Biometric fingerprint authentication with minutiae using ridge feature extraction

摘要

Fingerprint matching is done using many ways, for example considering ridge features. As an extension we propose to use bifurcations along with ridge patterns. The ridges along with bifurcations are considered as minutiae. These minutiae along with their position (i.e. x and y co-ordinates) and orientations are saved as features. We propose a novel matching scheme to detect the matched minutiae pairs incrementally. Following that, the maximum score is computed and used as the final matching score of two fingerprints.
