Abstract


Information security has been an important issue which the community concerned about since 21st century. With the development of IT technology, the traditional authentication, such as ID cards, IC cards, passwords and other methods have revealed the problems of vulnerability and security leak, resulting in serious security risks and economic losses. Therefore, people pay attention to biometrics. Palmprint based on biometric identification technology is a new research direction rised in recent years. Due to unique characteristics of palmprint, the inherent stability, and carrying the same basic characteristics of life, there are broad prospects for development. Traditional palmprint recognition systems rely on large-scale integrated circuits. The acquisition of palmprint image and the realization of recognition algorithms often require the support of huge hardware. Thus, the research of a set of portable, real-time, high-performance and low-cost embedded palmprint identification system has an important practical significance.Combined with the application of palmprint recognition technology to the embedded ARM technology, a hardware design with high-performance, low-cost palmprint identification system has been proposed in this thesis.The main points of this thesis are presented as follow:The palmprint identification technology and its development status have been introduced in this dissertation.According to the domestic and international development and market demand of palmprint identification system, a complete palmprint identification system hardware design based on ARM embedded technology is proposed. The design is mainly to deal with the core module, palmprint image acquisition module and control module.The design of ARM-based palmprint image acquisition system introduces key technology of image acquisition system as well as represents the hardware circuits and software programming of ARM-based palmprint image acquisition system in detail. Finally, it realizes the design and implementation of a ARM-based palmprint image acquisition system.The design of control system module greatly improves the overall performance of the system and provides a good hardware platform to help algorithm processing core ARM run recognition algorithm faster. At the same time, the control module offers an excellent man-machine user interface. Finally, it tests general summary of the system. Meanwhile, it analyzes the inadequacies of system at present and puts forward several suggestions for improvement.
