About

Dr. Seema Nagar is a pioneering researcher in human-computer interaction and cybersecurity, best known for her groundbreaking work on next-generation authentication systems. Her most cited paper, "EyamKayo" (2017, 6 citations), introduces the first-of-its-kind interactive CAPTCHA that leverages eye gaze and facial expression-based human interactions to distinguish humans from software robots. This innovative approach addresses critical limitations of traditional text-based CAPTCHAs, offering a more secure and user-friendly alternative by harnessing natural human behaviors. Dr. Nagar's research sits at the intersection of biometrics, artificial intelligence, and usability, with her work on EyamKayo laying the foundation for more accessible and robust security protocols. Though her citation count is modest, the conceptual impact of her work is significant, as it opens new avenues for inclusive authentication methods that do not rely on visual or linguistic proficiency. Her contributions are particularly relevant in an era where bot detection remains a pressing challenge, and her novel use of multimodal human signals continues to inspire further research in adaptive and intuitive security systems.
