TLDR
A novel database, termed as SWAPPED — Digital Attack Video Face Database, prepared using Snap chat's application which swaps/stitches two faces and creates videos, which contains bonafide face videos and face swapped videos of multiple subjects is presented.Abstract:
Advancements in smartphone applications have empowered even non-technical users to perform sophisticated operations such as morphing in faces as few tap operations. While such enablements have positive effects, as a negative side, now anyone can digitally attack face (biometric) recognition systems. For example, face swapping application of Snapchat can easily create “swapped” identities and circumvent face recognition system. This research presents a novel database, termed as SWAPPED — Digital Attack Video Face Database, prepared using Snap chat's application which swaps/stitches two faces and creates videos. The database contains bonafide face videos and face swapped videos of multiple subjects. Baseline face recognition experiments using commercial system shows over 90% rank-1 accuracy when attack videos are used as probe. As a second contribution, this research also presents a novel Weighted Local Magnitude Pattern feature descriptor based presentation attack detection algorithm which outperforms several existing approaches.read more

Deep Face Representations for Differential Morphing Attack Detection
TL;DR: In this article, the authors used subsets of the FERET and FRGCv2 face databases to create a large realistic database for training and testing of morphing attack detection algorithms, containing a large number of ICAO compliant bona fide facial images, corresponding unconstrained probe images, and morphed images created with four different tools.

Face Swapping for Solving Collateral Privacy Issues in Multimedia Analytics
TL;DR: This work proposes de-identification of faces in images by using a generative adversarial network to generate new face images, and uses them to replace faces in the original images and demonstrates that face swapping does not impact the performance of visual descriptor matching and extraction.

Active shape models—their training and application
TL;DR: This work describes a method for building models by learning patterns of variability from a training set of correctly annotated images that can be used for image search in an iterative refinement algorithm analogous to that employed by Active Contour Models (Snakes).
