Fingerprint features have been widely used for verifying the identity of an individual. Automatic fingerprint verification systems use ridge flow patterns and general morphological information for broad classification, and minutiae information for verification. The ridge flow patterns and morphological information are referred to as level-1 features, while ridge endings and bifurcations, also known as minutiae, are referred to as level-2 features. With the availability of high resolution fingerprint sensors, it is now feasible to capture more intricate features such as ridge path deviation, ridge edge features, ridge width and shape, local ridge quality, distance between pores, size and shape of pores, position of pores on the ridge, permanent scars, incipient ridges, and permanent flexure creases. These fine details are characterized as level-3 features and play an important role in matching and improving the verification accuracy.

The main objective of my PhD research is to develop a fast and accurate automated fingerprint verification algorithm that incorporates both level-2 and level-3 features. First, a fast Mumford-Shah curve evolution algorithm is used to extract four level-3 features namely, pores, ridge contours, dots, and incipient ridges. For improving the fingerprint verification performance, we further propose an evidence-theoretic multimodal unification approach using belief functions that takes into account the variability in level-2 and level-3 characteristics. Experimental results and statistical tests on a database of 700 classes show the effectiveness of the proposed algorithms. Compared to existing algorithms, the proposed approach is computationally efficient, and the verification accuracy is not compromised even with partial fingerprints.
