Recent Trends in Image Information Recovery Using Leaked Electromagnetic Wave from Electronic Equipment

Abstract

Information input/output technology has been employed in various fields in our modern lives, and it is almost impossible for society to function without the devices based on this technology. Therefore, security issues associated with such electronic devices have attracted extensive attention. This study thoroughly reviews various TEMPEST-related research outcomes and trends. It contains both conventional and deep learning-based image processing techniques and research involving realistic scenarios, including concrete walls, information recovery under multiple devices, and reconstruction of color information.
