Face spoofing detection using surface and sub-surface reflections analysis

Face Spoofing Detection Using Image Distortion Features

Accurate biometric system for authentication is the need of the hour in today’s scenario. In face spoofing attack a person tries to pretend to be a valid user by using photo or video of an authorized person and gets illegitimate access. Hence it is essential to develop a robust and authentic face spoof detection system in order to protect the privacy about the person. Centre of attraction of th...

Face-Spoofing 2D-Detection Based on Moiré-Pattern Analysis

Biometric systems based on face recognition have been shown unreliable under the presence of face-spoofing images. Hence, automatic solutions for spoofing detection became necessary. In this paper, face-spoofing detection is proposed by searching for Moiré patterns due to the overlap of the digital grids. The conditions under which these patterns arise are first described, and their detection i...

Nanoscale Surface and Sub-Surface Chemical Analysis of SiGe Nanowires

Si/Si1-xGex axial heterostructured nanowires (hNW) are under investigation for downscaling of metaloxide-semiconductor field-effect transistors (MOSFETs). New architectures based on vertically aligned nanowires tunnel-FETs are promising candidates for reduced power dissipation and low voltage operation [1]. The axial growth of lattice mismatched heterostructures would allow band-gap engineering...

Face Spoofing Detection In Biometric System

Face recognition frameworks are a part of facial image processing applications. [1] It has been a active research topic in the last two decades and its methods are presently sent in access control frameworks. It is the most common method for biometric distinguishing proof and has the advantage of non intrusiveness over the other biometric strategies, for example, irises and fingerprints. So the...
