Abstract

Finger knuckle patterns are highly unique and correlated with the anatomy of fingers that involve complex interaction of finger phalanx bones, tissues and interphalangeal joints. Such patterns are increasingly employed for the forensic identification, especially when knuckle patterns are only the piece of available evidence to identify the suspects. Unrelenting hygienic concerns to stop the spread of COVID19 and wide availability of smartphones has attracted renewed attention on developing completely contactless finger knuckle identification capabilities. During this talk, our discussion will focus to uncover enormous potential from various finger knuckle patterns for the completely contactless and online personal identification. We will also discuss on the stability of knuckle patterns, from a database acquired at several years of interval, among the individuals from different age group. Effectiveness of knuckle minutiae and other feature extraction algorithms will also be analyzed. Experimental results from contactless finger knuckle databases, including those from over 700 different subjects, will also be presented. During this talk, I will also present a live demonstration from our completely contactless and online finger knuckle identification system.
