Abstract

In recent years, it is important to increase people’s attention on digital signage because of the increase of LED digital signage. In order to provide joyful experiences when viewing digital signage, we have proposed waving-hand steganography using a high-frame-rate LED panel, where an embedded secret image is decodable by viewing through a waving hand [1]. We realized technique of switching two images at a high frame rate and embedding information in color sequential display [2]. These were steganography for a still image.
