Title The Design of Fingerprint Identification System Based on MSP430 MCU
Abstract
It is no doubt that fingerprint identification is the most common biometric modality, which can be used to authenticate the identity of a person. Automatic identification systems based on fingerprint recognition have been extensively deployed in the industrial and forensics area. Because of the huge market prospect of fingerprint identification technology, this paper focuses on the design of fingerprint identification system. With MSP430F149 development board as the platform, using MSP430F149 serial port connects FM-180 fingerprint identification module. According to the requirements of instruction of the fingerprint identification module, we use C language programming to achieve the fingerprint identification system based on serial port communication by adopting the method of structured programming, in the IAR programming environment. Finally after the test, the system performs well: Under the coordination of the software and hardware modules, the system completes the fingerprint acquisition, matching and empty; Users use buttons for the control and mode switching function; And the LCD module displays the related message. This system has the advantages of simple design, excellent performance and has a certain practicality.

1 绪论
随着网络的普及和电子商务的快速发展，人们需要越来越多地依靠密码、数字证书、身份证和IC卡等个人身份认证方式进行安全认证，但这些传统的方式都或多或少的存在可破译、可盗用、可伪造等漏洞，所以迫切需要找到一种可以替代传统识别技术的，更加可靠安全的技术，于是生物识别技术出现在了人们的视线当中，这种技术要求被识别的对象必须具有一定的特性，比如长期不变性和唯一性等。而事实已经证明，作为其中之一的指纹识别技术无疑是目前应用最热，最有前景的传统识别技术的接替者。因此，对于以低成本单片机和指纹识别模块等组成的嵌入式指纹识别系统的研究与设计显得很具有实用价值。
