Automated spoof-detection for fingerprints using optical coherence tomography

Author: Darlow, LN ; Webb, L ; Botha, N Date: May 2016 Fingerprint recognition systems are prevalent in high-security applications. As a result, the act of spoofing these systems with artificial fingerprints is of increasing concern. This research presents an automatic means for spoof-detection ... Read more
Extracting subsurface fingerprints using optical coherence tomography

Author: Akhoury, SS ; Darlow, LN Date: Feb 2015 Physiologists have found that fingerprint patterns exist in the inner layers (viz. papillary junction) of the skin of the fingertip. However, conventional acquisition systems do not have capabilities to extract fingerprints at subsurface ... Read more
Fingerprint matching with optical coherence tomography

Author: Moolla, Yaseen ; Singh, A ; Saith, E ; Akhoury, S Date: Dec 2015 Fingerprint recognition is an important security technique with a steadily growing usage for the identification and verification of individuals. However, current fingerprint acquisition systems have certain disadvantages, which include the ... Read more
High resolution feature extraction from optical coherence tomography acquired internal fingerprint

Author: Khutlang, Rethabile ; Khanyile, Nontokozo P ; Makinana, Sisanda ; Nelwamondo, Fulufhelo V Date: May 2016 Biometric fingerprint scanners scan the external skin features onto a 2D image. The performance of the automatic fingerprint identification system suffers if the finger skin is wet, worn out, fake fingerprint is used et cetera. Swept source ... Read more
Internal fingerprint zone detection in optical coherence tomography fingertip scans

Author: Darlow, LN ; Connan, J ; Akhoury, SS Date: Apr 2015 Optical coherence tomography (OCT) is a high-resolution imaging technology capable of capturing a three-dimensional (3-D) representation of fingertip skin. The papillary junction—a junction layer of skin containing the same topographical ... Read more
Latent fingerprint wavelet transform image enhancement technique for optical coherence tomography

Author: Makinana, S ; Khanyile, PN ; Khutlang, Rethabile Date: Sep 2016 In crime investigation, fingerprint identification plays a major role in identifying culprits. However, traditional procedure of acquiring latent fingerprint tends to be destructive and leads to a limitation of not being able to do further ... Read more
Novelty detection-based internal fingerprint segmentation in optical coherence tomography images

Author: Khutlang, Rethabile ; Machaka, Pheeha ; Singh, Ann ; Nelwamondo, Fulufhelo V Date: Aug 2017 Biometric fingerprint scanners scan the external skin's features onto a 2-D image. The performance of the automatic fingerprint identification system suffers first and foremost if the finger skin is wet, worn out or a fake fingerprint is used. ... Read more
Novelty detection-based internal fingerprint segmentation in optical coherence tomography images

Author: Khutlang, Rethabile ; Nelwamondo, Fulufhelo V Date: Dec 2014 Biometric fingerprint scanners scan the external skin features onto a 2-D image. The performance of the automatic fingerprint identification system suffers if the finger skin is wet, worn out, fake fingerprint is used et cetera. In this paper, ... Read more
Optical coherence tomography as a diagnostic tool

Author: Singh, A ; Karsten, AE Date: Jul 2011 Optical Coherence Tomography (OCT) has been used in biomedical applications as a method to non-invasively detect changes occurring in tissue such as the detection of skin cancer. The effect of skin tone on detection of skin cancer has however ... Read more
Optical coherence tomography, In vivo human hand explorer, optical coherence microscope

Author: Jonathan, E ; Dam, JS Date: Jul 2008 The hand palm is an important human body part primarily for physical manipulation of the environment. For example, palmar hyperhidriotics report a low quality of life due to excessive palmar sweating disrupting normal palm use. As a body part ... Read more
Segmentation of forensic latent fingerprint images lifted contact-less from planar surfaces with optical cohererence tomography

Author: Khutlang, Rethabile ; Nelwamondo, Fulufhelo V ; Singh, A Date: Jul 2015 Lifting latent fingerprints through means that do not make contact with the surface where the fingerprint is imprinted, is advantageous in many ways. Some of these advantages include: being able to lift the print multiple times; there is no ... Read more
Study on internal to surface fingerprint correlation using optical coherence tomography and internal fingerprint extraction

Author: Darlow, LN ; Connan, J Date: Nov 2015 Surface fingerprint scanners are limited to a two-dimensional representation of the fingerprint topography, and thus, are vulnerable to fingerprint damage, distortion, and counterfeiting. Optical coherence tomography (OCT) scanners are able ... Read more
