Candidate Fingerprint Verification System Based On ARM9

In daily life, it is common to verify others by checking the ID card information. Due to the fact that ID cards are easy to be forged, great hidden troubles exit in the process of verifying the candidate's identity. With the development of bio-metric information technology,fingerprint identification technology can improve the efficiency of the identification of candidates effectively, and ensure the accuracy of the examiners when verified identity information.The paper analyzes and studies the operating principle, working process of fingerprint verification system. Based on the accuracy and rapidity of fingerprint verification system,proposed design scheme of fingerprint verification system.Fingerprint verification system hardware includes core processing module, fingerprint module, WIFI module. Fingerprint recognition algorithm studied and improved to realize fingerprint image preprocessing, feature extraction and matching. The fingerprint recognition algorithm improves the accuracy and rapidity of fingerprint verification. Write system applications to achieve the various functions of the system including fingerprint information input, query, delete, verify, fingerprint information upload and download. Using the GUI tool to develop the interactive interface of the system, make login, fingerprint entry, verification and other functions of the window.Establish the database of fingerprint verification system to achieve the fingerprint information storaging and deleting, and through the WIFI to achieve the fingerprint information uploading and downloading.Through the software and hardware debugging and tesing comprehensivly the performance of fingerprint verification system,and analyze the test result.The fingerprint verification system has a good performance, high accuracy.The system runs stably and meets the design requirements.
