Abstract

                In recent days  ,  many digital finger print image based identification applications are used widely for human identity . Finger print features like minutiae (ridge lines, bifurcation, ridge ending) delta point, core point, texture patterns of ridges and valleys etc., are used for finger print identification. Reliable finger print identification system uses the finger print features to provide higher accuracy . Many finger print identification systems have been proposed based on  minutiae , ridge lines. But these systems   performance are not effective as compared to texture based methods.   In this article , significance of  feature extraction techniques , various texture based finger print identification methods  are investigated and  analysed . Limitations of  minutiae, , and  based identification systems are discussed. Also how effective the texture based identification systems are discussed. A comparative analysis of experimental results of various methods of finger print identification is done. This paper is concluded with the finding of   appropriate method of  texture based feature extraction for  effective identity authentication.
