Minutiae-Based Fingerprint Matching

At today, thanks to the high discriminability of minutiae and the availability of standard formats, minutia-based fingerprint matching algorithms are the most widely adopted methods in fingerprint recognition systems. Many minutiae matching algorithms employ a local minutiae matching stage followed by a consolidation stage. In the local matching stage, local minutiae descriptors are used, since they are discriminant and robust against typical perturbations (e.g., skin and non-linear distortion, partial overlap, rotation, displacement, noise). Minutiae Cylinder-Code representation (MCC), recently proposed by the authors, obtained remarkable performance with respect to state-of-the-art local minutiae descriptors. In this chapter, the basic principles of minutiae-based techniques and local minutiae descriptors are discussed, then the MCC approach is described in detail. Experimental results on standard benchmarks such as FVC2006 and FVC-onGoing are reported to show the great accuracy and efficiency of MCC.
