Fingerprint identification technology is a kind of important biological identity recognition technology; it is also the most mature branch of biological recognition technology development. Comparing with other biometric identification technology, fingerprint identification technology has high efficiency, low cost, convenient collection etc advantages. Now the development of the fingerprint recognition system becomes faster and faster, in order to meet the needs of the society, the development and application of embedded system also should follow closely the development direction of fingerprint identification technology to optimize the fingerprint identification algorithm, and develop with high recognition rate, fast processing speed, good scalability and low cost embedded platform, which has a broad market prospect and research value.
