Enhancing Steganography in Digital Images

The history of steganography can be traced back to ancient civilization - the Persian and Greek conflict around 480 B.C and ancient Egyptian civilization - when steganography was first reported to exist. Steganography is the process of hiding information in a multimedia carrier. Steganalysis, which is the official counter attack science, has defeated Steganographic algorithms whether they are based on the traditional spatial domain or the transform domain. This paper discusses the possibility of embedding data in the frames of video files. We call it adaptive as we select the specific region of interest (ROI) in the cover image where we can safely embed our data. We chose these regions based on human skin tone colour detection. As such the method is obviously constrained to image or video files with face instances present.
