records a pattern of the employee's fingerprint using a scanner and associates that pattern with the employee's identification number. This template measures the connection between various points in the fingerprint. At the time of attendance, the system verifies that the newly scanned fingerprint matches the pattern originally stored for that identification number. If there is a equal, the knock is recorded. The system will eliminate buddy punch. It will efficiently replace the manually maintained records and the conventional time consuming way of marking attendance. The system may also record the employee's outgoing and incoming time during the days, thus facilitating organizations. In order to achieve the simple and high real-time system, it realized low-cost and highperformance wireless fingerprint attendance function, which provided a new wireless fingerprint attendance system for enterprises and institutions. The earlier fingerprint image enhancement methods are FFT based and has a drawback of poor image quality which results in unreliable minutiae extraction and thereby reduces the accuracy of recognition result. In this paper, at the algorithm level a new approach for fingerprint image enhancement based on the Gabor filter is introduced. Comparatively this algorithm produced the good results in the view of image quality and accuracy. [ABSTRACT FROM AUTHOR] |
