| In recent years, with the rapid spread of network informationization, fingerprint recognition system has occupied a large market space, and the embedded fingerprint recognition system in this field have a better development. Fingerprint recognition technology is a researched deeply^widely used and relatively-matured biometric identification technology. Fingerprint recognition system has better reliability and security, so the fingerprint recognition system has been widely applied to all aspects of people’s lives. Fingerprint recognition module can not process the data alone, but if working with embedded systems which will greatly enhance the efficiency, and make the fingerprint recognition system no longer limited to the space and the environment, thereby make it widely used in a variety of needs.This paper combined embedded technology、ingerprint recognition module and WiFi wireless communication technology, designed a function over the entire embedded fingerprint recognition system, completed the function of image acquisition processing、comparison and verification and wireless transmission. This paper describes the overall design of the system development platform and compares with the specific application modules and wireless communication technology. Secondly, this paper detailed the design of the hardware and software of the system. Finally, detailed the software platform building and the specific development process of the system. The design through to the fingerprint image acquisition and the extraction、transmission and comparison of eigenvalues, ultimately achieve a rapid authenticate the user. The system is a kind of embedded fingerprint recognition system that easy to use, highly security and low cost. |
