Dong-Eui University Master's Student Gong Byungjun Wins Excellent Paper Award at Korea Internet Electronic Commerce Society

Presentation of "AI-Based Smishing Risk Alert System to Protect Digitally Vulnerable Groups"

Gong Byungjun, a master's student in the Department of Artificial Intelligence at the Dong-Eui University Graduate School, received the Excellent Paper Award at the 2025 Korea Internet Electronic Commerce Society Fall Conference, which was held at the Dong-Eui University International Building from November 6 to 7. He was recognized for his paper titled "Development of an AI-Based Smishing Risk Alert System to Protect Digitally Vulnerable Groups."

Together with Professor Jeong Seokchan, Director of the AI Grand ICT Research Center, Gong developed a system that analyzes text message content and determines in real time whether a message is a smishing attempt, utilizing the artificial intelligence language model 'RoBERTa.'

This system is equipped with a feature that immediately sends alerts to both users and their guardians upon detecting a suspicious message. It was trained on over 6,000 real-world text messages, achieving a high accuracy rate of 94.85%, an F1 score of 0.800, and an AUC of 0.980.

In particular, to reduce the false positive rate for smishing detection, the team optimized the classification threshold and added an automatic organization function to prevent duplicate detection of messages, thereby establishing an efficient and highly reliable security response system.

Professor Jeong Seokchan stated, "This research is a meaningful achievement that demonstrates how artificial intelligence can help protect socially vulnerable groups and strengthen the digital safety net." He added, "We will continue to pursue research that creates social value, centered around the AI Grand ICT Research Center."
