Bio-metric Fingerprint Authentication using Ridge Feature

Bio-metric is automated method of identifying a person or verifying the identity of a person stand on a physiological or behavioral characteristic.Many body parts, personal characteristics have been suggested and used for bio-metric security scheme. Which include fingerprint,hands,face,eyes,voice etc. So all physiological characteristics are the permanent identification of every person by birth and it never change throughout the life.There are number of Bio-metric techniques available to fulfill the different kinds demand in the market.Every method consists number of advantages compared to the others. But as if now there is no such method able to completely satisfy the current security scheme.So because of this research is continuously going on to find out the newer methods that will provide a higher security.Here, the different methods of bio-metric authentication are presented.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 finer points.These finer points along with their position and orientations are saved as feature.
