Identifying distorted ngerprint images is a major problem in ngerprint recog-nition systems. Several techniques, such as the minutiae triplets technique, have been proposed for minutiae matching and indexing. The minutiae triplets technique however is largely aected by minutiae distortions and occlusions and hence can rarely produce a stable feature set. In this paper, the characteristics of theminutiae quadruplets and the minutiae triplets structures are compared. The minutiae quadruplet technique is proposed as a better technique because the features are robust to minutiae distortions and occlusions and it eliminates the known drawbacks of the minutiae triplet technique.
