A New Multi-filter Framework with Statistical Dense SIFT Descriptor for Spoofing Detection in Fingerprint Authentication Systems
(2021-01-01)
Fingerprint-based authentication systems represent what is most common in biometric authentication systems. Today’s simplest tasks, such as unlocking functions on a personal cell phone, may require its owner’s fingerprint. ...
Feature Fusion for Fingerprint Liveness Detection: A Comparative Study
(Institute of Electrical and Electronics Engineers Inc., 2017-10)
Spoofing attacks carried out using artificial replicas are a severe threat for fingerprint-based biometric systems and, thus, require the development of effective countermeasures. One possible protection method is to ...
Detection of Giardia lamblia antigen in children living in a Peruvian periurban shantytown (Pueblo Joven)
(American Society for Microbiology, 1991)
Stool microscopy and an enzyme-linked immunosorbent assay (ELISA) for Giardia lamblia antigen detection were compared for detecting G. lamblia in 30 Peruvian infants. Of 1,131 fecal specimens, G. lamblia was detected by ...

ON THE IMPORTANCE OF USING HIGH RESOLUTION IMAGES, THIRD LEVEL FEATURES AND SEQUENCE OF IMAGES FOR FINGERPRINT SPOOF DETECTION
(Ieee, 2015-01-01)
The successful and widespread deployment of biometric systems brings on a new challenge: the spoofing, which involves presenting an artificial or fake biometric trait to the biometric systems so that unauthorized users can ...
