Fingerprint Recognition Using Open Algorithms in Frequency and Spatial Domain

Abstract

Undoubtedly the recognition of individuals is essential to ensure the confidentiality of all activity that handle certain exclusivity. Features of a fingerprint are able to make a fingerprint reader device responds differently to each individual. This paper, contains important aspects of fingerprint recognition. We introduced a detailed analysis on the fingerprint conceptualization as biometric pattern, and presents an interesting sequence of algorithms such as the negative laplace filter and the non-stationary analysis of the short time fourier transform, and a flexible algorithm to find the match percentage in the verification process.
