FingerPrint Identification System Based On Sumsung ARM S3C2410

Fingerprint verification is an important biometric technique for personal identification which is also the maturest 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 S3C2410 with the embedded operating system Linux.Second, this paper gives some introduction of Linux, and then we design the hardware of the system, select the chips, confirm their working mode and draw the corresponding datasheet. As the software aspect, we chose the classical steps of image enhancement, binary, thin, and minutiae extraction. The paper analysed the idea, advantages and disadvantages of available algorithms of the steps, selected the best one of each step, and constructed a faster, new algorithm which can thin the image of fingerprint.
