SEOUL, April 17 (AJP) - Professor Kim Min-gyu at Kookmin University (KMU) has developed a unified framework to ensure the safety of artificial intelligence models that generate images and videos. The research, which addresses issues like copyright protection and harmful content, has been selected for an oral presentation at the International Conference on Learning Representations (ICLR) 2026. Kookmin University (KMU) said Friday.
Professor Kim Min-gyu worked as the lead author on the study alongside Professor Kim Young-heon and Professor Park Mi-jeong from the University of British Columbia (UBC). The project received support from the Institute for Information and Communications Technology Planning and Evaluation (IITP) and the Canadian Institute for Advanced Research (CIFAR).
The research introduces a system called Safety-Guided Flow (SGF) to improve how AI models handle sensitive data and requests. This framework unifies existing safety techniques, proving that previous methods were specific cases of a broader mathematical concept known as maximum mean discrepancy potential.
The team also identified what they call a critical time window in the AI generation process. Using control barrier function theory, they demonstrated that safety controls must be applied most strictly during the initial stages of image creation before being gradually phased out.
Tests of the SGF system showed improved performance in defending against harmful content and preventing the AI from accidentally memorizing its training data. These improvements are seen as a foundation for making generative AI safer for commercial and public use in South Korea and abroad.
"This research provides a new analytical framework that allows us to understand scattered safety research from a single, unified perspective," Professor Kim Min-gyu said. "In the future, it can be used as a core technology to ensure safety as diffusion and flow matching models are put into practical use in high-risk areas such as autonomous driving, medicine, and content creation."
