Embedded Wireless Fingerprint Exam Affair Management

This thesis studies the design method of fingerprint identification module based on embedded system, which can realize the design of wireless fingerprint examination management system.This method reduces the hardware cost by building hardware environment whose platform is ARM9 microprocessor and MBF200 fingerprint sensor-integrated module. And, under the enviroment of Linux, adopting framework for embedded fingerprint identification system and introducing relevant technology about fingerprint identification, the design of distributed fingerprint identification system could be realized, which is low-cost and reliable. Meanwhile, by combining wireless network communication with Ethernet communication, it can maintain real time data exchanege with central data bank. This system adopts SQL Server database to manage usres’ baisc information and information data of their fingerprints’ characteristics and runs reliably. Comprehensive tests and practical application proved that fingerprint images collected by this system are more clear and less fuzzy. After being processed, the outlines of images are clear and have outstanding features, so that it is easy to classify and identify fingerprints. This system could be applied in the management of large-scale examinations and remote network examination. It also improves traditional checking way which identifies person by his holdings, and is the future direction of examination management.
