In the current network technology, the embedded terminal capable of providing biometric technology is mature and the price is cheap, at present technology of fingerprint recognition is the most widely, we can not only see the fingerprint recognition technology in access control, attendance system, fingerprint recognition application is more on the market: such as mobile phone, fingerprint lock, bank payment verification can be applied to fingerprint recognition technology.In the fingerprint recognition and control field, we will also use a variety of micro controller, this paper uses Samsung S3C6410 as the control core, S3C6410 application designed for high performance, low cost, low power embedded consumer electronic design based on ARM9 kernel. According to performance is divided into two different series: this series of core clock frequency has reached 72MHz.Fingerprint identification two feature points based on: (I) to identify the fingerprint feature structure fingerprint (II) feature local. This paper proposes a can be used in automatic fingerprint recognition system of fingerprint recognition algorithm based on feature points. The methods me
