| Research Abstract |
With the rapid growth in communication channels and terminals, scalable transmission has become popular. First, we have developed a secure and flexible access control scheme for scalable media. Next, we have also proposed a color-based access control scheme by sorting indexed colors in palette-based images. Furthermore, our proposed sorting scheme for indexed colors has applied to information hiding for palette-based images.
