This work introduces a new feature based on relative minutia position regarding a reference point. The introduction of this feature, allows the elimination of false matches generated by minutiae. Moreover, a novel algorithm for detecting the reference point in fingerprints is introduced. This approach was tested in a manually edited dataset and it proved to be highly tolerant to distorted impressions. Moreover, the new feature was integrated to a recent fingerprint indexing algorithm in an efficient way. Well known fingerprint datasets were employed to show the improvement in accuracy and the superiority of the presented method regarding other proposals.
