Research interests cover the following topics
Topics	Description
Deep Learning Artificial Intelligence	Various Deep Learning technologies are investigated to derive the digital watermarking and forensic solutions.
Digital Watermarking	We have developed a robust watermarking and fingerprinting algorithm for image and video. The Video Watermarking Software which use ‘Digital Watermarking Engine’ we developed was selected as one of 40 national key technologies in 2007.
Computational Forensics	We are now investigating multimedia forensics. Particularly image and video forensics are our main concern. Various fundamental technologies have been investigated and developed for the image and video forensics.
Steganography / Steganalysis	We have investigated secret communication and the monitoring technologies on the internet.
Deepfake	Deepfake detection based on artificial intelligent technology, such as GAN, CNN is intensively investigated due to the various research requirements.
