About

Yara Saud Aljarbou is a cybersecurity researcher focused on human-computer interaction and web security, with a particular emphasis on CAPTCHA systems. Her most cited work, "Improving of Current CAPTCHA Systems" (2019), addresses the growing threat of automated bot attacks on essential web services like search engines and email. In this paper, she systematically analyzes vulnerabilities in existing CAPTCHA designs and proposes enhancements to balance usability with security—a critical challenge as bots become increasingly sophisticated. With 5 citations, this foundational contribution has informed subsequent research on accessible yet robust authentication mechanisms. Aljarbou’s work sits at the intersection of user experience and cybersecurity, aiming to protect digital infrastructure without frustrating legitimate users. Her research is particularly relevant as the internet expands and automated threats evolve, making her contributions valuable for both academics and practitioners developing next-generation web defenses. She continues to explore ways to strengthen online authentication, ensuring that security measures remain effective against emerging attack vectors while maintaining accessibility for all users.
