Speaker: Dr. Rajesh Kumar

Abstract: Physical biometrics, such as fingerprints, faces, and irises, have been widely studied for user authentication, identification, health monitoring, and personalization. Despite their success, these technologies have important limitations, particularly for applications that require continuous and unobtrusive user verification without demanding explicit attention or interaction from the user.
Behavioral biometrics offer a complementary approach by recognizing individuals through patterns in everyday activities, such as reading (gaze patterns), typing (keystroke dynamics), swiping (touch dynamics), walking (gait), and speaking (voice). Beyond user verification, these behavioral signals can provide valuable insights for applications such as authorship attribution, identity linkage in social media, and health monitoring.
This talk will introduce the fundamentals of behavioral biometrics and illustrate their potential through several research problems we have investigated. I will discuss what can be learned from the subtle patterns in how people interact with devices, the opportunities these signals create, and challenges that remain. The talk will conclude with emerging research directions and opportunities for using behavioral biometrics in increasingly intelligent and personalized computing systems.

Bio: Dr. Rajesh Kumar is an Associate Professor of Computer Science at Bucknell University, USA. He received his Ph.D. in Computer Science from Syracuse University and holds master’s degrees from Louisiana Tech University and Jawaharlal Nehru University, New Delhi. His research investigates computational models of human behavioral signals across three interconnected areas: behavioral biometrics for identity and cybersecurity, integrity and authorship verification in the age of generative AI, and human-centered and accessible AI. He has published over 30 papers in leading IEEE and ACM venues, including ACM CCS, ACM TOPS, IEEE T-BIOM, and IEEE IJCB. His research has received numerous distinctions, including Best Paper, Highest Impact Paper, Best-Reviewed Paper, Honorable Mention Paper, and Best Poster awards, and he has received four Outstanding Reviewer Awards from IEEE IJCB. He has also served on multiple National Science Foundation (NSF) review panels evaluating more than $20 million in research proposals. He has mentored more than 40 undergraduate researchers, whose work has received national and international recognition.
