Reserved Fields of Palette for Data Hiding in Steganography

Palette is organized as- the first three bytes correspond to RGB components and the last byte is reserved / unused but could obviously represent the alpha channel. In this paper, we present a new steganographic technique using the last byte for data hiding in organized pattern through algorithm. The concept of Magic Number has been utilizing hiding of data. Numerical experiments indicate that the new technique introduces no distortion to the carrier image. A technique that introduces no distortion to the carrier image will generally cause changes that are more difficult to detect, and will therefore provide more security.
