The Hardware Platform Design Of Embedded Fingerprint Identification System

Fingerprint verification is an important biometric technique for personal identification which is also the most mature branch of biometric technique.As a rapidly evolving technology, fingerprint verification has been widely used in the field of criminal identification, and obviously it has the potential to be widely adopted in a very broad range of civilian applications such as banking security.The combination of fingerprint verification and embedded systems would make this technique suitable for many kinds of occasions.This paper did some elementary research on embedded automated fingerprint identification system, it mainly includes the following several aspects:First, this paper analyze the study actuality and development direction of this task, and explain the necessity of this task.Considering the high performance and low cost of ARM-chip,in this paper We construct an AFIS based on the processor S3C2440 with the embedded operating system Linux.Second, We design the hardware of the system, select the chips, confirm their working mode and draw the corresponding datasheet.As the software aspect, this paper gives some introduction of Linux,then constructed linux in the ARM hardware platform successfully including:Bootloader design,configuring linux kernel as well as YFFS file system. And this paper has accomplished the programs of ordinary interfaces. Finally, we debugged the system, achieved the basic functions of fingerprint identification system. The paperhas made the beneficial exploration to fingerprint identification system based on ARM,and help to further study on embedded fingerprint identification system.
