About
Okkyung Choi’s research sits at the intersection of cybersecurity, robotics, and mobile services, with a focus on securing emerging technologies against evolving threats. Her work addresses critical vulnerabilities in social tagging systems, robot vision, and NFC-based applications, proposing novel techniques to prevent rank manipulation, geometric image attacks, and authentication breaches. Notably, she developed an extended DCT domain watermarking method to protect robot vision from geometric attacks and designed a secure NFC payment authentication protocol for service robots, ensuring safe transactions in automated environments. Her studies on distributed big data processing and user authentication for human-friendly robot services further highlight her commitment to robust, scalable security frameworks. Though her citation counts are modest—each of her top papers garnering 2–3 citations—her contributions are foundational to the security of robotic and mobile platforms, particularly in contexts like mobile printing and payment agency. Choi’s work is especially relevant for researchers exploring the convergence of IoT, robotics, and cybersecurity, offering practical defenses for real-world applications in an increasingly connected world.
