Research Of Fingerprint Verification Based On MBF200

Fingerprint verification is an important biometric technique for personal identification. And it 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 be suitable for many kinds of occasions.The dissertation focuses on recognition of fingerprint. Based on current theoretic framework, a complete algorithm of fingerprint recognition has been accomplished on Visual C++. Attentions have been given to some problems for further improvement. The main contributions of our work reported in this thesis are as follows:(1) The basic concept of the biometric identification system and the familiar biometric identification techniques are summarized. The structure, principle and the Research status of AFIS are introduced. The key Problems in AFIS are analyzed.(2) The technology of fingerprint image acquisition is studied. The relevance definition and function index of fingerprint image acquisition is introduced. And comparing the technology of fingerprint image acquisition.(3) It introduces algorithms in fingerprint image processing with division, enhancement, binary, thin, features extraction and fake features reject. It analyses the idea, advantages and disadvantages of available algorithms of every steps, selected and improve the best one of each step considering of our system, complete the corresponding development and realize the whole system primarily.(4) Minutiae extraction and fingerprint identification algorithms based on the Minutiae matching algorithms of fingerprints are researched. The existed minutiae Extraction and matching algorithms are reviewed. And based on the study of existed methods a new identification algorithm is proposed.(5) Based on the algorithms of this paper, we design Fingerprint software.
