According to the properties of fingerprint minutiae in fingerprints

this paper proposed a fingerprint verification algorithm based on fingerprint classification.The core and delta information is used to classify the fingerprint

and then the bifurcation ridge comparability is used to find reference minutiae according to the comparability of two ridges on which the highly reliable bifurcation lied.Meanwhile

in order to solve the problem that the reference minutiae filtering would be influenced by noise

taking the advantage of the relationship between the reference minutiae and the neighboring minutiae to filter the final reference minutiae and determine the transform parameters.And finally the algorithm implemented the fingerprint matching using the variable bounding box.The experiment results indicated that this algorithm had high speed and accurateness in locating the reference minutiae

more efficiency in performing fingerprint matching

as well as fastness and precision.
