Design And Realization Of Auto-guard Fingerprint Identification Control System

Personal identification is always needed in daily life, and the traditional method is through the token, password and so on, but with consciousness-raising in security, its limitation grows more and more prominent. As more safety, confidentiality and convenient than the traditional method, biometric identification technology has a great development, with disadvantage of lifetime invariant, unease amnesia, long-term carried, etc. At present, many of the biometric technology, fingerprint recognition technology is convenient, reliable, cheap and easy to accept, and in the past ten years fingerprint identification attracted great attention, and there was great progress on fingerprint structure, fingerprint acquisition technology and the development of commercial automatic fingerprint identification system. With the development of fingerprint identification technology, automatic fingerprint identification system will be applied more and more widely.The automobile industry is one of the pillar industries in China's economic development, both production and sales in recent years have maintained rapid growth. The automobile is Convenient for people's life, and simultaneous the problem of safety anti-theft has been paid attention to increasingly. The auto-guard technology based on fingerprint identification utilizes the human fingerprint as a key to start the car, greatly enhance the safety of automobile.The auto-guard system based on fingerprint identification in this paper studied is constructed dual-processor embedded system by SCM and DSP, and legal identity is recognized by the human fingerprint as a password, it greatly improves the safety of the system. This article is about the design and realization of auto-guard control system based on fingerprint identification, including the contents as follow: general framework, fingerprint acquisition, SCM control systems and Human Computer Interface. In specific design, comprehensive consideration of the cost, performance and other factors, the major work carried out are:1, General framework design of Auto-guard System based on Fingerprint Identification, based on SCM and DSP;2, Acquiring fingerprint image based on swipe sensor AES2510 of AuthenTec company;3, Realizing the design of peripheral circuit of SCM control system and monitoring program;4, Designing Human Computer Interaction of Auto-guard system based on Fingerprint Identification, mainly related to the keyboard and LCD display circuit and program, and completing system function design based on the hardware platform, including fingerprint registration, fingerprint deletion and fingerprint registry, etc.General framework of Auto-guard System based on Fingerprint Identification is given first in the dissertation, then module design is narrated in detail in each chapter, and finally a full text summary is made, and further suggestions and improvement is put forward. Experiments show that the system is reasonable and feasible, and has high practical value and broad application prospects.
