Accurate Personal Identification using Finger Knuckle and Finger Vein Biometric Images

Slides (pdf)


There has been tremendous growth in the demand for hand-based biometrics systems that can offer more user friendly and accurate biometrics identification. The anatomy of fingers is quite complicated and responsible for a variety of unique features that can be conveniently recovered under the visible and near infrared imaging. This talk will focus on the two relatively new biometric modalities, i.e. finger-knuckle and finger-vein, which have shown to offer more accurate and secured personal identification. These two modalities can be simultaneously (single imaging shot) acquired with the fingerprints, extremely difficult to spoof as such attempt will require complicated surgical alterations, and therefore offers a low-cost and more reliable countermeasure for secured biometrics access. We will discuss on the development of state of art algorithms for the automated segmentation and the matching of finger vein and finger knuckle images. Some insights on the stability of these modalities, challenges in the development of first publicly available finger-vein database, deep learning based robust finger-vein identification or the investigations into the world's largest finger knuckle database that introduced first minor and second minor finger knuckle modalities for the biometrics community, will also be discussed during this talk.


Ajay Kumar received the Ph.D. degree from The University of Hong Kong, Hong Kong, in 2001. He was an Assistant Professor with the Department of Electrical Engineering, IIT Delhi, Delhi, India, from 2005 to 2007. He is currently an Associate Professor with the Department of Computing, The Hong Kong Polytechnic University. His current research interests are on biometrics with an emphasis on hand biometrics, vascular biometrics, iris, and multimodal biometrics.

He holds six U.S. patents, and has authored on biometrics and computer vision based industrial inspection. He was on the Editorial Board of the IEEE Transactions on Information Forensics and Security from 2010 to 2013, and served on the program committees of several international conferences and workshops in the field of his research interest. He was the Program Chair for ICEB 2010 (Hong Kong) and Program Co-Chair for the IJCB 2011 (Washington DC), ICB 2013 (Madrid), and CVPR 2013-2017 Biometrics Workshops. He has also served as the General Co-Chair of the IJCB 2014 (Tampa) and the ISBA 2015 (Hong Kong) and delivered the first tutorial on contactless 3D fingerprint identification during the CVPR 2015 held in Boston, USA. He serves on the Editorial Board of Pattern Recognition Journal and has served on the IEEE Biometrics Council as the Vice President (publications) during 2011-2015. He is a Fellow of IAPR and Senior Member of IEEE.
