[Asia Economy Reporter Hyunju Lee] Sejong University announced on the 31st that a technology for original proof of jpg images developed by Professor Ohjin Kwon's team from the Department of Electronic Information and Communication Engineering has been adopted as an international standard technology. The newly developed technology can prove that altered or tampered jpg images are not originals. It applies both digital signature technology and watermarking technology simultaneously to jpg images and has been adopted as an international standard named JPEG Privacy & Security (ISO/IEC 19566-4). The research team is currently developing a camera that embeds this technology, supported by internal research funds and domestic camera companies, enabling original proof from the moment the image is created. They also plan to provide the software to the JPEG International Standardization Organization for free distribution. The research results have been filed for domestic and international patents, and the core algorithm was published in 'IEEE Access,' an international journal in the electrical/electronic field.
