Open Challenges in Detecting Sophisticated and Photorealistic Deep Fake Images

[CFAR Distinguished Professor Lecture Series]
Open Challenges in Detecting Sophisticated and Photorealistic Deep Fake Images (Hybrid Event) by Professor Ajay Kumar
9 Sep 2022 | 10.00am (Singapore Time)

There has been a growing emergence of disinformation campaigns using photorealistic fake images in mainstream media outlets and photo hoaxes that land in our e-mails. Accurate detection of such sophisticated and real-look-like fake images presents a challenge in preserving social harmony, security, and privacy-related concerns in our society. A range of advanced methods has been introduced in the literature to detect sophisticated fake images that are often generated by powerful generative adversarial network (GAN) based methods. 

In this talk, Prof Ajay Kumar from The Hong Kong Polytechnic University will highlight the increasing reliance on such popular and sophisticated fake image detection methods available in the scientific community. He will also discuss such fake image detectors and present a scientific pipeline that can compromise the detection performance when the proposed methods are incorporated. The analysis presented during this talk will caution the forensic community on the reliability of widely employed GAN-generated fake image detectors, and the need for significant advances to address such open challenges.

Prof Ajay Kumar received his Ph.D. degree from The University of Hong Kong, Hong Kong, in 2001. He was an Assistant Professor with the Department of Electrical Engineering, Indian Institute of Technology (IIT) Delhi, India from 2005 to 2007. He is currently working as a Professor with the Department of Computing, The Hong Kong Polytechnic University. Prof Kumar’s current research interests are in biometrics, with an emphasis on hand biometrics, vascular biometrics, iris, and multimodal biometrics. He holds seven U.S. patents, and has authored a book on ‘Contactless 3D Fingerprint Identification’. He is currently serving on the Editorial Board of IEEE Transactions on Pattern Analysis and Machine Intelligence and was on the Editorial Board of the IEEE Transactions on Information Forensics and Security from 2010-2013. He has served on the program committees of several international conferences and recently acted as an area chair for ECCV 2022, CVPR 2022-2019, and program chair for CVPR 2013-2022 Biometrics Workshops. He was also the General Co-Chair of the IJCB 2014 (Tampa), ISBA 2015 (Hong Kong), and General Chair for WIFS 2018 held in Hong Kong. Prior to his appointment as President of the IEEE Biometrics Council, Prof Kumar held the position of Vice President for publications from 2011-2015. He is a Fellow of IAPR and IEEE since 2016 and 2018 respectively.
