About

Kuntal Dey is a researcher whose work sits at the intersection of human-computer interaction, cybersecurity, and affective computing. He is best known for pioneering novel authentication mechanisms, most notably through his landmark paper "EyamKayo" (2017, 6 citations), which introduced the first interactive CAPTCHA system that leverages real-time eye gaze and facial expression analysis. This innovative approach moves beyond traditional text or image-based challenges, creating a more natural and secure way to distinguish humans from automated bots. By integrating behavioral biometrics into security protocols, Dey's work addresses critical vulnerabilities in online systems while enhancing user experience. Though a relatively recent contribution, "EyamKayo" has already garnered attention for its creative fusion of computer vision and usability, laying the groundwork for more adaptive, human-centric security solutions. Dey's research continues to explore how subtle, involuntary human responses can be harnessed to build smarter, more resilient digital defenses—a direction with profound implications for privacy, accessibility, and trust in an increasingly automated world.
