The Study Of Fingerprint Identification Based On The Attendance Application

Biometric technology is the use of human biological characteristics for their own individual identification technology. Comparing with the facial recognition, retina recognition and other biometric identification technologies, the automated fingerprint identification technology is a better and more practical identification technology.Due to their uniqueness and stability, fingerprints are used as the principal basis of personal identity by people. Automated fingerprint identification system, a technology of fingerprint identification using computer, is convenience, high efficiency, security and reliability. It has been applied in many fields such as financial security, data encryption, electronical business and so on , and will play the more and more vital role in our production and the life.This paper is based on the attendance application, discussed the fingerprint identification process and the algorithm involved in, introduced the problems of the Automated Fingerprint Identification System faced and need to solved. Discussed the pretreatment of gray fingerprint image in details and completed the extracting of deltas and cores. Core points and delta points are considered in the matching algorithm. Improve the problem that the complicated time of matching method which based on the geometric characteristics of point pattern is too higher.There are 5 chapters in the paper. Chapter 1 is Introduction. Chapter 2 is the facing problem based on the fingerprint attendance. Chapter 3 is the process of the verification and the description of the related algorithm. Chapter 4 is the result of experiment. At last is the summary.The main jobs that we do in the paper as followed:(1) Understand the development general situation of The technique that living creature identify, applied foreground, and identify to several kinds of the technique. Study the Software system of the fingerprint attendance and the flow chart.(2) Introduces the various processes and the algorithm involved of the fingerprint identification.
