Outline of Final Research Achievements

With the development of information communications technique, information hiding technique has attracted much attention. It is employed as one of the information security techniques that intend to authenticate information communications technology. Applying the information hiding technique, this study has aimed to realize the concept of high value-added media communications. As a result, this study has proposed some applications of the information hiding technique as well as improved the information hiding technique itself. These results contribute the progress of information communications technique as well as information hiding technique.
