Title of the Talk: Face Morphing Attack Detection
Presenter: Christoph Busch
Abstract: Widespread deployment of Automatic Border Control (ABC), along with electronic Machine Readable Travel Documents (eMRTD) for traveler verification, has enabled a prominent use case of face biometrics in border control applications. The trust anchor are biometric passports. Many countries issue eMRTD passports on the basis of a printed biometric face photo submitted by the applicant, a procedure which allows the possibility of the photo being either altered to beautify the subject’s appearance or morphed to conceal his/her identity. If an eMRTD passport is issued with a morphed facial image, two or more data subjects can then use it to pass a border control. This talk will discuss the morphing attack problem and indicate early solutions to detect such morphed facial images.

Title of the Talk: Perceiving Faces in 2D Images from 3D Perspective
Presenter: Qijun Zhao
Abstract:The face reveals a lot of information of humans, for example, identity, race, gender, age, emotion, intention, and health. 3D face models are thus widely studied in many disciplines. Yet, acquisition of 3D faces is still much more expensive and less convenient than acquisition of 2D face images, making it unaffordable to deploy 3D face technology in many real-world applications. Our research aims to reconstruct 3D face shapes from either single or multiple uncalibrated 2D face images to facilitate the perception of faces. This talk will introduce our recent progress along this direction. The methods we propose enable not only efficient generation of 3D face models when only 2D imaging devices are available, but also effective exploration of 3D face information for improving facial identity and expression recognition accuracy. We believe that 3D faces will play increasingly important roles in many applications with the rapid development of 3D face acquisition, modeling and processing methods.

Title of the Talk: Federated Learning-based Biometrics Authentication on Mobile Devices
Presenter: Vishal Patel
Abstract: Federated learning is a decentralized machine learning approach that enables multiple local devices to collaboratively learn a global model with the help of a server while preserving privacy of data at local devices. In this talk, I will first give an overview of federated learning and then present its application in biometrics-based active authentication. I will discuss merits and drawbacks of available approaches and identify promising avenues of research in this rapidly evolving field.
