Electronic passport is one of the hottest research fields nowadays due to reported different attacks against various countries. Several attacks such as brute force attack, guessing machine readable zone's information are performed on Basic Access Control Protocol (BAC) due to its low entropy. This paper presents two proposed authentication enhancement techniques for seed key of BAC. The first proposed...
Fingerprint enhancement is a critical step in fingerprint recognition systems. There are many existing contact-based fingerprint image enhancement methods and they have their own strengths and weaknesses. However, image enhancement approaches that can be used for contactless fingerprints are rarely considered and the number of such approaches is limited. Furthermore, the performance of existing contactbased...
Fingerprints are extensively and effectively utilized for proof of identity in recent years. Mostly because of their originality, stability through life, a uniqueness among the people, public acceptance and their least risk of invasion. Fingerprint technology, which is a bio-metric system, is utilized to classify an individual based on their physical qualities. Fingerprint matching is the trendiest...
As one of the key fingerprint identification technology, the fingerprint preprocessing algorithm consists of the segmentation, enhancement, binarization and thinning of fingerprint image. Using Gabor filter designed by ridge orientation of fingerprint implements fingerprint enhancement. It also makes discussion in segmentation, binarization and thinning, and verifies the efficiency of algorithm by...
The deduction of the fingerprint singular points is the most challenging task, it has been used for fingerprint classification and as reference points for minutiae matching and alignment. In this paper, a novel algorithm is proposed for singular points detection, which is based on the orientation reliability. The algorithm starts by enhancing the fingerprint image using the Gabor filter, followed...
Generally, the minutiae sent to the final matching phase are extracted from the skeleton images. The accuracy of minutiae extraction depends on the quality of the skeleton image. This paper presents a novel approach of fully reconstructing the fingerprint images besides using merely the traditional procedures of fingerprint enhancement. The reconstruction would not only improve the quality of the...
Matching unknown latent fingerprints lifted from crime scenes to full (rolled or plain) fingerprints in law enforcement databases is of critical importance for combating crime and fighting terrorism. Compared to good quality full fingerprints acquired using live-scan or inking methods during enrollment, latent fingerprints are often smudgy and blurred, capture only a small finger area, and have large...
Fingerprint image enhancement is an essential preprocessing step in fingerprint recognition applications. In this paper we introduce an approach that extracts simultaneously orientation and frequency of local ridge in the fingerprint image by Gabor wavelet filter bank and use them in Gabor Filtering of image. Furthermore, we describes a robust approach to fingerprint image enhancement, which is based...
This article systematically elaborated the correlation theories of fingerprint recognition technology and several essential algorithms. Combining the characteristic of fingerprint image in the pretreatment process, key technologies of fingerprint pretreatment have been studied, including fingerprint image intensification which is based on the gradation standardization, the directional diagram and...
In this paper, a fingerprint verification method is presented that improves matching accuracy by overcoming the shortcomings of previous methods due to missing some minutiae, non-linear distortions, and rotation and distortion variations. It reduces multi-spectral noise by enhancing a fingerprint image to accurately and reliably determine a reference point and then extract a 129 ?? 129 block, making...
Fingerprint image enhancement is an essential preprocessing step in fingerprint recognition application. There are many authors proposed the different fingerprint enhancement methods. Most present well-known methods are base on Gabor filters. However, the present proposed Gabor filters almost can not be efficient in some cases such as: the local orientation changes rapidly and the fingerprint image...
Accurate reference point detection is crucial for features extraction to improve the performance of fingerprint recognition system. Many reference-point detection algorithms work well in good-quality fingerprints, however, most fail to correctly locate the reference point in poor-quality fingerprints with cracks and scars, dry skin, or poor ridge-and-valley contrast. In this paper, we propose a method...
In fingerprint recognition system, fingerprint feature extraction algorithm requires good quality fingerprint images to produce good results. Therefore, one step in the preprocessing stage is image enhancement to improve the quality of poor fingerprint image, so the minutiae points can be detected with good results. In this paper, we present how this enhancement process in simple minutiae detection...
